3. SHIPPING, HANDLING AND STORAGE
On receipt of motor after delivery, ensure that no damage has occurred during transit. If there is
any evidence of damage to the packaging then the motor must be inspected and checked by
qualified personnel before putting into service.
This equipment must be lifted at the appropriate lifting points attached to the frame. The lifting
gear must be suitable and have the carrying capacity of the full weight as indicated in the data
sheet and on the motor name plate.
Precautionary measures should be taken to protect the motor from vibration, water and extreme
temperature variations during transit. Damage can occur to the bearings from vibration and to the
windings from water and extreme temperature changes through condensation.
Transit clamps should be used to prevent the shaft from moving during transit. It is important to
remove these clamps (if fitted) before attempting to install the motor. These clamps should be
removed during storage to allow the shaft to be rotated by hand on a regular basis, at least once
every four weeks.
To prevent damage to the bearings it is recommended that the shaft is given a few turns by hand
every four weeks to load the bearing at different places randomly.
If motors are to be stored before installation, precautions must be taken to prevent deterioration.
Motors should be stored in a dry condition, standing clear from damp, free from condensation
and protected from extremes of temperature. If damp storage cannot be avoided then connect the
motor heaters. Adequate precautions must be taken for electrical safety as parts of the motor will
be live.
The motors should be protected from the ingress of dust, especially concrete/cement dust. When
protecting motors from dust, care should be taken that condensation is not caused.
Motors must be stored away from corrosive or chemically damaging fumes.
Damage can be caused to ball and roller bearings if these are subject to vibration.
It is recommended that the motors are thoroughly inspected at 6 monthly intervals. See Section 8
– General Inspection and Maintenance.
Inspect bearing grease before putting motor into operation and renew if it has been deteriorated.
Contact LTI for the replacement interval of grease under long storage periods.
Check insulation resistance before putting motor into operation. If this is less than 1 Megohm,
carry out drying operation.
REV 00 Page 7 of 18
4. INSTALLATION AND COMMISSIONING
Before putting this machine into service, it is important that checks be made to ensure that
the machine is suitable for use in the operating area classification. – See attached
certifications if applicable.
Refer to EN 60079-14 for installation instructions and any National and/or Site Safety Standards
(Within Europe), along with all applicable National, Industry and Company Standards and
Practices for Machinery Installations for all other regions.
If the motor is to be installed in a potentially explosive atmosphere, perform an ignition hazard
assessment in accordance with EN 13463-5 (Non electrical equipment intended for use in
potentially explosive atmospheres – Protect by constructional safety) to ensure the original
approval has not been compromised.
On receipt of motor after delivery, ensure that no damage has occurred during transit. If there is
any evidence of damage to the packaging then the motor must be inspected and checked by
qualified personnel before putting into service.
The motor must be lifted using the facilities provided.
Ensure that the motor rating plate data meets the required specification exactly. Operating the
motor outside the stated design limits could cause a potential hazard and will invalidate the
certification and manufacturers warranty.
The installation must provide for adequate guarding of rotating or heated parts. Where fitted,
these guards must be in position and secured.
Adjustments or measurements must not be made through ventilation or similar openings unless
the motor has been disconnected from the supply.
Any cover provided for live electrical parts or connections must be in place, to ensure that
ingress protection IP54 minimum is maintained.
Power cables to the motor must be of adequate current carrying capacity and rated for the
appropriate voltage. These cables must meet the requirements of the industry standards, local and
national electrical codes.
If operating in a hazardous area, the motor must always be installed using suitable cable
glands or adapters that have been certified by a Notified Body as meeting the requirements
of ATEX Directive 94/9/EC.
When the motor is supplied with loose (“Flying Leads”) cables permanently connected to it,
these cables must be protected and the free ends of the cable must be connected using an
approved method. Ensure that precautions are taken to prevent disconnection whilst energized.
Incoming cables must be suitably clamped, secured and insulated.
REV 00 Page 8 of 18
If used the RTD‟s/Kilxons used for overload protection must be connected to separate (i.e. Not
part of the VFD) circuit. The RTD/Klixon circuit must be set to no more than 170ºC. This will
provide overload and over temperature protection as specified on the certificate. See section 6.
The motor must be grounded (earthed) in accordance with EN 60079-14 and any National and/or
Site Safety Regulations or Industry Standards if none of the others are applicable.
Precautions must be taken to avoid vibration, high/low temperature extremes, corrosive and dirty
environments. If in doubt, contact LTI.
All circuits must be connected in accordance with the connection diagram supplied with the
motor along with this manual and all applicable drawings.
It is essential that the motor is supplied with sufficient ventilation from ambient air. It is
recommended that the controls for the ventilation system operate in conjunction with the main
motor drive system and ensures that ventilation is available at the same time as the motor starts.
If the motor is operated without cooling air, then heating will occur and the drive will trip on
over temperature. To prevent this, it is recommended that a zone approved air pressure switch,
which forms part of an intrinsically safe circuit, is fitted within the ventilation system, or the
cooling blower motor is interlocked to prevent the motor stating without the blower running.
Confirm that air flow is sufficient, that ventilation openings are free from obstruction and re-
circulation of the motor outlet air is not possible.
Before starting it is necessary to confirm that the shaft is free to rotate.
The motor must be run without excessive vibration. Ensure that the application adheres to this
equipment.
Drain points must be open and free from obstruction.
Ensure that a suitable coupling is used for the application of the motor.
Check alignment of the motor coupling to ensure there is no more than five thousandths of an
inch in misalignment.
Soft Foot, a condition where the four mounting feet are not in the same plane causing the frame
to distort, should be avoided to obtain proper alignment. A measurement of ±1.0 mils during
installation and ±1.5 is acceptable.

REV 00 Page 9 of 18
Ensure that any and all items used to secure the motor shaft during shipping have been removed
and that the motor shaft rotates freely prior to start-up.
Check the motor heaters. See Section 7.
5. OPERATION
The motor is rated S1 for continuous duty and is designed to work without constant supervision,
however, a periodic check of its performance is advocated.
The normal reading of ammeters under all conditions of the operation of the machine should be
known and if it deviates from the normal, the machine should be stopped (when operating
conditions permit) and the system inspected for faults.
When the machine is under normal operating conditions the frame will increase in temperature
over the ambient. There are thermal devices fitted to ensure that this rise in temperature does not
become a hazard.
6. THERMAL PROTECTION (REQUIRED FOR ATEX APPLICATION ONLY)
The motor will be fitted with over temperature protection for the stator windings. If specified at
the time or order, bearing temperature monitoring facilities can also be fitted. Refer to the motor
data sheet for number and type of thermal protection used.
It is the responsibility of the end user to connect the thermal protection that is fitted to the motor
to ensure safe operation.
Thermal protection for the windings must form part of an intrinsically safe circuit. The standards
require that one thermal protection device is fitted in each phase as a minimum. It is essential and
fundamental to the ATEX certification, that the thermal protection thermal protection is
connected to a separate trip circuit, which will remove power to the Variable Frequency Drive to
protect the motor from overheating and thus prevent a potential explosion hazard occurring.
One thermal protection device per phase must be connected to a separate and intrinsically safe
control circuit. This ensures that thermal protection is always maintained, even in the event of a
fault with the drive. It is required that the thermal sensing devices cause the drive circuit
breaker to open on rise of temperature. This circuit breaker must require a manual reset.
Failure to adhere to this requirement may cause the certification to become void.
The additional set of three RTD‟s may be routed back to the inverter drive for control and/or
temperature monitoring.
Thermal devices will be stated in the motor data sheet. Typically, these will be RTDs (PT100),
or Klixons.
REV 00 Page 10 of 18
7. HEATERS
Heaters are fitted integral to the motor winding during manufacture. To prevent condensation
causing deterioration to the insulation resistance of the winding, heaters should be switched on
when the motor is not in operation. Adequate safety measures must be taken to ensure that access
to live connections cannot be made whilst the heaters are energised.
The heater power circuit must be interlocked with the drive to ensure that power to the heater is
removed when the motor is running.
8. GENERAL INSPECTION & MAINTENANCE
!! WARNING !!
!! ELECTRICITY CAN KILL !!
All work on electrical installations should be closely controlled and a “Permit to Work” system
is highly recommended along with a “Lockout” procedure according to Local and/or National
standards.
Do not touch cables unless it is known to be safe!
Beware of rotating shafts: Secure any loose clothing etc!
Do not use cleaning solvents in confined spaces without adequate ventilation!
!! Important Note !!
The inspection and maintenance of this machine shall be performed by experienced
personnel, whose training has included instruction on various types of protection and
installation practices, the relevant rules and regulations and on general principles of area
classification.
This machine is intended for use in Potentially Explosive Atmospheres, Zone I, Group IIC
and as such, we recommend that for any overhaul or repair work, the machine be returned to
Oilfield Electric Marine to ensure that the „Increased Safety‟ protection concept to the
applicable standards is maintained.
Any repair arranged by the end user, unless expressly approved by manufacturer, releases the
manufacturer from his responsibility to conformity.
REV 00 Page 11 of 18
Inspection and Maintenance
Check the motor at regular intervals and develop an inspection/maintenance routine. The
following minimum requirements must be met.
Weekly: Visual Inspection.
An inspection which identifies, without the use of tools or accessing the equipment, those defects
such as loose bolts or covers, cable insulation and ground connection which are apparent to the
eye. Check that air flow is sufficient and that there are no obstructions to the intake and exhaust
vents of the motor and blower. Check the motor bearings for signs of overheating, discoloration,
excessive vibration and abnormal noise.
Monthly: Close Inspection.
With the machine safely switched of and locked out, inspect physically and tighten any loose
bolts, covers and guards.
6 Monthly: Detailed Inspection.
With the machine safely switched off and locked out, check for loose terminations, where
accessible and without removing insulated connections unless they are obviously in need of
attention.
Check the condition of shaft seals and replace if necessary.
Bearing condition can be checked by listening for excessive noise, inspection of used grease,
observing/monitoring bearing temperatures or measurement of vibration.
Add grease to the bearings. (2oz per bearing)
Replace the bearings every 25,000 hours of use.
Check the insulation resistance to ground (earth) and between phases with the motor leads
disconnected from the drive. Use motor heaters if insulation resistance to ground is below 1
megohm.
In no instance must the motor design be modified.
If the motor needs to be rewound, this may only be carried out by the manufacturer or nominated
representative. Failure to do so will invalidate the certification and warranty and could
compromise design features that affect the conformity to the specifications.
REV 00 Page 12 of 18
9. HUB REMOVAL
To remove the hub, always use a hydraulic pump assembly which is specially designed for this
purpose. Such as, an Enerpac Test Pump, (SEE CHART BELOW) capable of producing 40,000
psi.
Contact OEM for details of this pump or similar models.
This is simple, yet leaves the motor shaft in perfect condition and ready for reinstallation of the
hub after bearings have been changed. There is no need to use “Strong Back” type pullers and
heat Should Not Be Applied with this method.
To remove the hub:
i) Clean the end of the shaft inside the hub and remove the small plus in the
end of the shaft using the appropriate sized Allen wrench.
ii) Fit the knurled nut onto the threads of the shaft and make up all the way.
Then back off the nut until the hole in the shaft is visible and accessible.
iii) Fit the pump adapter into the shaft hole and tighten all the way. Insert the
pump tube extension and attach the pump. Ensure that the pump is placed
safely onto a raised block in line with the shaft to prevent bending the
tubing.
iv) Close the pump valve and apply pressure until it becomes difficult to
apply any more pressure. Then, pump the handle a couple of times and
the hub will break loose. The hub will not fall off the shaft as the knurled
nut will prevent this.
v) Open the pump valve and remove all fittings. Close the pump valve again
and stow all of the tools used for hub removal.
vi) Reinsert the Allen screw into the end of the shaft, loosely until the hub is
to be replaced onto the shaft.
vii) NOTE: When reinstalling the hub, be sure to remove the Allen screw
before fitting the heated hub onto the shaft. Then, after the hub and
shaft have cooled, replace the screw into the end of the shaft and
tighten so that it is a snug fit. Do not over tighten this screw!
