2.2 Unloading and installation2.2.1 Transport unitsThe transport units consist of up to three double panels which are assembled including the busbars and the associated withdrawable units.In transport units consisting of one double panel the busbar and branch busbar are packed separately in the busbar compartment and fixed on the partition plate to the cable termination compartment.

2.2.2 PackingAs specified in the order:a) Each transport units is screwed to a sturdy wooden pallet

and covered by plastic sheeting as a protection against rain and dust.

b) For oversea shipment, each transport unit is packed seaworthy in a crate.. i.e. enclosed in a plastic sheeting which is sealed air-tight and includes bags containing a dessicant. The HV fuses and accessories are transported in separate packing.

2.2.3 UnloadingLifting equipment required:• A mobile crane for unloading the transport units.• Lifting tackle.• A lifting truck or a fork lift with a fork length of approx 1.5 m for handing the switchgear inside the building.• Hydraulic jacks or winches and roller pads.• The handing/transport gear must meet the site

requirements with regard to its construction and load bearing capacity. Make reference to the weights (for raising and transporting) given on the transport units or in the covering documents.

Proceed as follows:• Unload the transport units in their packing.• Take care not to damage the plastic sheeting.Unloading by mobile crane:• Suspend the lifting tackle from the crane and position it

over the transport unit.• Attach the ropes to the tackle and position them so that

they cannot exert pressure on the switchpanel sides.• Sling the ropes round the ends of the wooden pallet.• Carefully lift the unit and check whether it has been

correctly balanced. If necessary, lower the unit and rebalance.

Unloading by means of a fork lift:• Observe uniform distribution of weight– Move the transport units as close as possible to the

switchgear building and put them down.– Dismantle and remove the crates (if provided).– Move the transport units into the building.– The plastic sheeting should only be removed in the building

shortly before the units are assembled and temporarily to check them for signs of transport damage.

– In the latter case roll the units to their installation site. If this means changing the direction of travel, lift the units and relocate the roller pads accordingly observing the floor cutouts. When the site of installation has been reached, lift the transport units by four winches and remove the roller pads. Then lower the units as far as possible and put them down on two wooden beams.

– Now lift the units, first on one side and then on the other using roller-type crowbars. Then withdraw the wooden supporting beams before putting down and aligning the units on the cleaned foundation.

Note! Apply the roller-type crowbars only at the corners of the units below the vertical frame members!

2.2.6 Installation of switchpanelsCarry out the work in the sequence described under 2.2.6.1 to 2.2.6.4

2.2.6.1 Bolting the panels togetherIt is assumed that the first transport unit is in its final position and that the other units are arranged beside with clearances between them and in the correct sequence.

Procedure:• Align the first transport unit on its foundation. The

panels must be at the correct level (see dimension drawing, Fig.7), arranged vertically and so aligned that the door mark lies within the upright mark (Fig.8)

Note! Do not readjust the door hinges and locking elements.If necessary, place shims– Under the corners of the panels and– Under the baseframes near the 45mm×25mm cutouts

provided for the foundation bolts.

• Screw off the bolts for bolting the panels together. (Fig.9)• Carefully move up the second/next transport unit to the

aligned unit.• Align the moved up transport unit at the site of

installation as the first unit.

2.2.4 Checking for damage in transitImmediately after unloading and unpacking check the switchgear for completeness and damage. Record any damage and its cause without delay and in the presence of the forwarding agent if the damage was caused in transit. The record is essential if claims for damages should be raised.

2.2.5 Moving the transport units to installation place• Move the transport units including their wooden pallets:– To their point of installation in the switchgear building

using a lifting tuck, a fork-lift truck or rollers.– Put them down on the cleaned site of installation or at

least directly in front of it in the correct order and with a certain clearance between them.

• To remove the transport units from their wooden pallets:– Move the withdrawable units from the service position

(as-supplied state) to the disconnected position and open the switchgear compartment doors.

Insert the double-bit key Type 5 to DIN 43 668-C35 into lock 10(Fig.14) and turn it anti-clockwise by 90˚.

Raise the catch(11,Fig.14)to the stop and awing up to the door.

– Remove the withdrawable units and store them in a clean dust-free room.

• Caution! As the transport units are still placed on their wooden pallets they must be lifted out.

(see Section 3.4.1.2) – Undo the bolts in the front bottom range (inside)by

means of which the switchpanels are fixed to the wooden pallets and remove the transport angles (outside). The front bolts are located behind the door of the left-hand withdrawable unit compartment in the front cross member.

– Close the doors of the withdrawable unit compartments. (Refer to Section 3.3.1)

Example– Pull out two planks with blackened ends from one of the

outer switchpanels. The floor rails are now accessible at four points.

– Slide two channels of sufficient carrying capacity under the panel whilst lifting the transport units with a crowbar if necessary. The channel must project by approx. 250mm on both sides of the wooden pallet.

– Apply four winches to the projecting ends of the channels and lift the transport units uniformly.

– Remove the wooden pallet.– Lower the transport unit as far as possible and put it

down on two wooden beams when it is located above the site of installation or put the unit down on four roller pads when it is located in front of the installation site.

2.2.6.1 Bolting the panels togetherIt is assumed that the first transport unit is in its final position and that the other units are arranged beside with clearances between them and in the correct sequence.

Procedure:• Align the first transport unit on its foundation. The

panels must be at the correct level (see dimension drawing, Fig.7), arranged vertically and so aligned that the door mark lies within the upright mark (Fig.8)

Note! Do not readjust the door hinges and locking elements.If necessary, place shims– Under the corners of the panels and– Under the baseframes near the 45mm×25mm cutouts

provided for the foundation bolts.

• Screw off the bolts for bolting the panels together. (Fig.9)• Carefully move up the second/next transport unit to the

aligned unit.• Align the moved up transport unit at the site of

installation as the first unit.

2.2.4 Checking for damage in transitImmediately after unloading and unpacking check the switchgear for completeness and damage. Record any damage and its cause without delay and in the presence of the forwarding agent if the damage was caused in transit. The record is essential if claims for damages should be raised.

2.2.5 Moving the transport units to installation place• Move the transport units including their wooden pallets:– To their point of installation in the switchgear building

using a lifting tuck, a fork-lift truck or rollers.– Put them down on the cleaned site of installation or at

least directly in front of it in the correct order and with a certain clearance between them.

• To remove the transport units from their wooden pallets:– Move the withdrawable units from the service position

(as-supplied state) to the disconnected position and open the switchgear compartment doors.

Insert the double-bit key Type 5 to DIN 43 668-C35 into lock 10(Fig.14) and turn it anti-clockwise by 90˚.

Raise the catch(11,Fig.14)to the stop and awing up to the door.

– Remove the withdrawable units and store them in a clean dust-free room.

• Caution! As the transport units are still placed on their wooden pallets they must be lifted out.

(see Section 3.4.1.2) – Undo the bolts in the front bottom range (inside)by

means of which the switchpanels are fixed to the wooden pallets and remove the transport angles (outside). The front bolts are located behind the door of the left-hand withdrawable unit compartment in the front cross member.

– Close the doors of the withdrawable unit compartments. (Refer to Section 3.3.1)

Example– Pull out two planks with blackened ends from one of the

outer switchpanels. The floor rails are now accessible at four points.

– Slide two channels of sufficient carrying capacity under the panel whilst lifting the transport units with a crowbar if necessary. The channel must project by approx. 250mm on both sides of the wooden pallet.

– Apply four winches to the projecting ends of the channels and lift the transport units uniformly.

– Remove the wooden pallet.– Lower the transport unit as far as possible and put it

down on two wooden beams when it is located above the site of installation or put the unit down on four roller pads when it is located in front of the installation site.
