Relative Humidity: 70% (no condensation)

Altitude: < 2000m

Temperature: 0C~40C

(Pollution Degree) EN 61010-1:2010 specifies the pollution degreesand their requirements as follows. The GPT-9000 falls under degree2.

Pollution refers to addition of foreign matter, solid, liquid, orgaseous (ionized gases), that may produce a reduction of dielectricstrength or surface resistivity.

Pollution degree 1: No pollution or only dry, non-conductivepollution occurs. The pollution has no influence.

Pollution degree 2: Normally only non-conductive pollutionoccurs. Occasionally, however, a temporary conductivity causedby condensation must be expected.

Pollution degree 3: Conductive pollution occurs, or dry, non-conductive pollution occurs which becomes conductive due tocondensation which is expected. In such conditions, equipmentis normally protected against exposure to direct sunlight,precipitation, and full wind pressure, but neither temperaturenor humidity is controlled.

Power cord for the United Kingdom

When using the safety tester in the United Kingdom, make sure the

power cord meets the following safety instructions.

NOTE: This lead/appliance must only be wired by competent persons

WARNING: THIS APPLIANCE MUST BE EARTHEDIMPORTANT: The wires in this lead are coloured in accordance with thefollowing code:Green/ Yellow: EarthBlue: NeutralBrown: Live (Phase)

As the colours of the wires in main leads may not correspond withthe coloured marking identified in your plug/appliance, proceedas follows:

The wire which is coloured Green & Yellow must be connected tothe Earth terminal marked with either the letter E, the earth symbol

or coloured Green/Green & Yellow.

The wire which is coloured Blue must be connected to the terminal

which is marked with the letter N or coloured Blue or Black.The wire which is coloured Brown must be connected to theterminal marked with the letter L or P or coloured Brown or Red.

If in doubt, consult the instructions provided with the equipmentor contact the supplier.

This cable/appliance should be protected by a suitably rated andapproved HBC mains fuse: refer to the rating information on the

equipment and/or user instructions for details. As a guide, a cableof 0.75mm2should be protected by a 3A or 5A fuse. Largerconductors would normally require 13A types, depending on theconnection method used.

Any exposed wiring from a cable, plug or connection that isengaged in a live socket is extremely hazardous. If a cable or plug isdeemed hazardous, turn off the mains power and remove the cable,any fuses and fuse assemblies. All hazardous wiring must beimmediately destroyed and replaced in accordance to the abovestandard.

Operating Precautions

Background The GPT-9000 is a high voltage instrument thatoutputs dangerous voltages. The followingsection describes precautions and proceduresthat must be followed to ensure that the testeris operated in a safe manner.

WARNINGThe GPT-9000 generates voltages of up to 5kVACor 6kVDC. Follow all safety precautions, warningsand directions given in the following section when

using the GPT-9000.

1. Never touch the safety tester, lead wires,terminals, probes and other connectedequipment when the tester is testing.

2. Do not turn the safety tester on and off quicklyor repeatedly. When turning the power off,

please allow a few moments before turning thepower back on. This will allow the protectioncircuits to properly initialize.

Do not turn the power off when a test isrunning, unless in an emergency.

3. Only use those test leads supplied with theinstrument. Leads with inappropriate gaugescan be dangerous to both the operator and theinstrument.For GB testing, never use the Sense leads on theSOURCE terminals.

4. Do not short the HIGH VOLTAGE terminalwith ground. Doing so could charge the chassisto dangerously high voltages.


25/149

GETTING STARTED

25

5. Ensure the earth ground of the line voltage isproperly grounded.

6. Only connect the test leads to the HIGHVOLTAGE/SOURCE H/SENSE H terminalsbefore the start of a test. Keep the test leadsdisconnected at all other times.

7. Always press the STOP button when pausingtesting.

8.

Do not leave the safety tester unattended.Always turn the power off when leaving thetesting area.

9. When remotely controlling the safety tester,ensure adequate safety measures are in place toprevent:

Inadvertent output of the test voltage.

Accidental contact with the instrument duringtesting. Ensure that the instrument and DUT arefully isolated when the instrument is remotelycontrolled.

10.Ensure an adequate discharge time for theDUT.

When DCW or IR tests are performed, the DUT,test leads and probes become highly charged.The GPT-9000 has discharge circuitry todischarge the DUT after each test. The timerequired for a DUT to discharge is typically200ms.

Never disconnect the safety tester before a

discharge is completed.


26/149


26

Basic Safety Checks

Background The GPT-9000 is a high voltage device and assuch, daily safety checks should be made toensure safe operation.

1. Ensure all test leads are not broken and are freefrom defects such as cracks or splitting.

2. Ensure the safety tester is always connected to

an earth ground.

3. Test the safety tester operation with a lowvoltage/current output:

Ensure the safety tester generates a FAILjudgment when the HIGH VOLTAGE andRETURN terminals are shorted (using thelowest voltage/current as the testingparameters).

WARNINGDo not use high voltages/currents when the HIGHVOLTAGE and RETURN terminals are shorted. Itmay result in damage to the instrument.

Setting the Grounding Mode

Background When GROUND MODE is set to ON, the GPT-9000 grounds the return terminal to the ground.This mode is best for DUTs that are groundedto an earth ground by their chassis, fixtures oroperation environment. This mode measuresthe potential of the HIGH VOLTAGE terminalwith respect to earth ground. This means thatany stray capacitance/resistance that leaks to

earth ground will also be measured. This is thesafest testing mode, though potentially not asaccurate.

When GROUND MODE is set to OFF, thereturn terminal is floating with respect to theearth ground. This mode is for DUTs that arefloating and not directly connected to an earthground. This is more accurate than when

GROUND MODE is set to ON as any straycapacitance/resistance that leaks to the earthground from the DUT side of the testing circuitwill not be measured. For this reason, thistesting mode is able to measure to a higheraccuracy and resolution.

The GROUND MODE is always set to OFF for

IR and GB tests.
