- -Ve PL18W-201-35
The test box has the following test points incorporated:
- 1000V CAT III test points for a Voltage check using RS PRO RS-9331 1000V Voltage Tester
- 1000V CAT III 4mm banana socket test points for an Insulation Test using a Fluke 1587 Insulation Multimeter.
- 5000V CAT 0 4mm banana sockets and W-5600H05-100-0 test lead for an HiPot test using a Seaward HAL103 HiPot tester.
- Blanking plugs are provided for the Voltage and Insulation Test Points to be used when not in direct use.

General User Instructions:
Conducting electrical tests:
Before starting, ensure all blanking plugs are fitted to the test box and place on a flat surface. Then connect the EV connectors to the battery connection points.
Voltage Test:
- Remove the voltage test point blanking plugs.
- Noting the correct polarity insert the voltage tester probe tips in to the voltage test points until you feel the tips reach the internal test points.
- Conduct the voltage test using the voltage tester.
- Once the voltage test is complete, remove the probe tips and replace blanking plugs.


Insulation Test:
- Remove the tip cover from the insulation test probe so that it exposes the lantern tip.
- Remove the +Ve insulation Test Point blanking plug.
- Insert the insulation test probe lantern tip into the +Ve Insulation Test Point.
- Conduct the +Ve Insulation Test.
- Once the test is complete, remove the test probe and replace the blanking plug.
- Remove the -Ve Insulation Test Point blanking plug.
- Insert the insulation test probe lantern tip into the +Ve Insulation Test Point.
- Conduct the -Ve Insulation Test.
- Once the test is complete, remove the test probe and replace the blanking plug.

HiPot Test:
- Ensure all blanking plugs are fitted to the voltage and insulation test points.
- Connect the W-5600H05-100-0 4mm Banana Plug to Seaward HAL Tester Test lead to the HAL 103.
- Insert the test lead banana plug into the +Ve test point and conduct the HiPot test.
- Once the test is complete, remove the banana plug and insert into the -Ve test point.
- Conduct the -VE HiPot test.
- Once complete, remove the 4mm banana plug lead.
