8.2.2 Main Circuit Insulation Test
Before measuring the insulating resistance with megameter (500 VDC megameter
recommended), disconnect the main circuit cables from the controller. Do not use the
insulating resistance meter to test the insulation of the control circuit.
The high voltage test need not be performed again because it has been completed
before delivery.
