The main switch must be switched on.
With nominal (DC) battery charging system voltages 500 V the test voltage of the
measuring equipment is 500 V for all measurements *).
The insulation resistance must not fall below the following values *):
Legend:
Primary = AC (L1, L2, L3 and N) | Secondary = DC (DC+ and DC-)
Earth = PE | Communication = USB
*) These requirements comply with DIN VDE 0701-0702 and ÖVE/ÖNORM E8701-1. Also
refer to the applicable requirements and standards in your country.
The insulation measurement must be taken between the following points:
DC+ and DC- should be short-circuited for this test on the battery charging system, other-
wise both DC inputs have to be measured separately.
N and L1, L2, L3 should be short-circuited for this test on the battery charging system, oth-
erwise both AC inputs have to be measured separately.
Use an adapter to short-circuit DC+ / DC- / AC / Communication and optional inputs during
this measurement
Only use the original charger leads and mains cable for taking the measurements.
