Electrical insulation testing
The truck's electrical insulation must have suf-
ficient insulation resistance. Insulation resist-
ance must be tested in accordance with EN
1175–1 and ISO 20898 at least once a year.
NOTE
The truck's electrical system and drive batter-
ies must be checked separately.
Measuring battery insulation resistance
NOTE
●
Test voltage > battery nominal voltage
●
The test voltage must not exceed 100 V or
triple the value of the nominal voltage
– Measure insulation resistance using a suita-
ble meter.
The insulation resistance is sufficient when it
has a resistance of at least 50 Ohms multi-
plied by the nominal voltage of the truck cir-
cuit, between the parts under voltage and the
truck chassis.

The insulation resistance is sufficient when it
has a resistance of at least 1000 Ohms multi-
