Insulation resistance check (earth-
ing)
The insulation of industrial trucks should have
sufficient insulation resistance. Test the truck
and battery separately.

electrical system
Have the insulation re
sistance of all active
electrical compone
nts checked in accordance

N 43539, VDE 0117
and VDE 0520.
Measurement voltage > nominal voltage <
500 V. Insulation is considered correct when
it is measured in relation to the chassis and is
higher than 1000 ohm/V of nominal voltage.
