Safety tests
Electrical insulation testing
The truck's electrical insulation must have
sufficient insulation resistance. Insulation
resistance 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 batte-
ries 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
suitable meter.
The insulation resistance is sufficient when it
has a resistance of at least 50 Ohms multiplied
by the nominal voltage of the truck circuit,
between the parts under voltage and the truck
chassis.

Measuring the insulation resistance of
the electrical system
NOTE
•
Test voltage > battery nominal voltage
•
The test voltage must not exceed 100 V or
triple the value of the nominal voltage
– Measure insulation res
istance using a
suitable meter.
The insulation resistance is sufficient when
it has a resistance of at least 1000 Ohms
multiplied by the nominal voltage of the truck
circuit, between the parts under voltage and
the truck chassis.
