Testing the electrical system
DANGER
Risk of explosion!
Trucks to be used in potentially ex-
plosive areas are designed for certain
explosion groups, categories and
temperature ranges. In potentially ex-
plosive areas, trucks that do not meet
explosion-protection regulations may
lead to explosions in the surrounding
atmosphere.
– Only use trucks with an electrical
system that complies with the valid
explosion protection directives.
– The proper condition of the elec-
trical system of trucks used in po-
tentially explosive areas must be
monitored continuously by a com-
petent person.
– Observe the explosion-protection
regulations.
The scope of the checks is described in the
"workshop manual".
A test log book is to be kept if requested by the
responsible authority.
– Only a competent person may perform
system testing.
– Observe the national regulations for the
country in which the truck is being used.
Insulation testing
The insulation of the truck must have sufficient
insulation resistance. For this reason, insula-
tion testing in accordance with DIN EN 1175
and DIN 43539, VDE 0117 and VDE 0510
must be conducted at least once yearly as part
of the FEM testing.
The insulation testing results must be at least
the test values given in the following two
tables.
– For insulation testing, contact the autho-
rised service centre.
