Testing the electrical system
DANGER
Risk of explosion!
Trucks to be used in potentially explo-
sive areas are designed for certain ex-
plosion groups, categories and tempera-
ture ranges. In potentially explosive
areas, trucks that do not meet explosion-
protection regulations may lead to explo-
sions in the surrounding atmosphere.
–
Only use trucks with an electrical sys-
tem that complies with the valid ex-
plosion protection directives.
–
The proper condition of the electrical
system of trucks used in potentially
explosive areas must be monitored
continuously by a competent person.
–
Observe the explosion-protection reg-
ulations.
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 sys-
tem 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 ta-
bles.
–
For insulation testing, contact the author-
ised service centre.
The exact procedure for this insulation testing
is described in the workshop manual for this
truck.
