Connecting the braking resistor
WARNING
Fire caused by ground fault / short-circuit for non-protected connections to the braking
resistor
Non-fused connections to the braking resistor can cause fire with smoke generation in the
event of a short-circuit or ground fault and cause serious injuries or death.
•
Install the connections to the braking resistor in such a way that a ground fault or short-
circuit can be excluded.
•
Comply with local installation regulations, which allow this fault to be ruled out.
•
Protect the cables from mechanical damage.
•
Take one of the following measures:
–
Use cables with double insulation.
–
Observe adequate clearances, e.g. through the use of spacers.
–
Route the cables in separate cable ducts or pipes.
