7 Maintenance
Checking/replacing the fuses on the road traffic module
Accident hazard due to high electrical voltages!
Improper performance of work on the electrical system can result in
serious injury or death.
► Maintenance that does not involve HV components (e.g. replacing
fuses), where the maintenance personnel must work near HV
components and, in the event of an error, could trigger an electrical
hazard, must be performed by "electrically trained persons". The
training must include the following factual information:
- the hazard sources on the machine,
- safety measures and
- the corresponding rules of conduct.
► In order to be permitted to perform maintenance on HV systems of the
machine, further training as "Expert for Work on HV Intrinsically Safe
Machines" (DGUV Information 200-005) is mandated in Germany.
Be aware of, observe and comply with the corresponding legal
regulations of other countries.
Defective fuses of the fuse box A are indicated by the diagnostic LED
5H18 by a flash code
– see chapter 8 “Fault indications in the StVZO module” on page 8-38.
