2.6 Safety whilst working on the electrics
If there are
faults on the electrical system
of the machine, it must be
shut down immediately using the main switch and secured with a lock
or the mains plug must be removed!
Work on the electrical equipment of the machine must only be carried
out by qualified electricians working in accordance to electrical
engineering regulations! Only professional electricians may access the
machine's electrics and carry out work on it.
Always keep the switch
boxes closed as soon as they are left unattended.
Never work on live parts! System parts on which inspection,
maintenance or repair work is to be carried out must be
disconnected from the mains . Operating fluids that have been
disconnected must be secured against being switched back on
unintentionally or automatically (lock away fuses, block isolating
switches, etc.). The disconnected, electrical components must first be
tested to ensure they are voltage-free, then earthed, short-circuited and
isolated from neighbouring live components.
If tasks must be carried out on live components (only in exceptional
circumstances) an
additional person
must be present to operate the
EMERGENCY STOP button or main switch in the event of an
emergency. Only use insulated tools!
When carrying out repairs, make sure that safety design features are
not changed (e.g. creeping distances, clearances and distances must
not be made smaller by insulation).
Fault-free earthing of the electrical system must be ensured by
a protective earth system .
