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 work on live components is required (only in exceptional
circumstances) an additional person must be called who can operate
the EMERGENCY STOP button or main switch in the event of an
emergency. Only use insulated tools!
During repairs, make sure that design features are not modified so
that they have a negative influence on safety. (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.
