Safety when working on the electric system
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
padlock or the mains plug must be disconnected!
Work on the electrical equipment of the machine must only be carried
out by
qualified electricians
working in accordance with electrical
engineering regulations! Only professional electricians may access the
electrical system of the machine and carry out work on them.
Always
keep the switch boxes closed
whenever 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 power
.
Operating equipment that has 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 have to 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. Use only insulated tools!
During repairs, ensure 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 reduced by insulation).
Fault-free
earthing
of the electrical system must be ensured by a
protective earth system
.
