SAFETY
The
machine must always
be at a standstill before commenc-
ing any
maintenance
or repair work.
The machine
must
always be disconnected from the mains
before commencing
repair
or
maintenance work. For this, the
main switch on the switchgear cabinet must be turned
off
(position
0)
and
secured
with
a
padlock.
The member
of staff
responsible for this work must take
possession
of the
key to
this
padlock.
The electrical supply line from the mains to the
switchgear
cabinet
must also be disabled before
starting work inside the
switchgear cabinet, Care must be taken to
ensure that
the
main
supply line
cannot be activated during work. The re-
sponsible member of staff must satisfy himself, with
a
meas-
uring
instrument,
that the supply line is really dead
prior
to
starting
work.
Furthermore,
additional measures, such as
preventing
access
to
unauthorized
personnel,
are absolutely necessary.
lf
it is necessary to remove any
protective
devices
for repair
or
maintenance work, these may
only be
removed

protective
dev-
ices
must be replaced immediately
after repairwork has been
completed.
The machine may
only be reconnected to the mains
when
all
protective
devices have
been installed and activated.
The switchgear cabinet may only be
opened when the main
switch
has been
turned off

Once electrical installation
or repair work has been
carried
out, the fitted
protective
devices must
be tested by an
authorized
electrician
(e.9.
grounding
resistance).
Adjustment or setting work may only be carried
out on the
machine when it is switched
off
-
