Hazardous zones of the machine may only be entered by designated and authorised
persons!
If several persons are working on the machine, good cooperation and close
coordination of the activities is necessary.
Electrical energy
a)
Use only original fuses with the prescribed amperage! In the event of faults in
the electric power supply, switch off the machine immediately!
b)
Work on electrical installations or equipment may only be carried out by an
electrician or by trained persons under the instruction and supervision of an
electrician.
c)
Parts of machines and installations on which inspection, maintenance and
repair work is being carried out on the electrical equipment must – if prescribed
– be isolated and secured to prevent restarting. First check that the isolated
parts are no longer live, then earth and short-circuit and isolate adjacent live
parts
d)
The electrical equipment of the machine must be inspected and checked at
regular intervals. Faults such as loose connections or scorched cables must be
remedied immediately.

If work is necessary on live parts, have a second person standing by who can
turn off the master switch or emergency stop switch in the event of an
emergency. Cordon off the working area with a red/white safety chain and a

a ground rod.
