Fig.60: Unplugging electrical connections
► Unplug all electrical connections between
the contactor safety breaker(1)
and the
distribution and fusing board(2)
. You
might like to mark their positions to make
clear assignment easier later on.
Fig.61: Removing the contactor circuit breaker
► Loosen the screw(1) on the rear of the
contactor safety breaker.
To access the screw, route an extension
past the side of the contactor safety
breaker.
► Lift the contactor safety breaker up a bit.
► Unplug the electrical connections
between the contactor safety breaker and
the buffer module (2)
.
► Lift the contactor safety breaker off.
Installation
Follow the removal instructions in reverse order for installation. Also observe the following instructions:
► Make sure that the cables are run correctly.
► The cables must not be pinched or rub against unprotected edges.
► Make sure that the cables are only run out of the contactor safety breaker through the two re-
cessesprovided.

DANGER
Checking for absence of voltage!
► Before you start working check the power supply for absence of voltage and observe
the waiting times! For more information about this read section 3.4.3
"Checking For
Absence of Voltage" [}49].
► When replacing the AC/DC converter (PS5) fitted at the side:
Pull the power supply out of the machine a little.
► Unplug all electrical connections from the AC/DC converter. You may want to mark the posi-
tions of these connections to make clear assignment easier later on.
► Open the lock under the AC/DC converter. Tilt the AC/DC converter slightly upwards and then
take it up and off.
Installation
Follow the removal instructions in reverse order for installation. Also observe the following instruc-
tions:
► Set the AC/DC converter (see 3.4.7 "Setting the Voltage on the AC/DC Converters" [}59]).

correct voltage on the AC/DC con-
verter.
Check the voltage with a suitable
voltage measuring device between the
terminals +
and–.
