8.5.7 Reconnecting the inrush current limiter board

The inrush current limiter board is located on the back of the front panel (see item EST in Fig. 8 -

4, page 264.

 Reconnect the following wires (see Fig. 8 - 6, page 266):

(W) from terminal X13 to terminal X14,

(V) from terminal X23 to terminal X24 and

(U) from terminal X33 to terminal X34.

 Move the following jumpers:

B3 from terminal X12 to terminal X13

B2 from terminal X22 to terminal X23 and

B1 from terminal X32 to terminal X33.

8.5.8 Installing the power supply unit

 Carefully push the power supply unit into the housing until it reaches the stop.

 Use the M8 hexagon socket-head screw to secure the unit at the bottom.

 Check that the yellow-green PEwire is connected to the door.

 Close the door.

PLEASE NOTE: 8

Make sure that the actuating shaft of the main switch slides easily into the opening in the ro-

tary button. 8

 Use the machine key to lock the door.

RISK OF DEATH 8

 Disconnect the machine correctly as described in section 1, page 145.

 Disconnect the machine from the main power supply.

 Take suitable action to ensure that the machine cannot be connected to the power supply dur-

ing the conversion work.

 Put up warning signs to indicate that work is being carried out on the electrical system.
