(400 VAC) (see Fig. 5 - 9
).
Detach the black connecting wire from terminal 1 W3 (208 VAC) and connect to terminal 1W1
(400 VAC) (see Fig. 5 - 9
).
5.8.4 Converting the inrush current limiter A1 from 3 x 208 VAC to 3 x 400 VAC
Detach wire (3) from terminal 14 and connect to terminal 13 (see Fig. 5 - 10).
Detach wire (6) from terminal 24 and connect to terminal 23 (see Fig. 5 - 10).
Detach wire (9) from terminal 34 and connect to terminal 33 (see Fig. 5 - 10).

5.8.5 Installing the power supply unit
Carefully push the power supply unit into the housing until it reaches the stop.
Use the hexagon socket-head screw to secure the unit at the bottom.
Check that the yellow-green PE wire is connected to the cover.
Replace the cover.
PLEASE NOTE: 5
Make sure that the actuating shaft of the main switch slides easily into the opening in the ro-
tary button. 5
Fix the cover in place using the two hexagon socket head screws.

5.8.6 5 or 4-wire connection for the power supply
The connections are produced using either 5 or 4 wires, according to the electricity company's re-
quirements (see Section 5.6.6
, page 197). 5
5.8.7 Remove the socket guard from the X1 service socket.
For the European system, remove the socket guard from service socket X1.
5.8.8 Carry out the safety check to DIN EN 60 204
When the conversion is complete, carry out a safety check to DIN EN 60 204.
Follow the procedure described in section 2, page 146 onwards.
