5.2 Converting the single-phase transformer T1 from 230 VAC to 110 VAC
Å Disconnect the black wire from terminal 6 (230 V) and connect it to terminal 4 (120 V - see Fig.
5 - 2).
5.3 Converting the three-phase transformer T2 from 3 x 400 VAC to 3 x 208 VAC
Å Disconnect the black wire from terminal 1 (400 V) and connect it to terminal 7 (208 V) (see Fig.
5 - 2).
Å Disconnect the black wire from terminal 2 (400 V) and connect it to terminal 8 (208 V) (see Fig.
5 - 2).
Å Disconnect the black wire from terminal 3 (400 V) and connect it to terminal 9 (208 V) (see Fig.
5 - 2).
5.4 Converting the inrush current limiter A1 from 3x400 VAC to 3x208 VAC
Å Disconnect wire 3 from terminal 13 and connect it to terminal 14 (see Fig. 5 - 3).
Å Disconnect wire 6 from terminal 23 and connect it to terminal 24 (see Fig. 5 - 3).
Å Disconnect wire 9 from terminal 33 and connect it to terminal 34 (see Fig. 5 - 3).
Å Disconnect wire 2 from terminal 12 and connect it to terminal 13 (see Fig. 5 - 3).
Å Disconnect wire 5 from terminal 22 and connect it to terminal 23 (see Fig. 5 - 3).
Å Disconnect wire 8 from terminal 32 and connect it to terminal 33 (see Fig. 5 - 3).
5.5 Installing the power supply unit
Å Carefully push the power supply unit into the housing until it reaches the stop.
Å Secure the unit to the bottom part using the hexagon socket-head screw.
Å Check that the yellow-green protective earth conductor is connected to the cover.
Å Attach 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
Å Fix the cover in place using the two hexagon socket-head screws.
