3.5.2 Converting the single-phase transformer T1 from 230 VAC to 110 VAC
Å Detach the black connecting wire from terminal h (230 V) and connect it to terminal f (120 V
- see Fig. 3 - 2
).
3.5.3 Converting the three-phase transformer T1 from 3 x 400 VAC to 3 x 208 VAC
Å Detach the black connecting wire from terminal a (400 V) and connect it to terminal j (208 V)
see Fig. 3 - 2
).
Å Detach the black connecting wire from terminal s (400 V) and connect it to terminal k (208 V)
see Fig. 3 - 2
).
Å Detach the black connecting wire from terminal d (400 V) and connect it to terminal l (208 V)
see Fig. 3 - 2
).
3.5.4 Converting the inrush current limiter A1 from 3x400 VAC to 3x208 VAC
Å Detach wire d from terminal 13 and connect to terminal 14 (see Fig. 3 - 3).
Å Detach wire h from terminal 23 and connect to terminal 24 (see Fig. 3 - 3).
Å Detach wire l from terminal 33 and connect to terminal 34 (see Fig. 3 - 3).
Å Detach wire s from terminal 12 and connect to terminal 13 (see Fig. 3 - 3).
Å Detach wire g from terminal 22 and connect to terminal 23 (see Fig. 3 - 3).
Å Detach wire k from terminal 32 and connect to terminal 33 (see Fig. 3 - 3).
3.5.5 Installing the power supply unit
Å Carefully push the power supply unit into the housing until it reaches the stop.
Å Use the hexagon socket-head screw to secure the unit at the bottom.
Å Check that the yellow-green PE wire is connected to the cover.
Å Replace the cover.
PLEASE NOTE: 3
Make sure that the actuating shaft of the main switch slides easily into the opening in the
rotary button. 3
Å Fix the cover in place using the two hexagon socket head screws.
