208 or 230 Mode
The PowerCut 900, 208/230 vac, 60 Hz model, is factory set for 230 vac input. If using 208 vac input, the PowerCut
900 must be reconnected as follows before connecting to your input power:
1. Remove cover.
2. Locate the Output Diode Bridge (D101) (see Figure 3.2A) on the left side towards the front panel. Disconnect
and exchange the X2 and X3 leads only. Leave other smaller wire in place. For 208 vac input, X2 is connected to
D101-2 and X3 is connected to D101-3. Ensure the connections are firmly tightened to 22 in/lbs (2.5 Nm).
3. Locate the J27 Control Supply Voltage jumper plug (violet wire) on left side towards the rear panel (see Figure
3.2b). Remove the cover plug from the J23 (208 V) header. Move J27 jumper from J20 (230 V) to J23 (208 V).
Place the cover plug on the J20 (230 V) header.
4. Reinstall cover and connect the PowerCut 900 to 208 vac input power.
