Before making any connections to the

power source output terminals, make sure

that all primary input power to the power

source is deenergized (o) at the main

disconnect switch and that the input power

cable is unplugged.

ELECTRIC SHOCK CAN KILL! Precautionary

measures should be taken to provide maxi-

mum protection against electrical shock.

Be sure that all power is o by opening

the line (wall) disconnect switch and by

unplugging the power cord to the unit

when reconnecting for 208 Vac input.

3.4.2 CONNECTING POWERCUT 650 FOR 208 vac INPUT

The Powercut 650 power source with 208/230 vac, single phase input capability

is factory set for 230 vac input. If using 208 vac input, the Powercut 650 must be

reconnected as follows before connecting to 208 vac input power.

1. Unplug the unit from the primary input power.

2. Remove the left side panel by removing the front handle and sliding the cover

forward from the aluminum frame rail.

3. Locate the input bridge (IBR) and the two-position terminal block on the left

side of the unit towards the rear panel (see Fig. 3.2). Locate the gray wire con-

nected to TB5-2 and to IBR terminal "R". For 208 vac input, disconnect the gray

wire from TB5-2 and then rmly connect it to TB5-1.

4. Locate the output bridge (D1) on the left side towards the front panel (see

g. 3.2). Disconnect and swap leads X2 and X3 from the main transformer. For

208 vac input, X2 is connected to TB3 and X3 is connected to terminal 3 of D1.

Make sure the connections are rmly tightened.

5. Leave all other wires the same.

6. Reinstall cover by sliding it back into the frame rail. Connect the front handle

and connect the Powercut 650 to the 208 vac input power.
