NOTE!
There is only one jumper setting that
changes between the single and three
phase settings. To change from single
phase to three phase, the jumper con-
nected to L2 needs to be removed and
placed on the other L3 connection so
both ends of the jumper are attached to
the same electrical point. See previous
illustrations..
A. Connections to Single Phase Input Power
WARNING
Disconnect input power from the power
supply and input cable before attempting
this procedure.
These instructions are for changing the input power and
or cable on the 208/230, 400, 460 VAC Power Supply to
Single - Phase input power.
1. Remove the Power Supply cover per instructions
found in Section 5.
2. Disconnect the original input power cable from
the main input contactor and the chassis ground
connection.
3. Loosen the through - hole protector on the back
panel of the power supply. Pull the original
power cable out of power supply.
4. If the power cable being used is not the factory
- supplied cable, use a three - conductor input
power cable for the voltage desired and strip
back the insulation on the individual wires.
5. Pass the cable being used through the access
opening in the back panel of the power supply.
Refer to Section 2 for power cable specifications.
CAUTION
The primary power source
and power cable must con-
form to local electrical code
and the recommended circuit
protection and wiring re-
quirements (refer to table in
Section 2).
6. Connect the wires as follows.
• Set Jumper wires on the contactor. See previ-
ous illustrations.
• Green / Yellow wire to Ground.
• Remaining wires to L1 and L2 input. It does
not matter what order these wires are at-
tached.
7. With a little slack in the wires, tighten the through
- hole protector to secure the power cable.
8. Reinstall the Power Supply cover per instructions
found in Section 5.
9. Connect the opposite end of individual wires to
a customer supplied plug or main disconnect.
10. Connect the input power cable (or close the main
disconnect switch) to supply power.
B. Connections to Three Phase Input Power
WARNING
Disconnect input power from the power
supply and input cable before attempting
this procedure.
These instructions are for changing the input power and
or cable on the 208/230, 400, 460 VAC Power Supply to
Three - Phase input power.
1. Remove the Power Supply cover per instructions
found in Section 5.
2. Disconnect the original input power cable from
the main input contactor and the chassis ground
connection.
3. Loosen the through - hole protector on the back
panel of the power supply. Pull the original
power cable out of the power supply.
4. Using a customer supplied four - conductor input
power cable for the voltage desired, strip back
the insulation on the individual wires.
5. Pass the cable being used through the access
opening in the back panel of the power supply.
Refer to Section 2 for power cable specifications.
CAUTION
The primary power source
and power cable must con-
form to local electrical code
and the recommended circuit
protection and wiring re-
quirements (refer to table in
