phase.
E. 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. See "A.
Cover Removal".
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 sup-
ply.
4. If the power cable being used is not the
factory - supplied cable, use a three - con-
ductor 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 specications.
CAUTION
The primary power source and power cable
must conform to local electrical code and the
recommended circuit protection and wiring
requirements (refer to table in Section 2).
6. Connect the wires as follows.
• Connect Bus Bar Jumpers on the con-
tactor as shown in prior illustration and
on label in the power supply.
• Green / Yellow wire to Ground.
7. With a little slack in the wires, tighten
the through - hole protector to secure the
power cable.
8. Reinstall the Power Supply cover. See "B.
Cover Installation".
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.
F. 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. See "A.
Cover Removal".
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

ply.
4. Using a customer supplied four - conductor
input power cable for the voltage desired,
strip back the insulation on the individual
wires.
