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 copper bus
bar jumper connected to L2 and L3
needs to be removed and placed in a
safe place for re-use. We suggest the
spare parts box in the power supply.
See previous illustrations.
E. Connections to Single Phase Input Power
WARNING
!
Disconnect input power from the power
supply and input cable before attempt-
ing 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 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 "2.04
cations" for power cable specifications.
CAUTION
!
The primary power source and power
cable must conform to local electrical
code and the recommended circuit pro-
tection and wiring requirements (refer to
table in Section 2).
6. Connect the wires as follows.
•
Set Jumper wire and copper bus bar / jumper
on the contactor. See previous 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.
