CUTMASTER A40
Manual 0-4978 3-3 INSTALLATION
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 sup-
ply 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.

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.
• Set Jumper wire and copper bus bar /
jumper on the contactor. See previous
illustrations.
