INPUT VOLTAGE RECONNECT
PROCEDURE
As shipped from the factory, multiple voltage
(208/230/460 VAC) or (200/220/380 - 415/440 VAC)
machines are internally configured for the highest
input voltage (440 or 460 VAC).
1. For Connections to 440 or 460 VAC verify the inter-
nal configurations to the procedures shown below and
refer to Figure A.2.
2. For Connections to 200,208,220,230,380 or 415
VAC follow the procedure shown below and refer to
figure A.2.
NOTE: Turn main power to the machine OFF
before performing the reconnect procedure.
Failure to do so will result in damage to the
machine. DO NOT switch the reconnect bar with
machine power ON.
To Operate at
460 or 440 VAC 1. Open reconnect panel
2. Move input voltage switch
3. Move lead "A" to 440-460
