INPUT VOLTAGE RECONNECT
PROCEDURE
As shipped from the factory, multiple voltage machines
are internally configured for the highest input voltage
(440-460 VAC), for Codes 11092 and below and (380-
415 VAC), for Codes 11115 and 11116.
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 200,208,220,230,380,400 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.
