ELECTRIC SHOCK can kill.
• Only qualified personnel should per-
form this installation.
• Turn the input power OFF at the dis-
connect switch or fuse box before working on this
equipment.

Auxiliary power for wire feeder operation is available at
both a 14-pin MS receptacle and at terminal strips
with screw-type connections located on the front of
the machine. Refer to the Installation section for
pinouts and lead designations. The two circuits are
isolated, and each is protected by a circuit breaker.
The following descriptions show how to connect the
wire feeders using either the 14-pin MS receptacle or
the terminal strip.
