1. Remove hinged cover.
2. Locate TS2 terminal strip.
3. Remove the two jumper links from TS2.
4. Install the 115/24 VAC transformer (St./No. 9045) onto it's mounting holes using the supplied four 8/32 screws, washers,
lockwashers and nuts.
5. Cut the transformer wires back so as to neatly reach their respective TS2 terminal listed in step 6.
6. Install the supplied spade wire terminals to the transformer wires.
7. Connect the transformer wires to terminal strip TS2 as follows:
White to Terminal 1
Yellow to Terminal 2
Yellow to Terminal 3
Black to Terminal 4
8. Install the hinged cover making sure not to trap and or pinch any wiring.

CONTACT CLOSURE OPERATION
This setting is for welding power sources that require a normally open set of
contacts to operate the contactor. When the normally open set of contacts on K1
relay close it completes the circuit and energizes the contactor. Pins
F and E on RC1
will give contact closure operation by the wire feeder when the TS1 jumper is from
terminal
1 to 2.
VOLTAGE FEEDBACK CONTACTOR OPERATION
This setting is for power sources that require voltage feedback to operate the
contactor. When K1 relay closes voltage will be sent back to the welding power
source to energize the contactor. This setting is normally used with the 115/24 VAC
transformer option (St./No. 9045) to send 115 VAC back to the welding power
source to operate the contactor circuit. Pins
F and B on RC1 will give voltage
feedback operation by the wire feeder when the TS1 jumper is from terminal 2 to 3.
