Attach the rear panel

Attach the power cord ground wire to the heatsink.

Tighten to 2.3 N∙m (20 lbf·in).

Run the remaining power cord wires through the center panel slot.

Attach the power cord leads to the appropriate terminal.

Tighten to 2.3 N∙m (20 lbf·in).

1	Power cord ground wire to heatsink
2	Power cord pass-through
3	CSA 1-phase
4	CE/CCC 1-phase
5	CSA 3-phase
6	CE/CCC 3-phase

Connect 2 wires for the 1-phase models:
- CSA models: wires are black (BLK) and white (WHT).
- CE/CCC models: wires are brown (BRN) and blue (BLU).
Connect 3 wires for the 3-phase models:
- CSA models: wires are white (WHT), red (RED), and black (BLK).
- CE/CCC models: wires are blue (BLU), brown (BRN), and gray (GRY).

Connect the machine interface port using 2 screws if installed.

Tighten to 1.1 N∙m (10 lbf·in).

1	Gas supply hose
2	Ground clip
3	Ground wire
4	Machine interface port screws

Plug the serial interface cable into the RS-485 Printed Circuit Board (PCB) if installed.

Connect the ground wire to the air filter assembly.

Tighten to 2.3 N∙m (20 lbf·in).

Snap the rear panel assembly back into place.

Make sure no wires are pinched as you put the panel back in place.

Push-to-connect the looped gas supply hose to the air filter assembly.

Insert the hose far enough so the marked line reaches the connector. The bottom of the loop should rest on the plastic shelf to the left of the fan.

Make sure the looped gas supply hose is not kinked.

Note:

If the gas supply hose is kinked, discard it and replace it with a new hose. The integrity of the hose is compromised once the hose is kinked.

Place the ground clip back onto the plastic tab on the rear panel.

Complete the following procedures:
