3-4 Trane Liqui-Flo Addendum
3.3 Cabinet Wire Routing
All wiring should be installed in conformance with the applicable local, national, and
international codes (for example, NEC/CEC). Figures 3.3 and 3.4 show the wire
routing, grounding terminal, and power terminal strips of the cabinet. Control wiring
enters the cabinet through the three holes on the left side and terminates at the
control panel’s terminal block. Tighten the control wire connections from 7.1 to 8.9
in-lb.
3.4 Grounding the Cabinet
Use the following steps to ground the cabinet:
Step 1. Open the cabinet’s door. The grounding stud is located on the left side of the
cabinet.
Step 2. Run a suitable grounding conductor unbroken from the cabinet’s ground stud
to the motor’s ground terminal and then to earth ground. See figures 3.3 and
3.4. The cabinet’s ground stud connection point has two 5/16" socket-head
screws. Tighten the ground connections to 23 ft lbs (+ 10%).
Step 3. Connect a suitable grounding conductor to the motor frame and the
delta-wye transformer (if used). Run each conductor unbroken to earth
ground.
