2.1

Attaching Input Power Cords—Hard-Wired Models Only

MPH2’s with integral power cords need no assembly before installation. Units with hard-wired input 

power require attachment of input power cords. See 

Table 1

 for wire sizing.

Hard-wired models may be wired with or without conduit.

2.1.1 Attaching Input Power Cords Without Conduit

1. Remove the end cap. It is held in place with two T10 Torx screws.
2. Slide the terminal block cover off.
3. Loosen the strain-relief collar. It is held in place with two Phillips head PH1 screws.
4. Strip the insulation from the individual wires as required to fit into the terminal block.

Recommended stripping length for MPH2 units rated less than 32A is 9mm; for MPH2’s rated or 

higher, 11mm.

5. Slip the power cord through the hole in the end cap and through the strain-relief collar.
6. Loosen the terminal block screws.
7. Insert the wires into the terminal block according to the labeling inside the MPH2; tighten each 

terminal block screw after inserting a wire. Refer to 

Table 2

 for tightening torque.

8. Tighten the strain-relief collar around the input power cord. The cord’s outer insulation covering 

should extend through the bracket.

9. Replace the terminal block cover by either sliding it on or snapping it into place.
10. Reattach the end cap to the MPH2 with the two screws removed in 

Step 1
