2.0 Installation
An MPH2 Rack PDU can be installed in an Emerson rack on the frame members using factory-supplied
hardware. The unit can be installed on the face or the side of frame members. The unit can be mounted so
that the power cord exits either the top or bottom of the rack.
Disconnect Required for Hard-Wired MPH2 Units
A readily-accessible input-power disconnect device must be installed near the MPH2 Rack PDU.
Input Power Location for MPH2 Units with Factory-Installed Power Cords
The input-power socket or outlet must be installed near the MPH2 and must be easily accessible.
2.1 Attaching Input Power Cords—Hard-wired Models Only
MPH2s with integral power cords need no assembly before installation. Units with hard-wired input power
require attachment of input-power cords. See Table 2-1 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 32 A is 9 mm; for MPH2s rated 40 A or
higher, 11 mm.
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 2-2 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.
NOTE
Follow all local and national electrical codes, standards and recommended practices.
