Introduction 1.3 Appearance and Components 1.3.1 Controls and Indicators—RPC2™ The MPH2 rack PDU is monitored and managed by the factory-installed RPC2 communications module. This manual presents information about the MPH2’s functions and features. For details on operating the MPH2 through the RPC2 communications module, refer to the RPC2 user manual, SL-20841. The document is available at Emerson’s Web site: http://www.emersonnetworkpower.com The RPC2 is installed near the middle of the MPH2 rack PDU.
Introduction Figure 3 MPH2 LCD and LED’s Onboard LCD MPH2™Managed Rack Power Distribution 2.96A RX MPH2 121.1V 1.3.4 L2 L3 2kWh 359W i 1 Left Arrow Key L1 Line Input Status LED’s Select Key TX Right Arrow Key Power Components The component location and type depend on the model of the MPH2 rack PDU. For example, units with a “B” as the fourth character in the model name do not have LED’s at their outlets; see Figures 4, 5, 6 and 7.
Introduction Branch Overcurrent Protection Models having more than 16A input current rating are equipped with branch overcurrent protection. This protects each outlet group against overload and short circuit. The branch circuit breaker is a UL 489-listed breaker with a flush-mount, rocker-style actuator. The circuit breaker interrupts the fault current flowing in the line-to-line, line-to-neutral and line-to-PE conductors of the branch circuits.
Installation 2.0 INSTALLATION An MPH2 rack PDU can be installed in an Emerson rack on the frame members using field-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. NOTE Follow all local and national electrical codes, standards and recommended practices.
Installation 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. 2. 3. 4. 5. 6. 7. 8. 9. 10. Figure 7 Remove the end cap. It is held in place with two T10 Torx screws. Slide the terminal block cover off.
Installation 2.1.2 Attaching Input Power Cords With Conduit 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. Figure 8 Remove the end cap. It is held in place with two T10 Torx screws. Slide the terminal block cover off. Remove the cable clamp assembly. It is held in place with four nuts (see Figure 7). 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.

Installation 2.3 Installing an MPH2 in an Emerson® Rack 2.3.1 Mounting Hardware and Tools Required Factory-Supplied • Two brackets • Mounting buttons Field-Supplied • Spring nuts (supplied with Emerson rack) • Phillips #2 screwdriver Determine where in the Emerson rack the PDU will be installed and follow the instructions below. Installation requires attaching two brackets to the PDU, inserting four spring nuts into the rack and using the brackets to attach the PDU to the rack.
Installation 2.3.2 Safety Earth Ground Connection Ensure that the safety earth connection is made before any equipment is connected to Emerson’s MPH2 rack PDU. Units with factory-attached input power cords have an internal grounding conductor. The ground wire establishes the same ground reference between the MPH2 rack PDU and the rack. The ground-wire and hardware are available as an option from Emerson.
Installation 2.3.3 Recommended Electrical Backup Protection A field-provided external circuit breaker must be installed upstream of the MPH2 rack PDU. The circuit breaker must be sized according to the input rating of the PDU. The circuit breaker rating must meet the values in Table 3. The external circuit breaker serves as the primary input power disconnect for the MPH2.
Installation 2.4 Connecting Rack Equipment NOTE Circuit breakers on Emerson’s MPH2 rack PDU are opened at the factory. The open circuit breakers help protect against damage to the connected load from high inrush current when input power is connected. The circuit breakers must be closed before the unit will supply power to the connected load. Do not close the breakers until after all rack equipment is connected to the MPH2 rack PDU.
Installation 2.5 Installing Optional Items The following items may be added to an MPH2 rack PDU system but are not required. • RPC Basic Display Module • Liebert® SN temperature/humidity sensors 2.5.1 RPC Basic Display Module The RPC Basic Display Module (BDM) provides local display of parametric data, including electrical status, temperature and humidity for all connected MPH2 rack PDU’s. Display information is accessed via a navigation switch on the BDM.
Installation To install an RPC BDM in a rack: 1. Determine the mounting location. 2. Insert a spring nut into a T-slot on the frame member where the RPC BDM will be installed. Figure 14 Inserting the spring nut into a T-slot Insert a spring nut into a T-slot... ... then flip it so that it is square in the slot 3. Insert the MPH2 rack PDU screw into the spacer sleeve. 4. Insert the MPH2 rack PDU screw into the spring nut and tighten securely with a flat-head screwdriver. 5.
