Introduction 1.0 INTRODUCTION The Liebert MPH Series is a managed, single-phase or three-phase power distribution unit that offers monitoring only or monitoring along with receptacle control. Liebert MPH units are available for mounting in either vertical, zero-U configuration and rack-mounting in standard, 19" enclosures. Vertical-mount units may have as many as 27 receptacles. The horizontal-mount units have up to nine receptacles.
Introduction 1.1 General Characteristics • • • • • • • Input current 16 to 32A Single-phase and three-phase power input Input voltages 120VAC, 120/208VAC, 208VAC, 230VAC, 230/400VAC, 240VAC Line-to-Line and Line-to-Neutral Output Receptacles: NEMA and IEC Input connection by hard-wired cords, 10 feet (3m) long Input power cord plugs: L5-20P, L5-30P, L6-20P, L6-30P, L21-30P, IEC-C20, IEC309 3-wire 32A, IEC309 5-wire 32A For details, refer to 6.0 - Specifications. Refer to Table 2 for the dimensions. 1.
Installation in Knurr Miracel™ Rack—Vertical, Zero-U Mount 2.0 INSTALLATION IN KNURR MIRACEL™ RACK—VERTICAL, ZERO-U MOUNT A Liebert MPH can be installed in a Knurr Miracel rack on the frame members using field-supplied Knurr hardware. The unit can be installed on the face or the side of frame members. 2.

Installation in Knurr Miracel™ Rack—Vertical, Zero-U Mount 2.3 Reposition Input Power Cord The Liebert MPH is shipped from the factory with the input power cord entering from the end of the unit. The cord can be repositioned if it will need to enter from the front. To reposition the cord: 1. Remove the four screws retaining the input power plate. 2. Reposition so that power cord enters from front. 3. Reinstall the screws and tighten them.
Installation in Knurr Miracel Rack—Horizontal Rack-Mount 3.0 INSTALLATION IN KNURR MIRACEL RACK—HORIZONTAL RACK-MOUNT A Liebert MPH can be installed in a Knurr Miracel rack in only 1U of equipment space using fieldsupplied Knurr hardware. 3.1 Mounting Hardware and Tools Required Factory-Supplied • L-shaped bracket: 2 • Screws, 6-32 x 1/4": 8 Field-Supplied • Phillips screwdriver 3.2 Install a Liebert MPH in a Knurr Miracel Rack 3.2.
Installing Optional Items 4.0 INSTALLING OPTIONAL ITEMS 4.1 RPC BDM—Basic Display Module The RPC BDM provides local display of electrical status for all connected Liebert MPH systems. Display information is accessed via a navigation switch on the RPC BDM. The RPC BDM is cable-connected to the Liebert RPC allowing the user to locate the display to suit the local reading requirements. A 2-meter cable and general mounting provisions are provided.
Installing Optional Items Figure 9 RPC BDM installation in rack Cable tie fits in small slot on RPC BDM, loops around cabinet member Head of the Liebert MPH Screw in frame fits into hooded slot on back of RPC BDM Figure 10 RPC BDM cable connection port on Liebert RPC RPC BDM cable connection port on Liebert RPC 4.3 Temperature/Humidity Sensor Installation—Optional Optional Liebert SN temperature/humidity sensors are available to assist in monitoring conditions in the rack.
Installing Optional Items To install a sensor on a Knurr Miracel frame member: 1. Assemble the Liebert SN and sensor bracket: a. Insert the sensor bracket base into one end of the sensor support as shown in Figure 11. b. Snap the sensor into the other end of the sensor support. 2. Choose where in the rack to install the sensor assembly. Emerson recommends placing the sensor in the area that is likely to be warmest. 3.
Using the Liebert MPH 5.0 USING THE LIEBERT MPH The Liebert MPH is ready for service after it has been installed in the rack and equipment has been connected to the output sockets. Refer to the Liebert RPC user manual, SL-20825, available at the Liebert Web site, for full details on controlling and monitoring the Liebert MPH: www.liebert.com Emerson recommends following these steps when starting a newly installed Liebert MPH: 1. Shut down and unplug all equipment in the rack from input power sources. 2.
