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-mount-
ing in standard, 19" enclosures. Vertical-mount units may have as many as 27 receptacles. The hori-
zontal-mount units have up to nine receptacles. The output receptacles support equipment requiring
connection with NEMA 5-20R, IEC60320-C13 and IEC60320-C19 plugs.
A Liebert MPH with single-phase input has a capacity up to 7.4kW (230VAC; 32A) or 3.6kW
(120VAC; 30A). Three-phase input systems have a capacity up to 22.1kW (230/400VAC; 32A) or
10.7kW (120/208VAC; 30A). For further details, refer to 6.0 - Specifications.
Remote monitoring is enabled by the included communication card, the Liebert RPC
™
, which permits
managing the Liebert MPH over a secure Web page and SNMP-based network management system.
The Liebert RPC permits interconnecting multiple Liebert MPH units and connecting Liebert MPH
with other units for monitoring and management.
A Liebert MPH can be monitored locally with an RPC BDM
™
, an optional display module that con-
nects directly to the communication card. The monitoring unit can be handheld, mounted in or on the
rack or mounted on a nearby wall.
Multiple Liebert MPHs can be centrally managed with Liebert Nform
™
, which adds group-based
receptacle management.
