This section of the OEM documentation is for Test and Compliance Engineers
and Service Technicians. It covers correct setup and installation, theory of
operations, technical specifications,
MPMView software and
troubleshooting/diagnostics.
Before You Start:
The MPM unit is designed to be installed in a pre-assembled cart with all power
and communications cables properly connected and tested prior to delivery to
the end use application.
When servicing or testing MPM on a technician bench, make sure that all power
and battery communications cables are connected as described in the
Setup
and Operation section (p.18) before powering the unit.
NOTE: For units connected to LiFePO
4
type batteries with “smart battery”
communications interface
1
, the communications cable between the MPM unit
and smart battery communication connection must be connected before
energizing the MPM unit to prevent possible damage to the protection and
management circuits within the battery.
MPM is UL listed under the UL1778 standards specification for Uninterruptible
Power Supplies (UPS). However, the operational behavior of the MPM is
different than a UPS. Refer to the section System Overview & Theory of
Operations for a description of the how the MPM is designed to operate in
various conditions.
