3.0 INTRODUCTION TO MULTIPLE METER
UNITS (MMU)
3.1 Application
This Install Manual describes a line of Multiple Meter Units (MMU) used in
monitoring electrical usage in commercial, industrial, or institutional facilities.
Voltage and current are continuously measured and updated to provide highly
accurate, true RMS power information via current sensors.
3.2 General Description
The MMU allows for compact installation of multiple meters that allows for easy
and centralized reading. A single MMU cabinet can be configured to contain up
to 8, 16, or 24 meters of different voltage configurations (i.e. 208V and 480V).
