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).
