This section describes the electrical installation of the MM300 system. An overview of the
MM300 terminal connections is shown below.
MM300 is not to be used in any way other than described in this manual.

Three-phase and
RS485 communications
residual ground CT
and thermistor input
inputs
I/O card includes:
Core-balance ground CT input
two contactor outputs (form-A)
•
six programmable inputs
•
• single-phase VT input (60 to 300 V AC)
The MM300 can contain up to eight modules. The first four modules (slots A through D)
comprise the base unit, and the next four modules (slots E through H) comprise the
optional expanded unit.

The following figure shows a typical module arrangement for an expanded unit.
Use gauge size appropriate for the voltage and current draw of the device.
