2–8 MM300 MOTOR MANAGEMENT SYSTEM – INSTRUCTION MANUAL
ELECTRICAL INSTALLATION CHAPTER 2: INSTALLATION
2.2 Electrical installation
This section describes the electrical installation of the MM300 system. An overview of the
MM300 terminal connections is shown below.
CAUTION
CAUTION:
MM300 is not to be used in any way other than described in this manual.
Figure 9: MM300 terminal connection overview
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.
Table 2: Module slot position
The following figure shows a typical module arrangement for an expanded unit.
CAUTION
CAUTION:
Use gauge size appropriate for the voltage and current draw of the device.
