Electrical installation
This section describes the electrical installation of the MX350 system. An overview of the
MX350 terminal connections is shown below.
Figure 8: MX350 terminal connection overview
The MX350 can contain up to ten modules. The first four modules (slots A through D) reside
in the base unit while all subsequent modules (slots E and J) reside in expansion units.
Each expansion unit can contain up to two modules. Slots A through G make up the basic
MX350. The next three modules (slots H through J) are optional I/O modules.
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.
The MX350 is not to be used in any way other than described in this manual.
