Figure 4.7: IPM Relay Electrical Connections: Digital Inputs
The IPM has a number of digital inputs to allow external devices to interact with the relay. Each of
these inputs is activated when it is shorted to the DI+ terminal (1) by a normally open contact or
pushbutton.
The MCI input is a special input that is used to monitor the state of the outlet‟s main contactor for the
IPM‟s frozen contactor protection. Wire a normally open auxiliary contact from the main contactor to
this input to allow this function to operate correctly.
For a detailed explanation of the functions of each of these inputs, refer to Section 12.6.1.
The Digital Input (DI) Screen terminal is used to terminate the screens of the cables that are used for
the digital inputs.
NOTE
If the IPM is to be installed in areas of high electrical interference, it is
recommended that the wiring for the digital inputs be run in screened
cables.
