Installation

Mechanical installation

The Modbus interface module MRP31.0 can be mounted either on the UMC100.3 itself or separately from the UMC100.3 using 
the single mounting kit (SMK3.0).

Mounting the MRP31.0 on the UMC100.3

When the module is installed directly on the UMC100.3 the UMC100.3 with MRP31.0 acts like a device with integrated 
Modbus RTU communication. No additional accessories are needed.

Power

Move down MRP31 until  

snapped-in to fix MRP31 

on UMC100.3

Mounting the MRP31.0 remote from the UMC100.3

When the communication interface is installed remote from the UMC100.3 - e.g. in the cable chamber of a motor control 
center - the MRP31.0 must be separately supplied. This makes it possible to keep the MRP31.0 online even in the case when 
the drawer is removed. Ready made cables are available. But it is also possible to use own cables. For more details see 
section „Using MRP31.0 in a Drawout System“.
