1.4 INSTALLATION AND CONNECTIONS

To install VMU-C EM you need to perform the following steps:



Connect the DC 24Vdc power supply (12Vdc to 28Vdc) through an appropriately

sized feeder (recommended feeders: CG, SPM or SPD series)



COM1: communication port for the connection to the RS-485 bus for VMUM-EM

temperature measurement master devices (Pt100 or Pt1000; 2 or 3 wires),
analogue inputs (mV or mA) or for digital input status monitoring (open/closed).

You may connect up to 10 VMU-M EM systems with the relevant VMU-P EM
and/or VMU-O EM modules.
