B. Connect power and earth wiring and select voltage
operating range
3. Select the voltage operating range
Connect the supplied wire jumpers to the appropriate terminals
to select input voltage.The RMM2-E is supplied jumpered for 230
volts.
4. Connect wiring from power source to
designated terminals on RMM2-E.
Use only copper conductors. Connect power cable wires to the
terminals marked L1 and L2 on the RMM2-E. If power is being
daisy chained, be sure to maintain polarity of L1 and L2 wiring
for incoming and outgoing wires. The terminals accept stranded
wires from 0.2 – 2,5 mm . (0,2 - 4 mm

5. Connect earth wiring.
Connect the earth wire(s) to the earth terminals mounted on the
DIN rail. The terminals accept 0,8 - 2,5 mm
wires.
C. Connect RTD Cables to the RMM2-E
The RMM2-E has terminals for 8 three-wire, RTDs (Pt 100
temperature sensors, to IEC 751); do not use other types of RTDs.
Select RTDs appropriate for the usage:
MONI-PT100-NH Temperature sensor for
non-hazardous areas
MONI-PT100-EXE Temperature sensor for hazardous areas
Install each RTD in accordance with the installation instructions
shipped with it, and run the RTD lead wires to the RMM2-E.
Note: Resistance of lead wires from each RTD must not exceed
20 Ω (e.g. 150 m with 3 x 1,5 mm
solid wire)
