The programmed “Measurement Type” will determine the signals monitored and the associated wiring connection
requirements. Wire the appropriate measurement signals from the coupon or bond to the terminal block on the RMU1.
The green terminal block is pluggable; it may be easier to remove it from the RMU1 while wiring. Strip ¼”(6mm) of
insulation off the end of each measurement wire before inserting the wire into the terminal block. Use a small Philips-
style or flat blade screwdriver to tighten the connector clamps to the measurement wiring.
Unused analog input channels should be disabled using the programming interface.
An optional wiring kit (A20103RMU10), containing factory installed crimp terminals, wiring and cable ties, is optionally
available. Electrical connections to the RMU1 can be made using direct wire connections (22 to 14 AWG wire size.
Lightning immunity is enhanced by utilizing 600 volt, 105C rated wiring (as supplied with the optional wiring kit) which
has a thicker insulation system and higher voltage breakdown rating as compared to more common 300 volt rated wiring
systems.
