RMU5-MAN-001
Note: When installing transformers with multiple primary taps, ensure that un-used tap wires are properly
capped!
Next, extend the transformer 24VAC secondary wires with additional wire (as needed) to reach the RMU5 power input.
Remove the orange pluggable terminal block from the RMU5, and connect the transformer secondary wires to the
terminal block. Before plugging the terminal block back into the RMU5, enable primary power to the transformer, and
by using a multimeter, verify that the transformer output is within the range of 20 to 28VAC.
If the transformer output voltage is below or above that range, re-verification of the transformer primary tap
selection will be necessary.
Shut off primary power to the transformer before continuing. Plug the orange terminal block back into the receptacle
on the RMU5. The connection to the RMU5 should be as shown in Figure 6.

The RMU5 GPS kit (P/N A20A03GPS01) is shown in Figure 7. This kit is ordered as a factory installed item. The GPS
board shown is installed inside the RMU5 at time of manufacturing. Included in the kit is a pre-terminated 10 meter
(33’) RF cable and a GPS antenna.
