Connecting Cmr-1; Connecting An Earth Ground - Irritrol Total Control Mode D'emploi

CONNECTING CMR-1

As shown in the illustration below, the CMR-1 receiver plug assembly simply plugs into the
receptacle provided in the back of the Total Control control module. The CMR-1 receiver
plug assembly also requires connection to the 24 VAC power terminals.

CONNECTING AN EARTH GROUND

The surge protection components provided in the Total Control reduce the potential for
surge damage by shunting induced high voltage spikes to earth ground. Therefore, an
important step in the installation process is to properly connect the controller to an earth
ground source, especially if the controller is located in a lightning-prone area.
Caution:
The built-in surge protection components cannot effectively protect the
controller circuitry from power surge unless properly connected to an earth ground source.
The 5-year lightning warranty will be void if proper earth grounding measures are not
completed as specifi ed in the following procedure.
To connect an earth ground:
1. Route a 6 AWG (10 mm2) solid copper wire (avoiding wire bends less than 8" [2.4 m]
radius) from the earth ground device (copper-clad rod or plate) to one of the controller
ground lugs provided. Refer to
