CP400 Installation Instructions
P/D 022597
INSTALLATION
CAUTION! Make all connections with the POWER OFF to avoid injury to the installer or damage
to the device.
NOTE! The CP400 is designed to transfer command signals generated on one phase of a three
phase system to one or more of the remaining phases. It will isolate phases from each other to
prevent trickle-through of line current from an energized phase to an inert phase.
1. Strip 3/4" of insulation from the ends of the conductors and make connections as shown in the
Wiring Diagram.
2. Check connections to be sure they are tight and no bare conductors are exposed.
3. Make sure the load or installation does not exceed the device rating.
4. Install into a standard single or multi-gang electrical wall box. Use a deep box to avoid
interference with box fittings and allow room for wiring connections.
Mount the device in the wallbox and install the cover plate.
CHECKOUT
1. Restore the power.
2. Transmit command signals from controller on one phase of coupled system and test for proper
response from receivers on other phase(s) of coupled system (and vice versa).
3. Test for Signal Strength and Noise once again across coupled system using the AR300 and
AT300.
