WIRING POWER TO THE UNIT
The 110 Vac outlet must be dedicated to the unit only. This
outlet should be wired back to its own 10 Amp minimum
circuit breaker. This will prevent two problems:
1. Other equipment cannot introduce spikes, noise, surges,
or dips into the power circuit.
2. The system’s operation will not be affected if any other
equipment develops a short circuit across the power
line.
Connect the transformer into a 110 Vac outlet after all
connections have been made, any other type of outlet will
cause damage to the system.
