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:
•Other equipment cannot introduce spikes, noise, surges or dips into the power circuit.
•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.
