Wiring Power to the Unit
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:
• 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.
