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 unit’s operation will not be affected if any other equipment
develops a short circuit across the power line.
Dimensions: 9.72" x 6.22" (W x H)
