Wiring Power to the EL25

Wiring Power to the EL25
The 110 VAC outlet must be dedicated to the EL25 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.
