1. Use a voltmeter to verify the input voltage is within specifications before turning on the
AC voltage input breaker.
2. Once the proper voltage is present, verify the battery voltage indicated on the Smart
Display is greater than 31.5V. Disconnect the power supply from the generator output
and plug the power supply input cord into the convenience outlet within the enclosure.
The power supply operates on battery backup for a short period of time. Exercise caution
during this changeover. The grounding circuit to the power supply is broken while in the
act of unplugging and reconnecting the power supply.
If the batteries are at or below the low voltage cutoff, the power supply will not transfer to
battery back-up and there will be a momentary power outage to the cable system while
you make this changeover.
3. Turn on the AC input power.
. Shut down the generator and remove the grounding system.
5.0 Operation, continued
5.6 Resumption of Utility Power
Care must be exercised to ensure that both powering systems are not connected at the same time,
or damage to the power supply and/or the generator may result.
Use caution when disconnecting a generator and reconnecting to utility power. Dangerous
voltages are present.
WARNING!
CAUTION!
