Alpha Technologies XM2-300CE-HP - Manual (Page 53)

Before turning on the AC voltage input breaker, use a voltmeter to verify the input voltage 1.
is within specifications.
When the proper voltage is present, verify the battery voltage indicated on the Smart 2.
Display is greater than 10.5Vdc. 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 this short period of time, but exercise
caution during this changeover as the grounding circuit to the power supply is broken.
If the battery is at or below the low voltage cutoff, then the power supply will NOT trans-
fer to battery back up and there will be a momentary power outage to the cable system
while you make this changeover.
Turn on the AC input power.
