Standard 110 VAC Power Supply
The XLi’s internal fault detector can monitor the three output voltages from the primary and the
secondary power supplies. With the Primary Power or Secondary Power indicators in F73 enabled, a
10% decrease in any of the output voltages triggers an alarm. See
“F73 – Alarm Control / Status” on
Warning: Ensure that a disconnect device, such as a switch, with the appropriate voltage/current rating,
is provided when operating/installing the XLi.
Warning: Prior to servicing the interior of a unit with dual power supplies, remove both power cords.
