needed. If this occurs repeatedly, contact an authorized service provider.

7. Check the UPS LEDs to be sure a battery or site wiring problem has not

occurred. Refer to the UPS documentation.

8. If the UPS sleep mode initiated, disable sleep mode for proper operation. The

UPS sleep mode can be turned off through the configuration mode on the

particularly if a recent air conditioning outage has occurred.

NOTE: The optimal operating temperature for UPS batteries is 25°C

increase in ambient temperature above the optimal temperature, battery
life is reduced by 50 percent.

instructions.
