5-4-10 UPS Battery Description (cont’d)
The UPS batteries will drain slightly when the system is in the off condition. The off condition is defined
as:
• Circuit Breaker in the OFF position
• System unplugged from the wall outlet
If the system is left in the OFF condition for an extended period of time (3 to 5 days or more), the system
may not boot up or may beep when turned ON. Should this occur, the system needs to recharge the
UPS batteries. This could take 15 minutes to as long as 10 hours uninterrupted, depending on the
battery age, system input voltage and system temperature. To eliminate draining the UPS batteries, the
system should remain plugged into the wall outlet with the circuit breaker in the ON position.
