MAINTENANCE
The PowerSure ProActive UPS requires very little maintenance. The batteries
are valve regulated, nonspillable, lead acid, and require that they be kept
charged to obtain their designed life. When ON, the UPS continuously charges
the batteries when connected to the utility supply.
When storing the UPS for any length of time, it is recommended to plug in and
turn on the UPS for at least 24 hours every four to six months to ensure full
recharge of the batteries.
The following will help ensure trouble-free operation for years to come:
- Vacuum dust from the ventilation intake occasionally.
- Wipe the cover periodically with a dry cloth.
-
Occasionally press the UPS test button to test the condition of the batteries.
