6.3
Maintenance
The UPStation GXT UPS requires very little maintenance. The batteries are valve regulated, non-spillable, lead acid,
and should be kept charged to obtain their designed life. The UPS continuously charges the batteries when connected to
the mains supply.
When storing the UPS for any length of time, it is recommended to apply power to the UPS for at least 24 hours every
four to six months to ensure full recharge of the batteries. In no case should the unit be stored in excess of nine months
without recharge. Periodically, examine the vents on the front and rear of the cabinet, and remove any obstructions from
the surface of the vents.
