MAINTENANCE
The UPStation® GX UPS normally requires very little maintenance.
Keep the sealed, maintenance-free batteries fully charged to obtain designed life of 5
years. During normal operation, the UPS continuously charges the batteries.
To store or deactivate the UPS for any length of time, charge it no less frequently than once
every 6 months. Switch UPS OFF when not connected to the utility AC. To charge the
batteries, connect the UPS to the utility and turn it ON for a minimum of 4 hours.
Replace batteries after 5 years or sooner if exposed to adverse conditions. Refer battery
replacement to qualified service personnel only. Heed cautions at the front of this manual
at all times. Call Liebert Technical Support at 1-800-222-5877 for battery replacement
instructions.

WARNING: Battery maintenance procedures expose hazardous live parts. Refer
servicing to qualified personnel only.
