Maintenance

PowerValue 11 RT 6-10 kVA UPS only requires minimal
maintenance.
Charge the UPS regularly to maximize the expected life
of the battery. When connected to the mains power, the
UPS charges the batteries and prevents the batteries from
overcharging and over-discharging.
• Replace the batteries when the battery service life has
been exceeded (3~5 years at 25°C ambient temperature).
Contact local ABB or an agent authorized by ABB.
• Charge the UPS once every 4 to 6 months if it has not
been used for a long time.
• In high temperature regions, charge and discharge the
battery every 2 months. The standard charging time should
be of at least 12 hours.
• Replace the battery when the discharge time is less than
50% of specified after full charge. Check the battery
connection or contact your local dealer to order a new
battery.
