DANGER!
PowerValue 11 RT G2 1-3 kVA UPS requires only
minimal maintenance.
Charge the UPS regularly to maximize the
expected life of the battery. When connected to
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 (around three to five
years at 25 °C ambient temperature). Contact
your local ABB or an agent authorized by
ABB for replacements.
• Charge the UPS once every four to six months
if it is not used regularly.
• In high-temperature regions, charge and
discharge the battery every two months.
The standard charging time should be
at least 12 hours.
• Replace the battery when the discharge time
is less than 50 percent of specified after fully
charging. Check the battery connection or
contact your local dealer to order a new
battery.
