4. Make sure the battery is fully charged periodically every 3 months if the temperature is approximately 24 and every month if the temperature is higher than 37 by operating the UPS for at least six hours e Store the batteries in a cool place may be stored separately from the UPS Never store a discharged battery 11 Production amp Trading Co AG PTC 0120BA1UM REV A Charge discharge Cycles The number of times and the depth of battery discharges during AC input failure affects the service life of the battery If the battery is allowed to discharge only to 50 of its charge the number of charge discharge cycles before it fails will be three times the number of cycles had it been allowed to reach 30 charge Battery life may be prolonged by limiting the operating time on battery power to the minimum required by the system to perform an orderly shutdown 7 2 Replacing the Battery Pack For ease of use the battery of the PTC 0120BA 1A is packaged within a Removable Battery Pack P N M350380 that may be ordered separately During storage the Battery Pack may be removed and stored separately in a cooled ambient To remove the Battery Pack from the UPS a b c d e f To install a a b c d e Turn OFF the Input and Output ON OFF switches Disconnect J1 and J2 from the rear panel Open the Battery Connector access cover Remove screws Disconnect the connec
