9.11 Setting the Battery Test
A software-controlled battery test facility can be initiated from the Operator Control Panel on an 'immediate' or
'periodic' basis. This test turns off the rectifier and runs the inverter (and load) from the battery for a predetermined
period. If the battery voltage falls below a preset minimum level prior to the termination of the test period a
'BATTERY: TEST FAILED' alarm is annunciated and the rectifier is immediately turned on to prevent the load
transferring to bypass and recharge the battery. This instructions given below initiates an immediate battery test.
For the following test to be 'meaningful' as part of the UPS commissioning procedure, the batteries should be fully
charged prior to the test being carried out. The UPS rectifier section must therefore be allowed to operate with the
battery connected for several hours to provide the battery with an adequate initial charge.
Caution
Do not continue with this procedure if the battery has not yet been charged
