11. Refit fuse F1.
NOTICE
If the new battery is not yet charged, there is no sufficient UPS protection for a
controlled shutdown of the PC during the charging period. Therefore use com-
pletely charged batteries, if possible. The charging time of a 2.5 Ah battery is ap-
prox. five hours.
Testing the new battery
1. Switch on the supply voltage for the UPS again.
2. Observe the "Batt. Charg." display on the front panel:
LED "Batt. Charg." lights green: Battery is charged
●
LED "Batt. Charg." flashes: The battery is nearly completely charged
●
Unlit LED "Batt. Charg." indicates that the battery is charged. The darker
●
the LED flashes, the higher the charging status of the battery
14.4 VAU 01.1U and VAU 01.1S – Storage
Recommended value for the storage time
The storage time is two years at an average ambient temperature of +25 °C.
NOTICE
If the storage temperature is unclear or if the storage time has exceeded two
years, check the open-circuit voltage of the battery regularly – as described in
the following section!
Checking the open-circuit voltage
To check the open-circuit voltage of the battery, insert a voltmeter between the
fusible wire of fuse F1 (see
nection of X1S1.
NOTICE
A short-circuit must not be caused during voltage measuring because a measure-
ment at the fusible wire of the fuse might deactivate its function!
