●
Close the cover
●
Attach the cover with the original M5x10 Z4 screw to the housing by
tightening it with a torque of 24.8 lbf in (2.8 Nm)
11. Refit fuse F1.
Possible data loss due to an uncharged battery.
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.
Battery damage due to deep discharge.
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
chapter 12.5 "Fuse F1" on page 35
) and the 0 V con-
nection of X1S1.
UPS damage due to short-circuit.
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!
