NOTICE
Use the original screw only. A longer screw might damage the housing of the
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
completely charged batteries, if possible. The charging time of a 2.5 Ah bat‐
tery is approx. five hours.
1.
Switch on the supply voltage for the VAU 01.1U 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 charg‐
ed.
●
Unlit LED "Batt. Charg." indicates that the battery is charged. The
darker the LED flashes, the higher the charging status of the bat‐
tery is.
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!
To check the open-circuit voltage of the battery, insert a voltmeter between
the fusible wire of fuse F1 (see
with USB interface" on page
NOTICE
A short-circuit must not be caused during voltage measuring because a
measurement at the fusible wire of the fuse might deactivate its function!
The open-circuit voltage of the battery must not fall below +21 V, as other‐
wise the battery cells might be damaged.
For this reason, start the charging process of the battery as of an open-circuit
voltage of +22 V by connecting the VAU 01.1U to the +24 V supply. Then the
charging process automatically starts.
For transporting the VAU 01.1U, the plug connection of the battery has to be
removed, see
chapter 8.3 "Replacing Batteries" on page
that there is no connection between the battery and the integrated electron‐
ics.
