Uninterruptible power supply (UPS)
The use of an uninterruptible power supply (UPS) guarantees that the PBX can be
operated even in the event of a failure of the 230 V power supply.
Uninterruptible power supply can be provided by the UPS-12V module or an exter-
nal UPS.
4. 3. 3. 1
UPS with UPS-12V module
The charging circuit of the UPS-12V module is designed for lead-acid batteries with
a floating charge voltage of approx. 13.6 V. The charge current can be limited to
1 or 2 A (jumper on the module). The battery switching circuit is protected on the
module with 20 A (Wickmann FK1 20 A). If the polarity is the wrong way around,
the fuse breaks the circuit and must then be replaced.
