4.1.1 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
external UPS.
4.1.1.1 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 lim-
ited 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.
If a battery isolating point is provided, it must be equipped to handle a current of
20 A (at 12 VDC).
