Uninterruptible Power Supply (UPS)

The use of an uninterruptible power supply (UPS) guarantees that the PBX can be
reliably operated even in the event of a failure of the 230 VAC 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. The charge current can be limited
to 1 or 2 A. The battery switching circuit is secured 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.
