The UAI16-1 board can optionally be powered by an external EPS48 power supply depending on the
requirements for remotely powering the terminals.
The mains socket for the external EPS48 power supply must be installed as near as possible to the
system and be easily accessible.

0.85A. Its use is limited to UAI16-1 boards.
The power supply lead is used as the master switch. The power supply socket must be
located or installed close to the hardware and allow easy access.
The power supply cord is used as the main disconnect device, ensure that the socket-
outlet is installed near the equipment and is easily accessible.

OXO Connect is supplied with one or more integrated batteries; they are mounted and fixed with a
solid bar on the rear plate.
Caution:

The batteries are disconnected during transport using a switch soldered onto the power supply board.
When the mains cable is inserted in the socket, the switch is closed by a lever incorporated in the
