DECT 4070 IO/EO BASE STATIONS TERMINALS
Ed. 042/2 Réf. 3EH 21000 BSAA
Local power supply
It is possible to connect a local power supply (230V/42V – 150 mA adapter) to an accessible socket
on the lower part of the 4070 IO/EO base.
The local power supply is used in the following cases:
- main power supply not authorized on the line's wires (depending on specific installation require-
ments)
- to increase the cable length between the interface and the station
- reduction in the system's electrical consumption.
When the external power supply is connected, the base passes automatically to local power supply mo-
de. In the event of a power cut, the base is not supplied.
