4.1 Support
The Support provides the Radio Core with integrated mechanical attachment,
power conversion and cooling. It consists of a mounting bracket, a fan unit,
and a PSU.
4.1.1 Mounting Bracket
The mounting bracket provides integrated mechanical attachment for wall and
pole mounting, and attachment points for the rail bracket.
4.1.2 Fan Unit
The fan unit operates autonomous against ambient temperature to cool the
Radio Core.
The fan unit can be removed when all the following cases applies:
•
The radio is installed on a single support.
•
The radio is installed in an indoor environment.
•
Maximum configured power is 2x3 W.
•
The ambient temperature is maximum 30° C.
•
The radio is installed vertically.
Note:
Radios with removed fan units must not be installed above each
other. It is important that the fan unit is removed physically to ensure
cooling.
4.1.3 PSU
The PSU provides power to the Radio Core and the fan unit.
The PSU is available in two variants to support AC input and DC −48 V input.
The DC variant handles both 2-wire and 3-wire connections.
Included in the PSU is also the external alarm interface and communication
between PSU and Radio Core.
