Technical data for fan unit

Overview
The usage of a fan unit (CC848949657) is recommended, if sufficient air flow for
cooling the 1643 AMS unit cannot be guaranteed. A fan unit is required, if the unit
will be mounted in an outdoor street cabinet, because the fan unit provides sufficient
air flow to cool the unit in a thermally hostile environment such as street cabinets.
Proper cooling is ensured as long as one fan is still working. A fan unit can be
replaced from the front of the street cabinet without removing or disrupting the
operation of the 1643 AMS. The fan unit has no air filter.
