Overview
The usage of a fan unit is recommended, if sufficient air flow for cooling the 1643 AM
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. The fan unit has no air filter and can only be used
together with a DC powered unit.
The following two fan unit types can be used together with a 1643 AM unit:
• CC848841888
• CC848949657.
