Overview
External fan module
External fan module
The external fan module combined with the reinforcement plates
is employed to provide perfect cooling of a SINAMICS S120
Combi Power Module.
To cool the SINAMICS S120 Combi Power Modules, a volumetric
flow of air through the heatsink of at least 160 m
3
/h is required.
The external fan module delivers a maximum volumetric flow rate
of 290 m
3
/h. This dimensioning ensures an adequate air flow
rate, even with a lower supply voltage or with a slightly soiled
heatsink.
Due to the encapsulated electronics and the ball-bearing-
mounted closed rotor, the fan module can be used even under
exacting environmental conditions. The fans are equipped with
electronic reverse-polarity, blocking and overload protection
systems. To ensure maximum machine availability, the fan speed
is monitored. A user alarm is displayed
if the fan stops.

Overview
Reinforcement plates
Reinforcement plates
It is essential to ensure that the air actually flows through the
heatsink. The gap between the fan module and heatsink must
therefore be closed. The reinforcement plates must be used for
this purpose where possible.
The reinforcement plates
•
Close the gap between the fan module and
heatsink
•
Reinforce the rear wall of the control cabinet for
sealed installation
•
Guarantee ideal ventilation spaces
