Information on control cabinet cooling

10.9.1

General

Electrical cabinets can be cooled, using among other things with the following:
● filtered fans
● heat exchangers or
● cooling units.
The decision in favor of one of these methods depends on the prevailing ambient conditions
and the cooling power required.
The air routing inside the control cabinet and the ventilation clearances specified here, must
be carefully observed. Other components or cables must not be installed/routed in these
areas.
You must comply with the following specifications when installing SINAMICS components:
● Cooling clearance
● Cable routing
● Air guidance, air-conditioner

The PM340 Power Modules can be mounted side by side without base components up to an ambient temperature of
1)
40° C. In combination with base components and at ambient temperatures of 40° C to 55° C, the specified lateral
minimum clearances must be observed. Where combinations of different frame sizes are concerned, the longer of the
two clearances shall apply.
