Air/air heat exchangers
3 - 14
Air/air heat exchangers in the external circuit should have a
distance of at least 200 mm from a wall and from one another
(air inlet and outlet openings).
If this distance cannot be met, air baffle plates should be
used.
Siting options
Wall-mounted heat exchangers may be mounted on the rear
panel, side panels or door of the enclosure.

Flow and siting conditions
It is important to ensure “even” air circulation inside the
enclosure. Air inlet and outlet openings in the internal circuit
must on no account be obstructed by electrical installations.
This would prevent air from circulating inside the enclosure.
Under such conditions, the capacity of the device would not
be adequately utilised. A clearance of > 200 mm must be
guaranteed.
Note:
Wall-mounted cooling units should never be fitted directly
behind the mounting plate. Active power components are
located on the front of the mounting plates. The heat
exchanger would then operate in its own air short-circuit.
If it is impossible to install the device any other way, appro-
priate air baffle plates should be used, and air inlet and out-
let openings should be provided in the mounting plate.
