Application

The KWL EC 45 is controlled via the KWL 45 BEU controller, up to eight units can be connected to one KWL 45 BEU
(note wiring diagrams SS-1091 or SS-1093).
– Normal use:
The control set and its components are only approved for fixed installation inside buildings in a flush-mounted box or in
a control cabinet . The maximum permissible ambient temperature can be found on the type plate.
– Reasonably foreseeable misuse:
The units are not suitable for operation under difficult conditions, such as high levels of humidity, aggressive media,
long standstill periods, heavy contamination, excessive loads due to climatic, technical or electronic influences. The
same applies for the mobile use of fans (vehicles, aircraft, ships, etc.). Usage under these conditions is only possible
with release approval from Helios, as the standard version is not suitable in this case.
– Improper, prohibited use:
Any use other than the intended use is not permitted!
1.4
