NOTE
All electrical connections must be carried out
by an authorised electrician.
Electrical installation and wiring must be carried
out in accordance with the stipulations in force.
The climate unit must not be powered when
installing ECS 40/ECS 41.
• To prevent interference, sensor cables to external
connections must not be laid close to high voltage
cables.
• The minimum area of communication and sensor
cables to external connections must be 0,5 mm² up
to 50 m, for example EKKX, LiYY or equivalent.
• ECS 40/ECS 41 must be installed via an isolator
switch. The cable area has to be dimensioned based
on the fuse rating used.
• Mark the relevant electrical cabinet with a warning
about external voltage, in those cases where a com-
ponent in the cabinet has a separate supply.
• ECS 40/ECS 41 restarts after a power failure.
