Electromechanical control
EMC-compliant installation of control cables
To avoid interference, ensure there is sufficient clearance between the mains power and control cables. When using a shiel-
ded cable, make sure that the shield is connected just on one side, i.e. only to the signal source with the protective earth (as
short and low inductance as possible)!
Fig. 13: Install the motor junction box.
Unscrew the screw in the bracket of the motor junction
box and remove the motor junction box from the area of
the intake crown.
Loosen screws in the cover of the motor junction box and
remove the cover.
Carry out the electrical wiring.
Commission the unit.
Close the motor junction box and refit it to the Ultra. As-
semble in reverse order to dismantling.
Important:
After completion of the electrical wiring, do
not push the cables through the motor guard close to the
fan!
