UK │ 9. Installation
NOTICE
Danger of short circuits and damage to
unit. Water will penetrate if the power
cable is incorrectly fed into the fan
housing or if the cable grommet is not
fitted correctly.
 Cut off cable grommet cap [3] such that
the cable grommet fits tightly round the
power cable. Cut off at least 5 mm of the
cap (power cable can bend better and
electronics cover [4] can be positioned
correctly).
 Fit cable grommet [3] correctly, seal on
both sides if required.
5. Insert cable grommet [3] into housing.
6. Guide power cable into connection area
such that the cable grommet
fits around the cable sheathing completely
and does not penetrate too far into the
connection area.

9.2 Electrical connection

NOTICE
Unit damage in the case of short-circuits.
 Insulate PE conductor and unneeded
cable cores.
 Do not touch electric components.
1. Switch off mains fuse, secure against
being accidentally switched back on and
position a warning sign.
2. Only lay single cable cores in the unit. To
do this, reduce power cable sheathing to a
length of 100 mm. Strip single cable cores
to 9 to 10 mm.

3. Insert housing [1] into wall breakthrough/
wall sleeve and secure with two screws.
Do not insert the housing such that it is
twisted or crushed. Make sure you use
mounting material which is sized for the
purpose.
4. Electrically connect power cable to spring
clip [13] according to connection wiring
diagram [14], also see wiring diagrams in
Chapter 15.
ECA 100 ipro standard model units
can be operated at two levels with
double switches. Without a double
switch, the fan can either be opera-
ted at performance level 1 or perfor-
mance level 2, see switch variants in
Chapter 15.
5. Check position of cable grommet. It must
be well sealed.
6. If necessary, connect a speed controller
(ST1, STU1).
The technology used in the phase
angle controller may cause
humming noises.
