10. Connect the unit electrically
 wiring diagrams on page 21...24.
Cut off and insulate PE
conductor and individual cable
cores that are not required!
Wire up electrics for fan on terminal
block [5] and for shutter on terminal block
[6]  relevant wiring diagram. With
airstream-operated Maico AS shutter,
there are no connections on terminal
block [6].
The degree of protection is only
guaranteed if the cables are fed
through correctly using the inten-
ded cable grommets [T1]...[T5].
11. Check protective-conductor opening on
housing.
12. Attach terminal box cover [2] and screw
down (tightening torque of the 3 screws
is 1 Nm each)  Fig. 2H. Ensure the
sealing [2.1] is fitted correctly.
13. If necessary, connect a speed controller
(ST, STU, STS) or frequency converter.
The technology used in the
phase angle controller may
cause humming noises. If using a
frequency converter, you may
need to use a mains filter.
14. Fit internal cover [1]. To do this, hang
internal cover [3] on the top of the
connecting flange [3], swivel down and
clip it into place in the safety catch. Do
not twist it.
15. Switch the mains fuse on. Run function
test.

2. Drill through the internal cover [1] at
position [B] carefully and with a suitable
drill bit (Ø 3.5 mm). The hole prevents
the build-up of damp and bacteria in
the fan housing. Observe dimensions.
3. Secure the internal cover [1] with the
supplied screw at marking [M]. 3 x 10 mm
screw is secured in the internal cover with
sticky tape.
10.3 Mounting on pitched roofs
(not shown)
See Chapter 10.2, Ceiling mounting.
11. Cleaning
Clean fan with dry cloth only. If necessary,
use a vacuum cleaner. If possible, swivel the
lamellae upwards to clean the shutter.
Do not use aggressive, harmful or easily
flammable cleaning agents for cleaning work.
