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.

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.

supplied screw at marking [M]. 3 x 10 mm
screw is secured in the internal cover with
sticky tape.
