Operating the product
The product to be supplied with power must be fitted to the
window and connected to the power supply unit.
Subsequently, the following three installation steps must be
completed in order to operate the product:
1. Connect the power supply unit to the mains supply.
2. Insert the batteries into the wall switch delivered with the
product to be supplied with power.
3. Press the down arrow to complete the installation.
Wiring
Lead the connecting cable from the power supply unit to the
window. Wiring in roof windows is described in the instructions
for wiring supplied.
The 8 m long cable has a cable cross-section of 2 x 0.75 mm
2
.
If necessary, it can be extended by up to 12 m using the same
cable type (max total length: 20 m). If the cable must be longer
than 20 m, the cable supplied must be replaced by a cable with
a cable cross-section of 2 x 1.50 mm
2
(max total length: 50 m).
Connecting products to a power supply unit
When connecting more than one product, lead the cable to
a junction box from where the cables are distributed to the
individual products. The junction box should be placed as close
as possible to the products to be supplied with power.
Connecting products to additional power supply
units
When installing more than one power supply unit, use a
separate 2-core cable for each power supply unit. Do not use
multicore cables as the signals between the power supply units
and connected products may be disturbed.
Important
The polarity (+/-) must be kept all the way through to the
product.
