4. INSTALLATION
4.1
Indoor unit:
General installation and placement tips:
•
Ensure that the ambient temperature around the indoor unit is not
affected by lamps, radiators, doors or windows, drafts, etc..
•
For hanging use: hang the unit free from obstructions, i.e. not behind a
curtain, for example.
•
Make sure that the adapter cable cannot lead to falls or tripping.
Secure the cable with cable ties if it is too long.
Power supply:
The main power of the indoor unit is provided by the supplied power
adapter. Insert the low voltage plug of the adapter into the DC5.0V
connection on the right side of the indoor unit and connect the adapter to a
230V socket.
As a backup, to save the measurement data during a possible power failure
or if the adapter is accidentally unplugged, 3 pcs 1,5V AAA batteries can
be inserted. The light intensity setting will revert to the lowest setting after
5 seconds to increase battery life.

note:
Due to poor or non-performance of normal Alkaline batteries at
temperatures around or below 0°C, the use of standard Alkaline
batteries is not recommended for the outdoor unit. For the outdoor
units, we, therefore, recommend installing Lithium batteries which are
designed to function within a temperature range of -20°C to 60°C.
These batteries are available through the Alecto service department
on telephone number 073 6411 355 (Netherlands) or 03 238 5666
(Belgium) or via the internet www.alecto.nl.
The battery life of Lithium batteries with a capacity of 900 mAh is more
than a year.
