The unit needs to be supplied via the RJ45 connector or via the connection
terminals. Do not connect the device via the RJ45 connector and the terminal block
simultaneously!
MOUNTING & OPERATING INSTRUCTIONS IN STEPS
Before you start mounting the unit, read carefully
“Safety and Precautions”
.
Choose a smooth surface for installation (a wall, panel and etc.).
Follow these steps:
1.
Using a flat screwdriver, remove the front white cover by releasing the snap-fits
on its both sides (see
Fig. 1
Snap-fits release
).
2.
Insert the crimped RJ45 cable through the opening on the rear plate and plug it
into the socket (see
Fig. 2
Mounting dimensions
).
3.
Using suitable fastening materials (not supplied), position the room sensor at
least 1,5 m from the floor. When planning the installation, allow enough clearance
for maintenance and service. Mount the sensor in a well-ventilated area. Mind
the correct mounting position and unit dimensions. See
Fig. 2
and
Fig. 3
.
