ATTENTION
The -F version of the product is not suited for 3-wire connection. It has separate
grounds for power supply and analogue output. Connecting both grounds
together might result in incorrect measurements. Minimum 4 wires are required
to connect -F type sensors.
The -G version is intended for 3-wire connection and features a ‘common ground’.
This means that the ground of the analogue output is internally connected with
the ground of the power supply. For this reason, -G and -F types cannot be
used together on the same network. Never connect the common ground of -G
type articles to other devices powered by a DC voltage. Doing so might cause
permanent damage to the connected devices.
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.).
ATTENTION
Mount the sensor in a well-ventilated area, where it receives adequate airflow
for proper operation and hide it from direct sunlight. Make sure it can be easily
accessed for service.
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 cables through the opening on the rear plate (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
