The measurement results
of t
he device can be
negatively influenced by external factors. Possible
sources of interference are:
■ Draught and air movement:
e.g. through windows, doors, convection, heating and
people
■ Warming and cooling:
e.g. sunlight or mounting on an outside wall
■ Heat sources: close to installed electrical
consumers e.g. dimmers
■
Vibrations or shocks, whic
h the unites are
or were subjected to
■ Pollution due to colors, wallpaper paste,
dust e.g. at renovation work
■ Organic solvents or their vapours:
e.g. detergents
■ Plasticizers from stickers and packaging:
e.g. bubble wrap or polystyrene

 This device is suitable for wall mounting or for mounting on a flush-mounting box.
 The device should not be exposed to dusty environment.
 Ensure that no dust get inside of this device.
 After initial startup, the device requires up to 5 minutes until the first correct measurement is possible
STEP 1:
Open the device at the bottom and remove the front cover
.
STEP 2:
Mount the rear cover to the wall or on a flush
-
mounting box
STEP 3:
Connect the RS 485 Modbus serial cable and configure device according to the project
definition.
Afterwards connect the power supply
STEP 4:
After completing the installation the front cover
must
be reattached
Installation note:
Make
sure that no wires are pinched
or squeezed when
installing the cover.
The
mounting of the device on a flush
