Warning
Device is constructed for connection in 1-phase
main alternating current voltage and must be in-
stalled according to norms valid in the state of
application. Connection according to the details
in this direction. Installation, connection, setting and servic-
ing should be installed by qualied electrician sta only, who
has learnt these instruction and functions of the device. This
device contains protection against overvoltage peaks and
disturbancies in supply. For correct function of the protection
of this device there must be suitable protections of higher de-
gree (A, B, C) installed in front of them. According to standards
elimination of disturbancies must be ensured. Before installa-
tion the main switch must be in position “OFF” and the device
should be de-energized. Don´t install the device to sources of
excessive electro-magnetic interference. By correct installation
ensure ideal air circulation so in case of permanent operation
and higher ambient temperature the maximal operating tem-
perature of the device is not exceeded. For installation and set-
ting use screw-driver cca 2 mm. The device is fully-electronic
- installation should be carried out according to this fact. Non-
problematic function depends also on the way of transporta-
tion, storing and handling. In case of any signs of destruction,
deformation, non-function or missing part, don´t install and
claim at your seller it is possible to dismount the device after its
lifetime, recycle, or store in protective dump.
Internal circuits and sensor circuits are not galvanically isolated
from the mains. No product circuits, including sensor circuits,
can be considered as ELVs.
Cable shield to the sensor, fullls a functional purpose in terms
of EMC does not fulll any protection or safety function and it
is not associated with any EP protection. It is not possible to
touch the shield as well as the other product wiring circuits!
Security against electric shock is ensured by reinforced insula-
tion product, cable, sensors and their correct and professional
installation.
The cable must be of a suitable dimension to meet the pa-
rameters to provide protection in the area of the over-voltage
category III.
