Relay in 3-phase main monitors size of phase voltage. It is possible to set two independent
voltage levels and thus it is possible to set two independent voltage levels and monitor
e.g. undervoltage and overvoltage independently. In normal state when voltage is
within set levels, output relay is closed and red LED shines. In case voltage exceeds or
falls below the set levels, output relay breaks and red LED shines (LED indicates faulty
state - fl ashes when timing). In case of In case supply voltage falls below 60 % Un (U
lower level) relay immediately breaks without delay and faulty state is indicated by
red LED. In case timing is progress and faulty state is indicated, timing is immediately
stopped.
Warning
Device is constructed for connection in 3-phase 400 / 230 V main alternating current voltage
and must be installed according to norms valid in the state of application. Connection
according to the details in this direction. Installation, connection, setting and servicing
should be installed by qualifi ed electrician staff 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 degree (A, B, C) installed in front of them. According
to standards elimination of disturbancies must be ensured. Before installation 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 temperature of the device is not exceeded. For installation and
setting 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
transportation, storing and handling. In case of any signs of destruction, deformation,
nonfunction 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.
