Technical parameters
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, 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.

Relay in 3-phase main monitors correct phase sequence and failure of any phase. Green
LED is permanently ON and indicates presence of power supply voltage. In case of phase
failure, red LED fl ashes and relay breaks. When changing to faulty state, time delay
applies. Time delay setting is set by a potentiometer on front panel of the device. In
case of incorrect phase sequence red LED shines permanently and relay is open. In case
supply voltage falls below 60 % Un (U
OFF
lower level) relay immediately opens with no
delay and faulty state is indicated by red LED.
HRN-55
: thanks to supply from all phases, this relay is able to stay operational also if one
phase is out.
HRN-55N
: supply L1, L2, L3-N, means that relay monitors also failure in neutral wire.
