Device is constructed for connection in 1-phase 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
qualified 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.
