This device is constructed for connection in 1-phase network AC/DC 12 – 240 V or AC
230 V (according to the type) and must be installed according to norms valid in the state of an application. Installation, connection, setting and servicing must be carried out
by qualified electrician staff only, which have perfectly understood the instructions and
functions of the device. This device contains protection against overvoltage peaks and
disturbing impulses in the power supply network. For the correct function of the protection of this device, there must be suitable protections of higher degrees (A,B,C) installed
in front of them and according to the standards, interference of switching devices must
be securely eliminated (contactors, motors, inductive loads, etc.). Before installation,
make sure that the device is de-energized and the main switch is in the “OFF” position. Don‘t install the device to sources of excessive electromagnetic interference. Ensure
correct installation by perfect air circulation so that during continuous operation and a
higher ambient temperature, the device does not exceed the maximum allowed operating temperature. For installation and setting use a screwdriver with a width of approx 2
mm. Keep in mind that this is a fully electronic device and approach accordingly with the
installation. Non-problematic function of the device is also dependent on the previous
method of transportation, storage, and handling. In case of any signs of damage, deformation, malfunction, or missing parts, don‘t install this device and claim it at the dealer.
The product must be treated as electronic waste at the end of its life.
