Config ration and installation of the device sho ld be carried o t by personnel with the
necessary a thorizations and q alifications in the scope of operation, maintenance, assembly of
devices and installations of power networks.
The device sho ld be installed in cabinets or facilities where access is limited only for q alified
personnel. The following notes sho ld be observed d ring installation.
 The device should be installed in cabinets or facilities where access is limited only for
qualified personnel. The following notes should be observed during installation.
The power cable should always be connected to a power source with the possibility of 
earth connection to the grounding screw terminal.
 It is not permissible to use earthing and zeroing simultaneously via the mains supply
cable.
 Dual fuse - pole/zero. Each power cord (L, N) is protected by a separate fuse located
inside the unit. If only one of the fuses is damaged, other components may remain live.
 Some parts of the power supply unit located on the PCB are located on the mains
potential.
 To avoid contact with live components, always disconnect the power supply before
removing the housing cover.
 The device does not have a built-in disconnecting system. Such a system should be
located outside the device.
In the case when the device is powered from 230 V mains, the plug on the power cord serves
as a disconnecting element and the plug socket should be located near the device and be
easily accessible for service.
The manufacturer is not responsible for any events arising from the use and installation of
the device not in accordance with the operating instructions.
The user's manual is an integral part of the device and is handed over to the users with it.
