SAFETY INSTRUCTIONS
The system described in this manual is for exclusive operation by trained employees. Only qualified
personnel that know the potential dangers involved should perform the installation, settings,
maintenance and repair of the units used.
Operational Safety
The correct and safe use of these systems assumes that operating and service personnel follow the
safety measures described in the manual alongside the generally acceptable safety procedures.
If there is a possibility that safe operation cannot be guaranteed the system must be switched off and
secured against accidental use. Then the service unit responsible must be informed.
Safety Documents
This ILR system was designed, tested and supplied in perfect condition according to document IEC348
Safety Requirements for Electronic Units of Class 1.
Condensation/Change of Temperature
Moving the systems from a cold to a warm environment could lead to dangerous situations due to
condensation. Therefore it must be ensured that the system can adjust itself to the warmer
temperature.
Do not open the housing
There is no need to open the housing in order to set any ILR unit. No unit has any internal setting
elements or displays. All settings are performed using software via the Service Interface.
Earthing
Before establishing any connections the housing of the system must be earthed.
Connections / Power Supply
The mains power supply must be equipped with an easy and safely accessible remote emergency cut-
off switch. The mains power supply must be equipped with an over-current protective device that
limits current to 16 A.
During maintenance, damage could occur if printed circuit boards or cables are connected or
disconnected whilst the power supply is still on. Therefore only work on the connection and the
components when they are not live.
The power supply circuit must comply with the requirements of the SELV circuits (see EN 60950).
The signal circuits must comply with the requirements of the SELV circuits (see EN 60950).
The RS422/i-BUS signal circuits must comply with the requirements of the TNV-1 circuits (see EN
60950).
