2.4 Address setting and termination
Correct address setting and termination is essential for proper functioning of the device.
Ensure correct address setting and termination of the device!
2.5 Intended use
The device is used for the insulation monitoring of IT (i.e. unearthed) systems which need very fast signaling or
disconnection and a small leakage capacitance .
The measuring method, especially developed to provide a quick-release solution, monitors the impedance to
ground even in thyristor-controlled systems where the mains voltage is not purely sinusoidal.
Intended use also implies:
• The observation of all information in the operating manual
• Compliance with test intervals
In order to meet the requirements of applicable standards, customised parameter settings must be made on
the equipment in order to adapt it to local equipment and operating conditions. Please heed the limits of the
range of application indicated in the technical data.
Any use other than that described in this manual is regarded as improper.
Unspecified frequency range!
When connecting to an IT system with frequency components below the specified frequency
range, the response times and response values may differ from the indicated technical data.
However, depending on the application and the selected measurement method, continuous
insulation monitoring is also possible in this frequency range.
There is no influence on the insulation monitoring for IT systems with frequency components
above the specified frequency range, e.g. within the range of typical switching frequencies of
frequency inverters (2…20 kHz).
Risk of bus errors!
Double assignment of addresses on the respective BMS or CAN busses can cause serious mal-
functions.
Only qualified personnel are permitted to carry out the work necessary to install, commis-
sion and run a device or system.
