Address Setting And Termination; Intended Use - Bender ISOMETER isoHR1685DW-925 Manual

Safety instructions
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 ap-
plication 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 fre-
quency components above the specified frequency range, e.g. within the
range of typical switching frequencies of frequency converters
(2...20 kHz).

2.4 Address setting and termination

Correct address setting and termination is essential for proper functioning of the
isoHR1685D-925 series insulation monitoring device.
Risk of bus errors!
Double assignment of addresses on the respective BMS busses can cause
serious malfunctions.
CAUTION
Ensure correct address setting and termination of the device!

2.5 Intended use

Only qualified personnel are permitted to carry out the work necessary
to install, commission and run a device or system.
Read the operating manual before starting to install, connect and com-
mission the device. After successful commissioning, keep the manual
within easy reach for future reference.
The device is used for monitoring the insulation resistance in large power supply systems
designed as IT systems. The specific measurement method (AMP
tion resistance also in installations where extremely high system leakage capacitances to
earth exist due to interference suppression methods. The adjustment even to high sys-
tem leakage capacitances occurs automatically.
The device generates locating current pulses required for insulation fault location. That
allows the localisation of the insulation fault using permanently installed or mobile insu-
lation fault locators.
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 set-
tings must be made on the equipment in order to adapt it to local equipment and oper-
ating conditions. Please heed the limits of the area of application indicated in the
technical specifications.
Any other use than that described in this manual is regarded as improper.
