1.1 How to use this manual
This operating manual describes EDS460/490 bzw. EDS461/491 insula-
tion fault evaluators. It is designed for skilled personnel working in elec-
trical engineering and electronics and in particular for those designing,
installing and operating electrical systems.
Before using the equipment, please read this operating manual, the sup-
plement entitled "Important safety instructions for BENDER products",
the "BMS bus" instruction leaflet, as well as the instruction leaflets sup-
plied with the individual system components. Please keep this docu-
mentation close at hand near to the equipment.
Should you have any questions, please do not hesitate to contact our
technical sales team. We are also happy to provide on-site services.
Please contact our Service Department for more information.

2. Safety instructions
2.1 Intended use
EDS... insulation fault location systems have been designed to monitor
unearthed DC, AC and three-phase power supply systems (IT systems)
for insulation faults. Alternating and three-phase systems in the range of
AC 24 to 690 V and DC systems in the range of DC 24 to 500 V can be
monitored. The operating frequency is optionally DC, 50, 60 or 400 Hz.
The nominal system voltage varies with the type of insulation fault test
device used (PGH47., IRDH575).
An EDS system consists of the insulation fault evaluators EDS460/490 or
EDS461/491 and either the A-ISOMETER® IRDH575 or insulation fault
test device PGH. Using measuring current transformers EDS460/490 or
EDS461/491 insulation fault evaluators detect test current signals gener-
ated by the RDH575 insulation monitoring device or PGH... insulation
fault test device and evaluate them.
If the test current is too high, IRDH575 or PGH... may dam-
age sensitive loads (e.g. in control circuits) or may acci-
dentally activate switching operations. Therefore, it is
recommended to use a PGH... with a low test current or to
set a low test current at the IRDH575. The response sensi-
tivity of EDS461/491 insulation fault evaluators is higher
and hence they are capable of evaluating this low test
current.
In case of doubt, please contact a BENDER product man-
ager.
Caution
Safety instructions
10 TGH1394en/05.2007
Up to 12 measuring current transformers can be connected to one
EDS.... Up to 90 EDS... evaluators can be connected via a BMS bus (RS-
485 interface with BMS protocol), thereby up to 1080 measuring chan-
nels (sub-circuits) can be monitored. The scanning time for all channels
is approximately 4…10 s.
The individual parameterization, necessary to adjust the evaluator to the
existing system and utilization conditions, must be carried out at the
place of utilization in order to meet the requirements laid down in the
standards.
Please take note of the limits for the application area specified in the
technical data. Any other use, or use which goes beyond the foregoing
is deemed to be use other than for the intended purpose.
Use for the intended purpose also includes:
The observation of all information in this operating manual.
and the compliance with test intervals.
2.2 Qualified personnel
Only suitably qualified personnel may work on BENDER devices. Per-
sonnel who are familiar with the assembly, commissioning and opera-
tion of the equipment and have undergone appropriate training are
considered qualified. Such personnel must have read this manual and
understood all instructions relating to safety.
2.3 Safety information
BENDER devices are built in accordance with the state of the art and
accepted rules in respect of technical safety. Nevertheless, the use of
such devices may introduce risks to the life and limb of the user or third
parties and/or result in damage to BENDER devices or other property.
Only use BENDER devices:
– for the purpose for which it is intended;
