1. How to use this operating manual effectively

1.1 How to use this manual

This operating manual describes EDS460-DG insulation fault evaluators.

It is intended for skilled personnel in the areas of electronics and elec-

trical engineering but, in particular, for planners, installers and opera-

tors of 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 the equipment.

Should you have any further questions, we would be happy to be of as-

sistance. Please contact our technical sales team. We also offer a wide

range of on-site services. Contact our Service Department for further de-

tails.

2. Safety information

2.1 Intended use

EDS460-DG insulation fault evaluators are used to localise insulation

faults in unearthed DC power supply systems (IT systems). DC systems

of DC 20...308 V can be monitored.

An EDS system consists of EDS460-DG insulation fault evaluators and

IRDH575 A-ISOMETER® or PGH insulation fault test device. Using

measuring current transformers, EDS460-DG insulation fault evaluators

detect test current signals generated by the IRDH575 insulation moni-

toring device or by the PGH... insulation fault test device and evaluate

them.

Up to 12 measuring current transformers can be connected to one

EDS460-DG. Up to 90 EDS460-DG evaluators can be connected via a

BMS bus (RS-485 interface with BMS protocol), thereby up to 1080

measuring channels (sub-circuits) can be monitored. The scanning time

for all channels is approximately 4…10 s.

Using the IRDH575 or PGH... with a high test current may

damage sensitive loads (e.g. in control circuits) or may

accidentally 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. In case of doubt,

please contact a BENDER product manager.

Caution

Safety information

10 TGH1429en/10.2008

Individual parameterisation, necessary to adjust the evaluator to the ex-

isting system and utilisation conditions, must be carried out at the place

of utilisation in order to meet the requirements laid down in the stand-

ards.

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.

Intended use also implies:

 The observation of all information in this operating manual.

 Compliance with test intervals.

2.2 Skilled persons

Only skilled persons may work on BENDER products. Personnel who

are familiar with the assembly, commissioning and operation of the

equipment and have undergone appropriate training are considered

qualified. Personnel must have read and understood the safety section

and warning information in this operating manual.

2.3 General safety information

BENDER equipment is designed and built in accordance with the state

of the art and accepted rules in respect of technical safety. However, 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 equipment or other

property.

 Only use BENDER equipment:

– for the purpose for which it is intended;

– when it is in perfect condition as far as safety is concerned;

– in accordance with the rules and regulations on accident preven-

tion that are applicable for the place of utilisation.

 Any faults which may impair safety must be eliminated immediately.
