E-Mail: info@bender-service.com • www.bender.de Although great care has been taken in the drafting of this operating manual, it may nevertheless contain error and mistakes. The Bender group cannot accept any liability for injury to persons or damage to property resulting from errors or mistakes in this manual.
1.2 Explanation of symbols and notes The following terms and symbols are used to denote hazards and instructions in Bender documentation: This signal word indicates that there is a high risk of danger that will result in electrocution or serious injury if not avoided.
In case of doubt, please contact a Bender product manager. An EDS system consists of the insulation fault locators EDS460/490 or EDS461/ 491 and either the A-ISOMETER® IRDH575 or locating current injector PGH. Using measuring current transformers, EDS460/490 or EDS461/491 insulation fault locators detect locating current signals generated by the IRDH575 insu- lation monitoring device or PGH…...
2.2 Qualified personnel Only skilled persons may work on Bender devices. Personnel who are familiar with the assembly, commissioning and operation 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.
Safety instructions 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.
Fast insulation fault location is possible with EDS systems. 3.1.3 System versions EDS460, EDS461, EDS490 or EDS491 insulation fault locators differ in their re- sponse sensitivity and/or number of alarm relays. 3.1.4 System features Universal system concept;...
