Insulation monitor - GMWISO 1.05− Before insulation or voltage tests are carried out at the stand-by electric-powergenerators (for example in the case of high-voltage tests/earth contact tests) orat parts of the installation, the GMWISO insulation monitor must be separatedfrom the generator and all parts of the installation for the duration of the test.− In each electrically connected distribution system only one insulation monitor maybe connected (i. e. in the case of an insulation monitoring with GMWISOinsulation monitor at the generator, socalled "Solid-rubber distributors" or similarwith insulation monitor are not admissible!) because insulation monitors can havean influence on each other.− It is possible to connect D.C. powered devices (solenoid valves, brakes,converters etc.) in the network of the stand-by electric-power generator to bemonitored. It must be taken into account, however, that faulty insulation in theD.C. circuit is registered with an increased sensitivity in both current directions.− Distributions and devices with built-in residual current operated devices are notfail-safe with ungrounded, portable stand-by electric-power generators (due tothe missing grounding installation/potential segregation), but they are notnecessary when the system of protection "potential segregation with insulationmonitoring and cut-off" is used.− If the GMWISO insulation monitor is used within the scope of GW308 a briefoperator's guide for the insulation monitoring must be attached at the stand-byelectric-power generator pointing out the daily functional test.− Further inforination and regulations for the use of generators with the system ofprotection "Fuse disconnection with insulation monitoring and cut-off" can befound in VDE 0 100, part 728 and GW 308.− Additional provisions or regulations limiting the operation of the generator in thecase of particular operating conditions (for ex. rules for prevention of accidents/VBG, VDE 0706, conditions by the (German) employer's liability insuranceassociation or similar) must be taken into account.6GTS GmbH & Co.

Insulation monitor - GMWISO 1.05Warnings and informations on generatots with GMWISOSince the stand-by electric-power generators equipped with the system ofprotection "Fuse disconnection with insulation monitoring and cut-off" have mainlybeen conceived for the use by non-electricians, it must be possible for all users ofthe stand-by electric-power generator to safely operate the stand-by electric-powergenerator and to test the additional safety measure against direct contact. Bothmust be identified at the device.At least the following instructions must be attached visibly and permanently to theelectric-power generator.COMMENT: Depending on the electric-power generator or its purpose, it might benecessary to attach or enclose further instructions. The exemplary text refers tothe operation of the GMW-SYNCHRO stand-by electric-power generator.Short operator's guide/information− Used safety measure: "Fuse disconnection with insulation monitoring and all-poloCut-off".− This device can be operated without grounding.− The following tests must be carried out daily with the motor running:1. Unplug all devices; open the cover; safety switch in position "ON",2. press the test button,3. check whether the safety switch has triggered and the signal lainp has beenactivated,4. stop the electric?power generator,5. safety switch in position "ON", close the cover.− NOTICE: The electric-power generator may only be used if the safety switchtriggered during the test.− The total length of all lines connected to the electric-power generator mustntexceed 250 m.− If several stand-by electric-power generators are used or if the general networkis also available, the networks mustn't be connected to each other.− Corrective maintenance at the electrical components of the stand-by electricpower generator and at the electric equipment may only be carried out byelectricians.− For further safety and operating inforination, please refer to the Operator'sGuide and the relevant regulations.GTS GmbH & Co.
