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.
