1.2.2 About the operating manual This operating manual has been compiled with the greatest possible care. Nevertheless, errors and mistakes cannot be entirely ruled out. The BENDER companies assume no liability whatsoever for any injury to persons or damage to property which may be sustained as a result of faults or errors in this operating manual. -
Page 7: Inspection, Transport And Storage
Inspect the dispatch packaging and equipment packaging for damage, and compare the contents of the package with the delivery documents. In the event of damage in transit, please inform the BENDER company immediately. The devices must only be stored in areas protected from dust, damp and spray or dripping water, and in which the specified storage temperatures are maintained. -
Page 8: Directions For Installation
Safety information 1.4 Directions for installation Only one insulation monitoring device may be used in each intercon- nected IT system. When insulation or voltage test are to be carried out, the device shall be isolated from the system for the test period. The terminals and KE shall be connected by a separate wire to the protective conductor (PE). -

Page 10: Function
A microprocessor-controlled pulsating AC measuring voltage is superimposed on the AC system to be monitored (AMP measuring principle, "adaptive measuring pulse", developed by BENDER; European Patent: EP 0 654 673 B1). The measuring cycle consists of positive and negative pulses of the same amplitude. - Page 11 Function Self test In order to guarantee high functional reliability, the A-ISOMETER IR157x provides comprehensive self test functions. After switching the supply voltage on, all internal measuring functions, the components of the process control such as data and parameter memory as well as system and earth connections are checked using the self test functions.
