It continuously monitors the insulation resistance of AC or three-phase AC systems (IT systems) with a rated system voltage range of AC\/3(N)AC 0…793 V . In combination with AGH series coupling devices, the nominal voltage can be extended to higher levels . An external supply voltage allows de‑energised systems to be monitored as well .
