In conjunction with an ISOMETER®, the AGH204S-4 coupling device is used for monitoring the insulation of 3AC IT systems (unearthed systems). It is designed to extend the nominal voltage range of the ISOMETER® series shown in the wiring diagram at terminal AK160 up to 3(N)AC 0…1650 V. At terminal AK80, it extends the range up to 3(N)AC 0…1300 V.
