6.5.1 External coupling devices (AGH: no)
Basic setting "no", when no coupling device is used (factory setting).
AGH: 204 AK80
Terminal AK of the IRDH275 is connected to terminal AK80 of the
AGH204S-4. The nominal voltage range is extended to 3AC 0…1650 V. Only
current converters with an output voltage not exceeding DC 1000 V are al-
lowed to be connected (see "operation with coupling device" on page 34).
AGH: 520S
Terminal AK of the IRDH275 is connected to terminal 5 of the AGH520S. The
nominal voltage range is extended to AC 0…7200 V. Only current converters
with an output voltage not exceeding DC 1000 V are allowed to be connected.
AGH: 204 AK160
Terminal AK of the IRDH275 is connected to terminal AK160 of the
AGH204S-4. The nominal voltage range is extended to 3AC 0…1300 V. Only
current converters with an output voltage not exceeding DC 0…1840 V are al-
lowed to be connected (see page 34).
AGH: 150 AK160
Terminal AK of the IRDH275 is connected to terminal AK160 of the
AGH150W-4. The nominal voltage range is extended to DC 0…1760 V.
The coupling monitoring is deactivated when an external
coupling device is connected.
