Residual Current Monitoring
Residual-current monitoring relays

Residual current monitoring with Manual RESET (Memory = yes)
If Manual RESET is selected in the menu, the output relays re-
main in their current switching state and the current measured
value and the symbol for overshooting continues to flash, even
when the measured residual current returns to a permissible
value. This stored fault status can be reset by pressing the UP

and DOWN
▼
keys simultaneously for > 2 seconds, or by switch-
ing the supply voltage off and back on again.
Note:
Do not ground the neutral conductor downstream of the residual-
current transformer as otherwise residual current monitoring
functions can no longer be ensured.
