EDR-3000 IM02602003E
Before Use
The sensitivity settings for the Maintenance Mode have to be calculated
and programmed into the device (according to Std. NFPA70E).
They are not part of the device by default.
When the Maintenance Mode is enabled and fault current causes its operation, the fault clearing time of the associated
breaker has to be very fast. Calculate the sensitivity setting on the basis of Std. NFPA70E.
Program those sensitivity settings either into a setting group or into Adaptive Parameters.

group or into Adaptive Parameters.

The »Maint Mode.
