5.4 Connection diagrams
Note the following information and select the correct connection diagram for the relevant
version.
Residual-current-operated protective devices
For ECblue 3 ~ types and when connecting 1 ~ types between two outer conductors, only all-current
sensitive fault current circuit breakers (type B) are allowed (see EN 50 178, Art. 5.2).
UL: Input (Line)
Copper connecting leads with an insulation temperature of at least 80 ° C must be used!
Initialisation time for relay
After switching on the line voltage, an initialisation time of a maximum 7.5 seconds is required for the
device's electronics to be operational. Subsequently, a reliable status message will be possible. If no
malfunction is detected, the relay will be energised after the initialisation time.
