7.7 Main connection
The circuit breaker can either be fed from the upper or the lower connection terminals.
Changing the infeed connection has no effect on the technical specifications of the
circuit breaker.
Note
Installation of voltage taps when metering function is configured
If a metering function is configured, the voltage taps
should be installed on the infeed
side. This means that information about the operational voltage is still available when
the circuit breaker is open.
