If they are available, remote off switches (for optional use by customers) for disconnecting
the output-side breaker must be connected accordingly via the undervoltage coil.
The user should note and monitor the permissible number of switching cycles specified for
the output-side breaker. Once the permissible number of switching cycles has been
reached, it is imperative that breaker maintenance be carried out. Otherwise, it can no
longer be guaranteed that the breaker will function properly in the event of a fault.
