Does output 4 (O4) need to be wired for proper protection in SEPAM 20 and 40 series?

O4 does not need to be wired for the SEPAM 20 and 40 series to provide proper protection. O4 is used as a watchdog only. O4 acts as a malfunction detection output such that if a fault occurs in the relay it will be detected. The relay will then open the circuit breaker and enter fault mode.
