External input protection
The device is tested and approved for circuits up to 30 A (UL) and 32 A (IEC). External protection is only
required if the supply line has a protection that is higher than this. Also check the local regulations and
requirements. Local regulations may apply in some countries.
If an external fuse is required or used, minimum requirements must be taken into account to avoid false
tripping of the circuit breaker.
• A circuit breaker with a minimum value of 6 A with B or C characteristic should be used.
