If you use a residual current device to protect the power line, in units with inverter, use type "B" or "B+"
residual current devices, with minimum tripping threshold of 300 mA and delayed tripping.
The electrical connections to potential-free contacts, which are powered by external sources, must be
suitably protected against overcurrent and earth faults.
