Power Input Wire Size, NFB and MCB Part Numbers
The following table shows the recommended wire size, molded case circuit breakers and magnetic contactors
for each of the A510 models. It depends on the application whether or not to install a circuit breaker. The NFB
must be installed between the input power supply and the inverter input (R/L1, S/L2, T/L3).
Note:
When using a ground protection make sure the current setting is above 200mA and trip delay time is 0.1
sec of higher.
