Branch Circuit Short Circuit Protection

The following peripheral devices may be required between the AC main circuit power supply and the Drive input terminals
L1(R), L2(S), and L3(T). Refer to applicable codes to determine the devices necessary for a given installation. Use Table E.1
or E.2 when selecting fuses and circuit breakers per the NEC. When selecting semiconductor fuses to provide Drive input I
protection and comply with UL, CSA, NEC, and CEC branch circuit short circuit protection requirements, select one of the
fuses in Table E.3 or E.4.
