Notes:
1 . All wiring to be in accordance with National Electrical Code and any local codes.
2 . Refer to ship-with wiring schematics; some terminals may vary based on unit.
(a) For AWG/ MCM equivalents in mm

, refer to
Tab le 1 2 , p . 4 7 . Wires, lugs, and fuses/ breakers are sized based on National Electric Code NEC [ NFPA 70]
and UL 1995.
(b) Refer to submittal and ship-with wiring schem atics for voltage requirements.
(c) Solid State Starter Fault input is used with low-and medium-voltage, custom er-supplied solid state starters only.
(d) Must be separated from 120 Vac and higher wiring.
