18 AWG (0.75 mm
2
minimum)
DC Power Supply The external wiring to this connector must be at a minimum 1.5 mm² (14 AWG)
with a 15 A fuse or circuit breaker. A 20 A circuit breaker may be used if the
external wiring is jacketed 14 AWG, with maximum length of 20 feet. An
internal fuse mounted on the power supply carrier board is included to protect
this input but is not field replaceable. Mating connector for the DC power
supply is a AMP 1-350344-0 and 2 sockets are required, AMP 350388-1.
