24V Logic A user–supplied 24V ac rms or 24V
dc power source. Refer to your 1394
documentation for 24V input power
specifications. 3.3 mm 2
(12 AWG)
J1–1 and J1–2 Y
360/480V ac
Input Power 360/480V ac, three–phase power
input. Make sure to bundle your
three–phase power together with
neutral as much as possible. Refer
to your 1394 documentation for
system specifications for rated ac
input voltage, tolerance, and source
impedance. 5.3 mm 2

Important: Refer to your 1394 documentation for information about
three–phase input fusing and circuit breaker information as related to the
power input. Refer to the same documentation for information about
wiring the optional shunt resistor to the 5 and 10 kW system modules.
