NOTE:
Connect 100:5 current transformer leads to current shunt at terminals #16 and #18. Use
16AWG wire and keep it shorter than 10 feet to avoid losing signal strength. If the current trans-
former is further away than 10 feet it may be necessary to use larger wire size or mount the current
shunt next to the current transformer and then connect the shunt to the AC controller using #18AWG
shielded cable.
Motor speed controllers with 0-5 Vdc output load monitor may be connected to terminals #17 and
#18 using shielded cable.
A small, 10μF, capacitor may be needed at the far end of the cable for recorder output to suppress
electrical noise signals. The near end of the shield (screen) should be connected to the rear of the
AC chassis green screw terminal.
