c.Disconnect the Phase B hot wire from the AC power source and place it through the hole in the Current Sensor such that the arrow on the Current Sensor points towards the AC power source. Then, reattach the Phase B hot wire to the AC power source.

Step 4: Install the third Current Transformer as follows:

a.Connect the black wire to pin 11 (IC+) on the ACM100

b.Connect the white wire to pin 12 (IC-) on the ACM100

c.Disconnect the Phase C hot wire from the AC power source and place it through the hole in the Current Sensor such that the arrow on the Current Sensor points towards the AC power source. Then, reattach the Phase C hot wire to the AC power source.

Step 5: You must supply a cable for connecting the voltage sense pins on the ACM100 to the AC source. For the purposes of these instructions, we will assume that the cable has one black conductor and one white conductor. Install the voltage sense cable as follows:

a.Connect the white wire from one end of the Voltage Sense cable to pin 4 (VANeutral) on the ACM100.

b.Connect the white wire from the other end of the Voltage Sense cable to the neutral wire of the AC source being monitored.

c.Connect the black wire from one end of the Voltage Sense cable to pin 1 (VALine) on the ACM100

d.Connect the black wire from the other end of the Voltage Sense cable to a fuse appropriately sized for the black wire (18 gauge wire minimum and 3 amp fuse or less).

e.Connect the other end of the fuse to the AC source hot wire (the fuse should be placed within 6 inches of the connection to the hot wire).

Step 6: Install the second Voltage Sense cable as follows:

a.Connect the white wire from one end of the second Voltage Sense cable to pin 5 (VBNeutral) on the ACM100.

b.Connect the white wire from the other end of the second Voltage Sense cable to the neutral wire of the AC source being monitored.

c.Connect the black wire from one end of the second Voltage Sense cable to pin 2 (VBLine) on the ACM100

d.Connect the black wire from the other end of the second Voltage Sense cable to a fuse appropriately sized for the black wire (18 gauge wire minimum and 3 amp fuse or less).

e.Connect the other end of the fuse to the AC source hot wire (the fuse should be placed within 6 inches of the connection to the hot wire).

Step 7: Install the third Voltage Sense cable as follows:

a.Connect the white wire from one end of the second Voltage Sense cable to pin 6 (VCNeutral) on the ACM100.

b.Connect the white wire from the other end of the second Voltage Sense cable to the neutral wire of the AC source being monitored.
