WIRING
Refer to the following table for the external terminal designations.
Wiring Connection Notes:
1. To prevent noise, use shielded wire as specified in Fig.4.
2. Separate the power wiring circuits (200VAC or greater) and relay wiring circuits (120VAC) from the
control wires.
3. Wire lengths must be 164 feet (50 meters) or shorter.
4. Connect the AO-12B2 grounding lead wire (E) to the inverter control board’s grounding terminal 12.
5. Applicable wire sizes for terminal block TBI are as listed in the following table.
Stripping TB1 Signal Wires for Connection:
The following shows the correct length of insulation to be stripped in order to connect the wire to the Ter-
minal Blocks TB1 Cable Selection:
1. Cable too heavy exerts pressure on the Option Card and could cause failure.
2. Cable too thin could cause a poor connection or prematurely break or overheat.
