3.2.6 Control Circuit Wiring
(1) Wiring Precautions
CM and 5G terminals are isolated from each other.
Digital Input Terminals are rated 24 VDC. Do not apply 120 Vac directly to control circuit input terminals.
Use shielded wires or twisted wires for all control circuit wiring, and separate these wires from the main
power circuits and other high voltage circuits (such as 120V relay circuits).
It is recommended to use wire sizes of 28 AWG to 16 AWG for TER1 and TER2 control terminals and 22
AWG to 14 AWG for TER3 and TER4 control terminals.
(2) Terminal layout
22 AWG – 14 AWG 28 AWG – 16 AWG
5G and CM
NOTE:
When using analog input terminals (V1, I) for speed reference, notice the difference between TER 1 ground
connections. For 40 HP and below, use the 5G terminal as the analog ground. For 50 HP and above, use the CM
terminal as the analog ground.
