Note 1. The standard model does not have the S2, S3, PA, PC, AM, or AC terminal.
Note 2. The sequence input and the sequence output can be wired with a single shielded cable.
3-2-2 Wiring Around the Main Circuit
System reliability and noise resistance are affected by the wiring method used. There-
fore, always follow the instructions given below when connecting the Inverter to periph-
eral devices and other parts.
H Wire Size
For the main circuit and ground, always use 600-V polyvinyl chloride (PVC) cables.
If the cable is long and may cause voltage drops, increase the wire size according to the cable length.
