Note 1.
If a 3G3EV-AB
R is used in single-phase input mode, 200 to 240 VAC
power with a frequency of 50/60 Hz must be input between terminals R and S.
Note 2.
Use cabtire cables (VCTF 0.75 x 2C) to connect to the Remote I/O Master Unit.
3-2-2 Wiring Around the Main Circuit
System reliability and noise resistance are affected by the wiring method
used. Therefore, always follow the instructions given below when connect-
ing the Inverter to peripheral devices and other parts.
Wire Size and Molded-Case Circuit Breaker to be Used
For the main circuit and ground, always use 600-V polyvinyl chloride (PVC) cables.
