NOTICE: Isolate control circuit wiring from main circuit wiring (terminals R/L1, S/L2, T/L3, B1, B2, U/T1, V/T2, W/T3, -, +1, +2)
and other high-power wiring. Incorrect wiring procedures could cause drive malfunction because of electrical interference.
NOTICE: Isolate contact output terminals MA, MB, MC and M1-M6 from other control circuit wiring. The drive and connected
equipment will malfunction or the drive can trip because of incorrect wiring.
NOTICE: Use a class 2 power supply when connecting to the control terminals. Refer to NEC Article 725 Class 1, Class 2, and
Class 3 Remote-Control, Signaling, and Power Limited Circuits for requirements concerning class 2 power supplies. Improper
application of peripheral devices could result in drive performance degradation due to improper power supply.
NOTICE: Insulate wire shields with tape or shrink tubing to prevent contact with other signal lines or equipment. Incorrect wiring
procedures could cause the drive or connected equipment to malfunction because of short circuits.
NOTICE: Connect the shield of shielded cable to the applicable ground terminal. Incorrect equipment grounding could cause
