Wiring the Drive Control Circuit Terminal

WARNING! Electrical Shock Hazard. Do not remove covers or touch circuit boards while the bypass is energized. If you touch the
internal components of an energized bypass, it can cause serious injury or death.
NOTICE: Do not let wire shields touch other signal lines or equipment. Insulate the wire shields with electrical tape or shrink tubing.
If you do not insulate the wire shields, it can cause a short circuit and damage the drive.
Note:
• Isolate control circuit wiring from main circuit wiring (terminals R/L1, S/L2, T/L3, U/T1, V/T2, W/T3, -, +1) and other high-power wiring.
If the control circuit wires are adjacent to the main circuit wires, electrical interference can cause the drive or the devices around the drive to
malfunction.
• Isolate contact output terminals MA, MB, MC and M1-M6 from other control circuit wiring. If the output terminal wires are adjacent to
other control circuit wires, electrical interference can cause the drive or devices around the drive to malfunction.
• Use a UL Listed Class 2 Power Supply to connect external power to the contact output control terminals. If the power supply for peripheral
devices is incorrect, it can cause a decrease in drive performance.
• Connect the shield of shielded cable to the applicable ground terminal. If the grounding is not correct, electrical interference can cause the
drive or devices around the drive to malfunction.
