• Do not connect any load other than a three-phase motor to the output side of the drive.
• Never connect a power source to the drive output.
• Never short or ground the output terminals.
• Do not use phase correction capacitors.
• Check the control sequence to make sure that the motor contactor is not turned ON or
OFF during drive operation. Turning on the motor contactor while voltage is output
causes an inrush current that is likely to trigger the drive’s overcurrent protection.
Note: The drive provides a Safe Disable function that can be used to reduce the number of
motor contactors to one. Refer to Safe Disable Input Function on page 50 for details.
Ground Connection
Take the following precautions when grounding the drive:
• Make sure the ground conductor complies with general technical standards and local reg-
ulations.
• Keep ground wires as short as possible.
• Always make sure the ground impedance is conform to the requirements of local safety
and installation regulations.
• Never share the ground wire with other devices such as welding machines, etc.
• Do not loop the ground wire when using more than one drive.
Control Circuit Wiring Precautions
Note the following precautions for wiring the control circuits:
• Separate control circuit wiring from main circuit wiring and other high-power lines.
• Separate wiring for control circuit terminals MA, MB, MC, and MD, ME, MF (contact
output) from wiring to other control circuit terminals.
• Use twisted-pair or shielded twisted-pair cables for control circuits to prevent operating
faults.
• Ground the cable shields with the maximum contact area of the shield and ground.
• Cable shields should be grounded on both cable ends.
• Note that flexible wires with ferrules may fit tightly into the terminals. To disconnect
them, grasp the wire end with a pair of pliers, release the terminal using a straight-edge
screwdriver, turn the wire for about 45 and pull it gently out of the terminal. Use this
procedure for removing the wire link between HC and H1 when the Safe Disable function
is utilized.

Sinking/Sourcing Mode (NPN/PNP Selection)
The input terminal logic can be switched between sinking mode (0-V common, NPN) and
sourcing mode (+24V common, PNP) for digital inputs S1 to S7 by setting jumper CN1. An
external power supply is also supported in both sinking and sourcing modes, providing more
freedom in signal input methods.
Internal Power Supply – Sinking Mode (NPN) (default) External Power Supply – Sinking Mode (NPN)
Internal Power Supply – Sourcing Mode (PNP) External Power Supply – Sourcing Mode (PNP)
