1.2 Wiring
Warning
 Always turn OFF the power supply before attempting inverter installation and wiring of
the user terminals.
 Wiring must be performed by a qualified personnel / certified electrician.
 Make sure the inverter is properly grounded. (200V Class: Grounding impedance shall
be less than 100Ω. 400V Class: Grounding impedance shall be less than 10Ω.)
 Make sure the inverter is properly grounded. It is required to disconnect the ground wire
in the control board to avoid the sudden surge causing damage on electronic parts if it is
improperly grounded.
 RCD is required to be in compliance with the protection norm of B-type leakage current.
 Please check and test emergency stop circuits after wiring. (Installer is responsible for
the correct wiring.)
 Never touch any of the input or output power lines directly or allow any input of output power
lines to come in contact with the inverter case.
 Do not perform a dielectric voltage withstand test (megger) on the inverter this will result in
inverter damage to the semiconductor components.
Caution
 The line voltage applied must comply with the inverter’s specified input voltage. (See
product nameplate section 2.1)
 Connect braking resistor and braking unit to the designated terminals. (See section 3.10)
 Do not connect a braking resistor directly to the DC terminals P (+) and N (-), otherwise fire
may result.
 Use wire gauge recommendations and torque specifications. (See Wire Gauge and Torque
Specification in section 3.6)
 Never connect input power to the inverter output terminals U/T1, V/T2, W/T3.
 Do not connect a contactor or switch in series with the inverter and the motor.
 Do not connect a power factor correction capacitor or surge suppressor to the inverter
output.
 Ensure the interference generated by the inverter and motor does not affect peripheral
devices.
