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 (grounding impedance shall be less than
10Ω). 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.
➢
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 or output
power lines to come in contact with the inverter case.
➢
Do not perform a dielectric voltage withstand test (megger) on the inverter or 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).
➢
Braking resistor and braking unit can only be connected to the designated terminals.
(See section 3.3.5).
➢
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 section 3.3.1).
➢
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.
