1.2. BeforeSupplyingPowertotheInverter/ Avant d’alimenter le variateur
The main circuit must be correctly wired. For single phase supply use input terminals (R/L1, T/L3) and for three
phase supply use input terminals (R/L1, S/L2, T/L3). Terminals U/T1, V/T2, W/T3 must only be used to connect
the motor. Connecting the input supply to any of the U/T1, V/T2 or W/T3 terminals will cause damage to the
inverter.
This product is sold subject to IEC 61800-3. In a domestic environment this product may cause radio interference in which case the user may need to apply corrective measures.
• Motor over temperature protection is not provided.
Always turn OFF the power supply before attempting inverter installation and wiring of the user terminals.
• Wiring must be performed by a qualied personnel / certied electrician.
• Make sure the inverter is properly grounded. (
230V 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.
Make sure the inverter model matches the parameters 13-00.
• Reduce the carrier frequency (parameter 11-01) If the cable from the inverter to the motor is greater than 80
ft (25m). A high-frequency current can be generated by stray capacitance between the cables and result in
an overcurrent trip of the inverter, an increase in leakage current, or an inaccurate current readout.
• Be sure to install all covers before turning on power. Do not remove any of the covers while power to the
inverter is on, otherwise electric shock may occur.
• Do not operate switches with wet hands, otherwise electric shock may result.
• Do not touch inverter terminals when energized even if inverter has stopped, otherwise electric shock may
Be sure to install all covers before turning on power. Do not remove any of the covers while power to the
inverter is on, otherwise electric shock may occur.
• Do not connect or disconnect the motor during operation. This will cause the inverter to trip and may cause
damage to the inverter.
• Operations may start suddenly if an alarm or fault is reset with a run command active. Conrm that no run
command is active upon resetting the alarm or fault, otherwise accidents may occur.
• Do not operate switches with wet hands, otherwise electric shock may result.
• It provides an independent external hardware emergency switch, which emergently shuts down the inverter
output in the case of danger.
• If automatic restart after power recovery (parameter 07-00) is enabled, the inverter will start automatically
after power is restored.
• Make sure it is safe to operate the inverter and motor before performing a rotational auto-tune.
• Do not touch inverter terminals when energized even if inverter has stopped, otherwise electric shock may
result.
• Do not check signals on circuit boards while the inverter is running.
• After the power is turned off, the cooling fan may continue to run for some time.
It is essential to verify the VDI100 inverter nameplate and make sure that the VDI100 inverter has the correct
rating so it can be used in your application with the proper sized AC motor.

3.11.1. Cooling Fan Supply Voltage Selection (400V class)
The inverter input voltage range of the VDI100 400V class models ranges from 380 to 480Vac. In these models
the cooling fan is directly powered from the power supply. Inverter models VDI100-6900 ... 71600 requires the
user to select the correct jumper position based on the inverter input voltage (“440V” is the default position for
these models). Please select the correct position according to the input voltage. If the voltage setting is too
low, the cooling fan will not provide adequate cooling for the inverter resulting in an over-heat error. If the input
voltage is greater than 460Vac, select the “460V” position.

3.12. Inverter Wiring
Warning
Wiring Precautions
• Do NOT remove any protective covers or attempt any wiring while input power is applied. Connect all
wiring before applying input power. When making wiring changes after power up, remove input power
and wait a minimum of ve minutes after power has been turned off before starting. Also conrm that the
charge lamp is off and that DC voltage between terminals B1/P or (+) and (-) does not exceed 25V, otherwise electric shock may result.
• Only authorized personnel should work on the equipment. (Take off metal jewelry such as watches and
rings and use insulated tools.), otherwise electric shock or injury may result.
