<1> The leakage current of this drive exceeds 3.5 mA. Therefore according to IEC61800-5-1 a protective earthing conductor with a cross section of at least 10 mm
be used. Smaller protective earthing conductors can be used if automatic power supply interruption in case of discontinuity of the protective earthing conductor is provided.
<2> Use a ring terminal end to connect the ground wire to the ground terminal.
NOTICE: Equipment Hazard. Be sure to connect the recommended fuses between each input terminal and the main circuit power supply (3-phase: L1, L2, L3, single-phase:
L1, L2). As the V1000 Series IP66 Type enclosure is very compact, fuses are required to prevent serious damage to the drive components as well as prevent
personal injury in the event that a short-circuit occurs.
Tightening Torque Values
Tighten the main circuit terminals using the torque values provided by the table below.
Tightening Torque (Nm)
Control Circuit
The control terminal board is equipped with screwless terminals. Always use wires within the specification listed below. For safe wiring it is
recommended to use solid wires or flexible wires with ferrules. The stripping length respectively ferrule length should be 8 mm.
Flexible with ferrule
Main and Control Circuit Wiring
Wiring the Main Circuit Input
Consider the following precautions for the main circuit input.
• Use fuses recommended in
• If using a ground fault circuit breaker, make sure that it can detect both DC and high frequency current.
• If using an input switch is used, make sure that the switch does not operate not more than once every 30 minutes.
• Use an AC reactor on the input side of the drive:
– to suppress harmonic current.
– to improve the power factor on the power supply side.
– when using an advancing capacitor switch.
– with a large capacity power supply transformer (over 600 kVA).
Wiring the Main Circuit Output
Consider the following precautions for the output circuit wiring.
• Do not connect any other load than a 3 phase motor to the drives output.
• Never connect a power source to the drives output.
• Never short or ground the output terminals.
