9. Measures to satisfy standards 9-4
9
Using shielded power wires and shielded control wires
• Use shielded power wires, such as inverter input/output wires, and shielded control wires.
• Route the wires and wires so as to minimize their lengths.
• Keep a distance between the power cable and the control wire and between the input and
output wires of the power cable. Do not route them in parallel or bind them together.
Instead, if necessary, cross at right angle.
Installing inverter in steel cabinet
• Install the inverter in a sealed steel cabinet.
• Using wires as thick and short as possible, ground the metal plate and the control panel
securely with a distance kept between the grounding wire and the power wire.
Routing input and output wires apart
• Route the input and output wires apart as far as possible from each other.
Grounding of shielded wires
• To ground shielded wires through a metal conduit.
• To ground the shielded control wires by fixing the metal saddle of the body.
• Inserting a ferrite core in a shielded wire is even more effective in limiting the radiated noise.
Inserting zero-phase reactor and ferrite cores
• Insert a zero-phase reactor in the inverter output line.
• Insert ferrite cores in the grounding wires of the metal plate and cabinet.
(3) Measures for operation with external signals
To operate with external signals, take measures as shown in the figure below (e.g.: using a
potentiometer and Fwd/Rev terminals).
9. 1. 2 Compliance with Low Voltage Directive
The Low Voltage Directive provides for the safety of machines and systems.
(1) Low Voltage Directive Compliance of this inverter
Inverters are CE-marked in accordance with the requirement of Low Voltage Directive, and
can therefore be installed in machines or systems and exported without problem to European
countries.
• Applicable standard: IEC61800-5-1
• Pollution degree: 2
• Overvoltage category: 3
