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
(2) Example of measures to comply with Low Voltage Directive
When incorporating the inverter into a machine and system, it is necessary to take the
following measures so that the inverter satisfies the Low Voltage Directive.
Paying attention to how to ground
• To ground shielded wires through a metal conduit.
• Connect grounding wires other than the shielded wires to the grounding terminals on the
inverter.
• However, do not connect two or more grounding wires to the grounding terminals (screws)
for the inverter main circuit.
• Refer to the table in [4. 1] to select a grounding wire size.
Installing protection device
• Install a fuse, an earth leakage circuit breaker (ELCB) or a molded-case circuit breaker
(MCCB) on the input side of the inverter. For details, refer to [3. 2. 3] [4. 2].
