(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.
Installing in cabinet
• Install the inverter in a cabinet and ground the inverter enclosure.
• When doing maintenance, be extremely careful not to put your fingers into the inverter
through a wiring hole and touch a charged part, which may occur depending on the model
of the inverter used.
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 [10. 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 [9. 2. 3] [10. 2. 2].
