(2) Use shielded wires for the motor power cable and
route it as short as possible. Firmly clamp the wire
shield to the flange to ground it. Further, connect the
wire shield electrically to the grounding terminal of
motor. (See Figure 10.2.)
(3) Use shielded wires for the control signals of the
drive to input to/output from the control terminals.
Firmly clamp the control wire shields to the EMC
grounding flange (in the same way as the power
wires).

(4) If noise from the drive exceeds the permissible level,
enclose the drive and its peripherals within a metal
control board as shown in Figure 10.3.

10.4 Harmonic Component Regulation in the EU
10.4.1 General comments
When you use general-purpose industrial drives in the
EU, the harmonics emitted from the drive to power lines
are strictly regulated as stated below.
If a drive whose rated input is 1 kW or less is connected
to public low-voltage power supply, it is regulated by the
regulation related to harmonics emission from drives to
power lines (with the exception of industrial low-voltage
power lines). Refer to Figure 10.4 below for details.

* Drive types marked with
√
in the table above are
compliant with the EN61000-3-2 (+A14), so they
may be connected to commercial power lines
unconditionally.
Conditions apply when connecting models marked
with “—“. If you want to connect them to commer-
cial power lines, you need to obtain permission from
the local electric power supplier. In general, you will
need to provide the supplier with the harmonics
current data of the drive. To obtain the data, contact
us.
Note 1) When supplying 3-phase 230 Vac power
stepped down from a 3-phase 460 Vac power line using
a transformer, the level of harmonic flow from the
460 Vac line will be regulated.
