(4) Separate
the
power cable from the control signal cable, and input side of the power
cable from the output side. Separate them by at least 10cm. (30cm or more is
recommended.)
(5) Route the control cables inside the enclosure. If a control cable extends outside the
enclosure, use a shielded cable, and connect the earth shield to the control terminal
common and do not ground (earth) it. If required, use a ferrite core that is
commercially available. The ferrite core should be installed within 10cm from the
equipment.
Ferrite core
Shielded control wire
(Connect the shield earth
to the common (SD, SE, 5)
of the control terminal)
Cable between filter and
inverter should be as
short as possible.
EMC filter
Inverter
Metal panel for shielding
PLC, etc.
Separate for 30cm or more
(Minimum 10 cm)
Separate as far as
possible. Do not wire in
parallel, nor bind them.
Cross them if there is no
other choice.
Separate the input
cable and output cable
for more than 30cm.
Shielded cable or
metal conduit

Limit switch, sensor, etc.
Do not wire together in
parallel.

(6) Inserting the line noise filter FR-BLF or FR-BSF01, which is described in Chapter 4,
into the input or output side of the inverter improves the interference reduction effect.
