The wiring procedure for the FRN0.75C1S-2
types, perform wiring in accordance with their individual terminal arrangement. (Refer to page 2-3.)
Grounding terminals ( G)
Be sure to ground either of the two grounding terminals for safety and noise reduction. It is stipu-
lated by the Electric Facility Technical Standard that all metal frames of electrical equipment must
be grounded to avoid electric shock, fire and other disasters.

is given below as an example. For other inverter
Grounding terminals should be grounded as follows:
1) Connect the grounding terminal of the 200 V or 400 V series
of inverters to a ground electrode on which class D or C
grounding work has been completed, respectively, in compli-
ance with the Electric Facility Technical Standard.
2) Connect a thick grounding wire with a large surface area and
which meets the grounding resistance requirements listed in
Table 2.7. Keep the wiring length as short as possible.

Above requirements are for Japan. Ground the inverter
according to your national and local safety requirements.
1) Connect the three wires of the 3-phase motor to terminals U,
V, and W, aligning phases each other.
2) The wiring length between the inverter and motor should not
exceed 50 m. If the wiring length exceeds 50 m, it is recom-
mended that an output circuit filter (option) be inserted.
Do not use one multicore cable to connect several
inverters with motors.
