The wiring procedure for the CUB5A-1
†
is given below as an example. For other inverter types,
perform wiring in accordance with their individual terminal arrangement. (Refer to page 2-3.)
c Grounding terminals ( G)
Be sure to ground either of the two grounding terminals for safety and noise reduction. All metal
frames of electrical equipment must be grounded to avoid electric shock, fire and other disasters.
Figure 2.4 Grounding Terminal
Wiring
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.
d Inverter output terminals, U, V, and W
1) Connect the three wires of the 3-phase motor to terminals U, V,
and W.
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.

minal Wiring
Do not use one multicore cable to connect several in-
verters with motors.
