Wire Connection and Optional Devices
7.5.13 Inverter Earth Terminal (G)
・Make sure that the inverter and motor are
grounded for use.
・Otherwise, you run the risk of electric
shock.
・In accordance with the electric installation
engineering standards, connect
200V-class model to the earth electrode
completing class-D ground work
(equivalent to the third class grounding:
100Ω or less grounding resistance) and
400V-class model to the earth electrode
completing class-C ground work
(equivalent to the special third class
grounding: 10Ω or less grounding
resistance).
7.5.14 Enable the Internal EMC Filter
・We want to enable the internal EMC filter.
・We want to comply with European Directive.
・Use grounding wires whose thickness is
not less than that of the applicable wires
and make them short as much as
possible.
・When more than one inverters are used,
connect them that the grounding route
(condition) should not be shared wires or
loops.
Otherwise, the inverter or peripheral
control devices may malfunction.
・To enable the EMC filter, move the short bar or
terminal.
・For locations to be shorted, see the main circuit
wiring diagram.
