 Always install the inverter before wiring. Otherwise, electric shock or bodily injury can
occur.
 Wire insulation recommended for main power circuits.(Refer to Appendix A)
(3) Trial run
 Check all parameters during operation. Parameter values might require adjustment
depending on the application.
 Always apply voltage within the permissible range of each terminal as indicated in
this manual. Otherwise, inverter damage may result.
 Current hunting can be occurred in the low speed territory during testing. It occurs
where the capacity is above 110kW with no-load and the axis is not connected. The
currnet hunting have a gap according to the motor characteristic. It will be
disappeared when the load is connected and it is not the indication of abnormal
condition. If the hunting is occurred seriously, please stop the testing and operates
with the load.
(4) Operation precautions
 When the Auto restart function is selected, the inverter will restart after a fault has
occurred.
 The Stop key on the keypad can only be used to stop the inverter when keypad
control is enabled. Install a separate emergency stop switch if necessary.
 If a fault reset is made with the run command and /or reference signal present, a
sudden start will occur. Check that the run command and /or reference signal is
turned off in advance of resetting any faults. Otherwise an accident could occur.
 Do not modify the inverter.
 Depending on the motor specifications and user ETH overload settings, the motor
may not be protected by electronic thermal function of inverter.
 The operation of the inverter is intended to be controlled by either keypad command
or control input signals. Do not use a magnetic contactor or any other device that
routinely disconnects the inverter and reconnects the inverter to the input supply
power for the purpose of starting and stopping the motor.
 A noise filter may be installed to reduce the effect of electromagnetic interference.
Otherwise nearby electronic equipment may be affected.
 In cases with input voltage unbalances, install an AC input reactor.
 Power Factor capacitors and generators may become overheated and damaged due
to harmonics created by the inverter.
 Use an insulation-rectified motor or take measures to suppress the micro surge
voltage when driving 460V class motor with inverter. A micro surge voltage
attributable to wiring constant is generated at motor terminals, and may deteriorate
insulation and damage motor.

(9) Protective requirements
The accessible connections and parts listed below are of protective class 0, it means that the
protection of these circuits relies only upon basic insulation and becomes hazardous in the
event of a failure of the basic insulation. Therefore, devices connected to these circuits must
provide electrical-shock protection as if the device was connected to supply mains voltage. In
addition, during installation these parts must be considered, in relation with electrical-shock,
as supply mains voltage circuits.
