Safety Instructions

Wiring
Caution
A professional installer should have done the wiring and checking.
Do wiring after installing the inverter body.
Do not connect phase-leading capacitors, surge filter, radio noise filter to the output
of inverter.
Output terminals (terminals named U, V, W respectively) should be connected in a
proper phase sequence.
Make sure that there is not any short circuit terminal, wrong wiring. It may cause
spurious operation or failure.
Refrain from using a cable other than the cable shielded when you connect control
circuit wiring.
Adopt the shielded wire only when wiring the control circuit. It may cause the failure
of inverter in its operation. Use the twisted pair shield wire for the ground terminal of
the inverter.
Warning
To prevent an electric shock, be sure to check if MCCB and MC are
switched OFF before wiring
Otherwise, it may cause an electric shock.
Adjustment before starting trial operation
Do not supply the excessive range of voltage displayed in the user manual to the
each terminal. It may cause damage to the inverter.
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 current hunting has a gap according to the motor characteristic. It will be dis-
appeared when the load is connected and it is not the indication of abnormal condi-
tion.
If the hunting is occurred seriously, please stop the testing and operates with the
load.
Be sure to check relevant parameters for the application before starting trial opera-
tion.
How to Use
Be sure not to approach the machine when retry function is selected. The machine
may start working suddenly.
Stop key on the keypad should be set to be in use. For safety, additional emergency
stop circuit should be required.
Inverter restarts if alarm condition is cleared while FX/RX signal is on. Therefore, be
sure to operate the alarm reset switch after checking if FX / RX signal is off.
Never modify the inverter for inappropriate use.
When a magnetic contactor is installed on the power source, do not frequently start
or stop using this magnetic contactor. It may cause the failure of inverter.
