This section explains troubleshooting
fault trips and other common faults.
If problems are not solved, please
contact your vendor or LSIS.
This section provides information
on how to maintain the inverters on
a regular basis for different time
periods.
When there is a problem in the
inverter, please check the
input/output module. This is the
basic method to check the
hardware.
This section covers check points
when there is a problem in the
inverter.
Then check the parameter settings
using basic operations and the trip
records.

Safety Information
Read and follow all safety instructions in this manual precisely to avoid unsafe operating conditions,
property damage, personal injury, or death.
Safety symbols in this manual
Danger
Indicates an imminently hazardous situation which, if not avoided, will result in severe injury or
death.
Warning
Indicates a potentially hazardous situation which, if not avoided, could result in injury or death.
Caution
Indicates a potentially hazardous situation that, if not avoided, could result in minor injury
or property damage.
Safety information
Danger
Do not open the cover of the equipment while it is on or operating. Likewise, do not operate
the inverter while the cover is open. Exposure of high voltage terminals or charging are to the
external environment may cause an electric shock. Do not remove any covers or touch the
internal circuit boards (PCBs) or electrical contacts on the product when the power is on or
during operation. Doing so may cause serious injury, death or serious property damage.
Do not open the cover of the equipment even when the power supply to the inverter has been
turned off unless it is necessary for maintenance or regular inspection. Opening the cover
may lead to an electric shock even when the power supply is off.
The equipment may hold charge long after the power supply has been turned off. Use a multi-
meter to make sure that there is no voltage before working on the inverter, motor, or motor
cable.

Warning
This equipment must be grounded for safe and proper operation.
Do not supply power to a faulty inverter. If you find that the inverter is faulty, disconnect the
power supply and have the Inverter repaired.
The Inverter becomes hot during operation. Avoid touching the Inverter until it has cooled
down to avoid burns.
Do not allow external objects, such as screws, metal chips, debris, water, or oil to get inside
the Inverter. Allowing external substances inside the Inverter may cause the Inverter to
malfunction or ignite fire.
Do not operate the Inverter with wet hands. Doing so may cause electric shock.
Caution
Do not modify the interior structure/components of the Inverter. Doing so will void the
warranty.
The Inverter is designed for 3-phase motor operation. Do not use the Inverter to operate 3-
phase motor.
Do not place heavy objects on top of electric cables. Doing so may damage the cable and
cause an electric shock.

Does the environment meet the inverters operating conditions?
Does the power source match the inverter’s rated input?
Is the rated output of the inverter sufficient to supply the equipment?
Power Terminal
Wiring
Is the circuit breaker installed on the input side of the inverter?
Is the circuit breaker correctly rated?
Are the power source cables correctly connected to the R/S/T terminals
of the inverter?
(Caution: Connecting the power source to the U/V/W terminals may
damage the inverter)
Are the motor output cables connected in the correct phase rotation
(U/V/W)?
(Caution: Motors will rotate in reverse direction if three phase cables are
not wired in the correct rotation)
Are the cables used to connect power terminals correctly rated?
Is the inverter grounded properly?
Are the power terminal screws and the ground terminal screws tightened
to their specific torques?
Are the overload protection circuits installed correctly on the motors (if
multiple motors are running using one inverter)?
Is the inverter separated from the power source by a magnetic contactor
(if a braking resistor is in use)?
Are advanced-phase capacitors, surge protection and electromagnetic
interference filters installed correctly?
(These devices MUST NOT be installed on the output side of the
inverter)
