There are troubleshooting fault trips &

other faults in these pages.

If problems are not resolved, please

contact your vendor or LSIS.

There are the regular inspection

lists in these pages.

When the problem of inverter occur,

please check the input/output

module that is basic hardware

check method.

When the problem of inverter occur,

you can check the basic checklist

before you think it is failure in these

pages.

check the set-up of parameter using

basic operations first and then

check the trip record.

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 hazardoussituation which, if not avoided, willresult in severe injury or death.

Warning

Indicates a potentiallyhazardous situation which, if not avoided, couldresult in injuryordeath

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 area to the external

environment may result in an electric shock. Do not remove anycovers or touch the internal circuit

boards (PCBs) or electricalcontacts on the product when the power is on or during operation.

Doing so may result in 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

turnedoff unlessit is necessaryfor maintenance or regular inspection. Opening the cover may

result in an electric shock even when thepower supply isoff.

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 professionally repaired.

The inverter becomes hot during operation.Avoid touching the inverter until it has cooled to avoid

burns.

Do not allowforeignobjects, such as screws, metal chips, debris, water, or oil to get inside the

inverter.Allowing foreign objects inside the inverter maycause the inverter to malfunction or result in

a fire.

Do not operate the inverter with wet hands. Doing so mayresult in electric shock.

Caution

Do not modify the interior workings 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 a single

phase motor.

Do not place heavy objects on top of electric cables. Doing so may damage the cable and result in

an electric shock.

Is the installation location appropriate?

Does the environment meet the inverter’s operating conditions?

Does the power source match the inverter’s rated input?

Is the inverter’s rated output sufficient to supply the equipment?

PowerTerminal

Wiring

Is a 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 in the power terminal connections correctly rated?

Is the invertergrounded correctly?

Are the power terminal screws and the ground terminal screws

tightened to their specified torques?

Are the overload protection circuits installed correctly on the motors (if

multiple motors are run using one inverter)?

Is the inverterseparated 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.)

Control

TerminalWiring

Are STP(shielded twisted pair) cables used for control terminal wiring?

Is the shielding of the STP wiring properlygrounded?

If 3-wire operation is required, are the multi-function input terminals

defined prior to the installation of the control wiring connections?

Are the control cables properly wired?

Are the control terminal screws tightened to their specified torques?

Is the total cable length of all control wiring < 165ft (50m)?

Is the total length of safety wiring < 100ft (30m)?

Miscellaneous

Are optional cards connected correctly?

Is there any debris left inside the inverter?

Are any cables contacting adjacent terminals, creating a potentialshort

circuit risk?

Are the control terminal connections separated from the power

terminal connections?

Have the capacitors been replaced if they have been in use for > 2

years?

Has afuse been installed for the power source?

Are the connections to the motor separated from other connections?
