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.

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)
