(2) Wiring

ꢁ

Do not connect a power factor correction capacitor, surge suppressor, or RFI filter to the output of the inverter.

The connection orientation of the output cables U, V, W to the motor will affect the direction of rotation of the

motor.

ꢁ

Incorrect terminal wiring could result in the equipment damage.

Reversing the polarity (+/-) of the terminals could damage the inverter.

Only authorized personnel familiar with LG inverter should perform wiring and inspections.

Always install the inverter before wiring. Otherwise, you may get an electric shock or have bodily injury.

(3) Trial run

ꢁ

Check all parameters prior to operation. Changing parameter values might be required depending on the load.

Always apply permissible range of voltage to the each terminal as indicated in this manual. Otherwise, it could

lead to inverter damage.

(4) Operation precautions

ꢁ

When the Auto restart function is selected, stay away from the equipment as a motor will restart suddenly after

a fault stop.

The Stop key on the keypad is valid only when the appropriate function setting has been made. Prepare an

emergency stop switch separately.

If a fault reset is made with the reference signal present, a sudden start will occur. Check that the reference

signal is turned off in advance. Otherwise an accident could occur.

ꢁ

Do not modify or alter anything inside the inverter.

Motor might not be protected by electronic thermal function of inverter.

Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter.

Use a noise filter to reduce the effect of electromagnetic interference. Otherwise nearby electronic equipment

may be affected.

ꢁ

In case of input voltage unbalance, install AC reactor. Power Factor capacitors and generators may become

overheated and damaged due to potential high frequency noise transmitted from inverter.

ꢁ

Before operating unit and prior to user programming, reset user parameters to default settings.

Inverter can easily be set to high-speed operations. Verify capability of motor or machinery prior to operating

unit.

ꢁ

Stopping torque is not produced when using the DC-Break function. Install separate equipment when stopping

torque is needed.

(5) Fault prevention precautions

ꢁ

Provide a safety backup such as an emergency brake which will prevent the machine and equipment from

hazardous conditions if the inverter fails.

(6) Maintenance, inspection and parts replacement

ꢁ

Do not conduct a megger (insulation resistance) test on the control circuit of the inverter.

Refer to Chapter 13 for periodic inspection (parts replacement).

(7) Disposal

ꢁ

Handle the inverter as an industrial waste when disposing of it.

(8) General instructions

ꢁ

Many of the diagrams and drawings in this instruction manual show the inverter without a circuit breaker, a

cover or partially open. Never run the inverter like this. Always place the cover with circuit breakers and follow

this instruction manual when operating the inverter.

ꢂ

When two or more inverters are installed or a ventilation fan is mounted in inverter panel, the inverters and ventilation

fan must be installed in proper positions with extreme care taken to keep the ambient temperature of the inverters

below the permissible value. If they are installed in improper positions, the ambient temperature of the inverters will rise

and ventilation effect will be reduced.

ꢂ

Install the inverter using screws or bolts to insure the inverter is firmly fastened.

When the input power is cut off due to instant power failure, the inverter outputs

Low voltage trip (LV) to hold the output.

When the power is restored, the inverter outputs the frequency before the low

voltage trip and the voltage is increased due to PI control.

t1 : If the rise in current is greater than the preset level in H23, the rise in voltage

will stop and the frequency is decreased.

t2 : If the opposite of t1 occurs, the increase in voltage starts again and the

decrease in frequency stops.

When the frequency and voltage are restored back to the nominal level,

acceleration will continue at the frequency before trip.

ꢀ Speed search is suitable operation when load inertia is great. It is highly recommended to restart

after stopping the motor when the load inertia is great.

Output Phase The inverter turns off its output when the one or more of the output (U, V, W) phase is

loss

open. The inverter detects the output current to check the phase loss of the output.

The inverter turns off its output if the DC voltage of the main circuit increases higher than

400 V when the motor decelerates. This fault can also occur due to a surge voltage

generated at the power supply system.

Over voltage

The inverter turns off its output if the DC voltage is below 180V because insufficient

torque or overheating of the motor can occur when the input voltage of the inverter drops.

The internal electronic thermal of the inverter determines the overheating of the motor. If

the motor is overloaded the inverter turns off the output. The inverter cannot protect the

motor when driving a motor having more than 4 poles or multi motors.

EMC INSTALLATION GUIDE

LG inverters are tested to meet Electromagnetic Compatibility (EMC) Directive 89/336/EEC and Low Voltage (LV)

Directive 73/23/EEC using a technical construction file. However, Conformity of the inverter with CE EMC requirements

does not guarantee an entire machine installation complies with CE EMC requirements. Many factors can influence total

machine installation compliance.

Essential Requirements for CE Compliance

Following conditions must be satisfied for LG inverters to meet the CE EMC requirements.

1. CE compatible LG inverter

2. Installing inverter in an EMC enclosure

3. Grounding enclosure and shielded parts of wire

4. Using shielded cable

5. Use it under industrial environment.

6. It is important that all lead lengths are kept as short as possible and that incoming mains and outgoing motor cables

are kept well separated.
