(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
