(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 during 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 an alarm 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 an alarm 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.
