This symbol means hazardous high voltage. It used to call your attention to items or operations
that could be dangerous to you or other persons operating this equipment.
Read these message and follow these instructions carefully.
This is the "Safety Alert Symbol" This symbol is used to call your attention to items or operations
that could be dangerous to you or other persons operating this equipment.
Read these messages and follow these instructions carefully.
CAUTION
WARNING Indicates a potentially hazardous situation which, if not avoided, can result in serious
injury or death.
CAUTION Indicates a potentially hazardous situation which, if not avoided, can result in minor to
moderate injury, or serious damage of product.
The matters described under may, if not avoided, lead to serious
results depending on the situation. Important matters are described in CAUTION (as
well as WARNING), so be sure to observe them.
NOTE Notes indicate an area or subject of special merit, emphasizing either the product's
capabilities or common errors in operation or maintenance.
HAZARDOUS HIGH VOLTAGE
Motor control equipment and electronic controllers are connected to hazardous line voltages.
When servicing drives and electronic controllers, there might be exposed components with cases
or protrusions at or above line potential. Extreme care should be taken to product against shock.
Stand on an insulating pad and make it a habit to use only one hand when checking components.
Always work with another person in case an emergency occurs. Disconnect power before
checking controllers or performing maintenance. Be sure equipment is properly grounded. Wear
safety glasses whenever working on an electronic controller or rotating electrical equipment.
N300-P INSTRUCTION MANUAL

PRECAUTION
CAUTION : These instructions should be read and clearly understood before working on
N300 series equipment.
NOTE : POLLUTION DEGREE2
The inverter must be used environment of the degree 2.
Typical constructions that reduce the possibility of conductive pollution are,
1) The use of an unventilated enclosure
2) The use of a filtered ventilated enclosure when the ventilation is fan forced that is, ventilation is
accomplished by one more blowers within the enclosure that provide a positive intake and
exhaust.
WARNING : This is equipment should be installed, adjusted and serviced by qualified electrical
maintenance personal familiar with the construction and operation of the equipment and the hazards
involved. Failure to observe this precaution could results in bodily injury.
WARNING :The user is responsible for ensuring that all driven machinery, drive train mechanism not
supplied by HYUNDAI and process line material are capable of safe operation at an applied frequency
of 150% of the maximum selected frequency range to the AC motor. Failure to do so can result in
destruction of equipment and injury to personnel should a single point failure occur.
WARNING : For protection, install an earth leakage breaker with a high frequency circuit capable of
large currents to avoid an unnecessary operation. The ground fault protection circuit is not designed
to protect personal injury.
WARNING : Hazard of electrical shock. Disconnect incoming power before working on this control.
WARNING : Separate motor overcurrent, overload and overheating protection is required to be
provided in accordance with the safety codes required by jurisdictional authorities.
CAUTION : Proper grounds, disconnecting devices and other safety devices and their
location are the responsibility of the user and are not provided by HYUNDAI.
CAUTION : Be sure to connect a motor thermal switch or overload devices to the N300
series controller to assure that inverter will shut down in the event of an overload or an
overheated motor.
CAUTION : Dangerous voltage exists until charge lamp is off.
CAUTION : Rotating shafts and above ground electrical potentials can be hazardous.
Therefore, it is strongly recommended that all electrical work conform to the National
Electrical Codes and local regulations. Only qualified personnel should perform installation,
alignment and maintenance. Factory recommended test procedures, included in the
instruction manual, should be followed. Always disconnect electrical power before working
on the unit.

1.4 Application Method for J61 Connector Pin according to Input
Power Grounding Condition
1.4.1 Usage of J61 Connector Pin and its application
(1) Usage of J61 Connector Pin
For N300 Inverter, a protection circuit is built-in case of lightning while being used, and it can be
also protected when J61 Connector Pin is connected.
However, the Inverter can be seriously affected according to its grounding condition(grounding
or non-grounding) of input transformer.
As a result, when Inverter products are yielded, J61 Connector Pin is separately provided (open
condition). Users should choose a set of J61 Connector Pin according to the second grounding
condition of input power as the below picture after deep consideration of your field situation.
(2) Comparison according to J61 Connector Pin Using or Non-using
a) Advantage of using J61 Connector Pin
Electronic products are often damaged by lightning or thunderbolt due to its sensitivity for the
weather changing. For N300 Inverter, a protection circuit is built-in to protect the inverter from
lightning or thunderbolt by using J61 Connector Pin.
Pre-caution
You should confirm the grounding condition of power source.
When using the second inverter(inverter power input), you should confirm if Y wiring is in neutral
ground system and if wiring is in upper ground system. If you use J61 Connector Pin in
non-grounding system, Inverter can be easily damaged by excessive noise from being
expressed through ZNR .
