Hyundai N300-P User manual

SAFETY
For the Best Results with N300 Series inverter, read this manual and all of the warning sign
attached to the inverter carefully before installing and operating it, and follow the instructions exactly.
Keep this manual handy for your quick reference.
Definitions and Symbols
A safety instruction (message) is given with a hazard alert symbol and a signal word,
WARNING or CAUTION. Each signal word has the following meaning throughout this manual.
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.

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.

Cautions for EMC (Electromagnetic Compatibility)
To safety the EMC directive and to comply with standard, follows the checklist below.
WARNING
This equipment should be installed, adjusted, and serviced by qualified personal familiar with
construction and operation of the equipment and the hazards involved. Failure to observe
this precaution could result in bodily injury.
1. The power supply to N300-P inverter must meet these specifications
a. Voltage fluctuation 10% or less.
b. Voltage imbalance 3% or less.
c. Frequency variation 4% or less.
d. Voltage distortion THD = 10% or less.
2. Installation measure :
a. Use a filter designed for N300-P inverter
3. Wiring
a. Shielded wire (screened cable) is required for motor wiring, and the length must be less
than 20 meters.
b. The carrier frequency setting must be less than 3kHz to satisfy EMC requirements.
c. Separate the main circuit from the signal/process circuit wiring.
d. In case of remote operating with connector cable, the inverter does not conform to EMC.
4. Environmental conditions - when using a filter, follow these guidelines:
a. Ambient air temperature : -10 - +50 .
b. Humidity : 20 to 90% RH(non-condensing)
2
c. Vibration : 5.9 m/sec (0.6 G) 10 - 55Hz ( N300- 055 - 300LFP / 055 - 300HFP)
2.94 2
m/sec (0.6 G) 10 - 55Hz ( N300- 370 - 750LFP / 370 - 1600HFP)
d. Location : 1000meters of less altitude, indoors (no corrosive gas or dust)
N300-P INSTRUCTION MANUAL

Conformity to the Low Voltage Directive (LVD)
The protective enclosure must conform to the Low Voltage Directive.
The inverter can conform to the LVD by mounting into a cabinet or by adding covers as follows.
1. Cabinet and Cover
The inverter must be installed into a cabinet which has the protection degree of Type IP2X.
In addition the top surfaces of cabinet are easily accessible shall meet at least the requirements of
the protective Type IP4X, or which is constructed to prevent small objects from entering inverter.
