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.

WARNING WARNING

Indicates a potentially hazardous situation which, if not avoided, can result in

serious injury or death.

CAUTION 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 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 protru-

sions 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 controllers or rotating electrical equipment.

CAUTION

PRECAUTION

: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.

:The user is responsible for ensuring that all driven machinery, drive train

mechanism not supplied by Hitachi, Ltd., 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.

: For protection, install an earth leakage breaker with a high frequency circuit

capable of large currents to avoid an unnecessary operation. The ground faults protection circuit is not

designed to protect personal injury.

: HAZARD OF ELECTRICAL SHOCK. DISCONNECT INCOMING POWER

BEFORE WORKING ON THIS CONTROL.

:SEPARATE MOTOR OVERCURRENT, OVERLOAD AND OVERHEATING

PROTECTION IS REQUIRED TO BE PROVIDED IN ACCORDANCE WITH THE SAFETY CODES

REQUIRED BY JURISDICTIONAL AUTHORITIES.

:These instructions should be read and clearly understood before working on

L300P series equipment.

:Proper grounds, disconnecting devices and other safety devices and their location

are the responsibility of the user and are not provided by Hitachi, Ltd.

: Be sure to connect a motor thermal switch or overload devices to the L300P

series controller to assure that inverter will shut down in the event of an overload or an overheated

motor.

:DANGEROUS VOLTAGE EXISTS UNTIL CHARGE LAMP IS OFF.

: 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. Installation, alignment and maintenance should be performed only by qualified

personnel. Factory recommended test procedures, included in the instruction manual, should be

followed. Always disconnect electrical power before working on the unit.

NOTE : POLLUTION DEGREE 2

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 un-ventilated enclosure

2) The use of a filtered ventilated enclosure when the ventilation is fan forced that is, ventilation is

accomplished by one or more blowers within the enclosure that provide a positive intake and

exhaust.

Cautions for EMC (Electromagnetic Compatibility)

You are required to safety the EMC directive (89/336/EEC) when using the L300P inverter in a

European country. To safety the EMC directive and to comply with standard, follows the checklist

below.

: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 L300P 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 L300P 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 3 kHz 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 - +40 ºC.

b. Humidity: 20 to 90% RH (non-condensing)

c. Vibration: 5.9 m/sec2(0.6 G) 10 – 55Hz. (L300P-110-300LF/110-300HF)

2.94 m/sec2(0.3 G) 10 – 55Hz. (L300P-370-750LF/370-1320HF)

d. Location: 1000meters or less altitude, indoors (no corrosive gas or dust)

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 that 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.
