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.

2.1.1 Installation
1. Transportation
This inverter has plastic parts. So handle with care.
Do not over tighten the wall mounting fixings as the mountings may crack, causing is a risk of falling.
Do not install or operate the inverter if there appears to be damage or parts missing.
2. Surface for Mounting of Inverter
The temperature of the Inverter heatsink can become very high (the highest being about 150ºC). The
surface, which you are mounting the Inverter onto,must be made of a non-flammable material (i.e. steel)
due to the possible risk of fire. Attention should also be made to the air gap surrounding the Inverter.
Especially when there is a heat source such as a breaking resistor or a reactor.
3. Operating Environment - Ambient Temperature
The ambient temperature surrounding the Inverter should not exceed the allowable temperature range
(-10 to 40ºC). When using at 50ºC of ambient air temperature, the rated output current will be reduced.
(P.4-18)
The temperature should be measured in the air gap surrounding the Inverter, shown in the diagram
above. If the temperature exceeds the allowable temperature, the component life will become shortened
especially in the case of the Capacitors.
4.Operating Environment - Humidity
The humidity surrounding the Inverter should be within the limit of the allowable percentage range (20%
to 90%). Under no circumstances should the Inverter be in an environment where there is the possibility of
moisture entering the Inverter.
Also avoid having the Inverter mounted in a place that is exposed to the direct sunlight.
