HAZARDOUS HIGH VOLTAGE
Motor control equipment or electronic controllers are connected to hazardous line
voltages. When servicing drives and electronic controllers there migh exist exposed
components with cases or protrusions at or above line potential. Extreme care should
be taken to protect against shock.
For these reasons, the following safety guidelines should be observed:
Stand on an insulating pad and make it a habit to use only one hand when checking
components. Disconnect power before checking controllers or performing
maintenance. Be sure that equipment is grounded properly. Wear safety glasses
whenever working on an electronic controller or rotating electrical equipment.
WARNING This equipment should be installed, adjusted and serviced only by qualified electrical
maintenace personnel familiar with the construction and operation of the equipment
and the hazards involved. Failure to observe this precaution could result in bodily
injury.
WARNING The user is responsible 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.
WARNING HAZARD OF ELECTRICAL SHOCK. DISCONNECT INCOMING POWER
BEFORE WORKING ON THIS CONTROL.
WARNING SEPARATE MOTOR OVERLOAD AND OVERCURRENT PROTECTION
DEVICES ARE REQUIRED TO BE PROVIDED IN ACCORDANCE WITH THE
SAFETY CODES REQUIRED BY JURISDICTIONAL AUTHORITIES.
CAUTION These instructions should be read and clearly understood before working on L100IP
series equipment.
CAUTION Proper grounds, disconnecting devices (e.g. fuses) and other safety devices and their
location are the responsibility of the user and are not provided by Hitachi, Ltd.
CAUTION DANGEROUS VOLTAGE EXISTS UNTIL THE POWER LIGHT ON THE
DIGITAL OPERATOR IS OFF.

CAUTION Rotating shafts and electrical potentials above ground level can be hazardous.
Therefore it is strongly recommended that all electrical work conform to the national
electrical codes and local regulations. Installation, maintenance and alignment should
be performed by qualified personnell only.
Factory recommended test procedures included in this instruction manual should be
followed. Always disconnect electrical power before working on the unit.
WARNING a) Any motor used must be of suitable rating.
b) Motors may have hazardous moving parts so that suitable protection must be
provided in order to avoid injury.
CAUTION Alarm connections may have hazardous live voltages even when the inverter is
disconnected. In case of removing the front cover for maintenance or inspection,
confirm that incoming power for alarm connections is surely disconnected.
CAUTION Main terminals or other hazardous terminals for any interconnection (terminals for
connecting the motor, contact breaker, filter etc.) must be inaccessible in end
installation.
CAUTION If the unit is used in a manner not specified by the manufacturer the protection
provided by the unit may be impaired..
All of the above instructions, together with any other requirements, reccommendations,
and safety messages highlighted in this manual must be strictly complied with for continued LVD
compliance.

NOTES ON EMC (ELECTRO MAGNETICAL COMPATIBILITY)
WARNING This equipment should be installed, adjusted and serviced by qualified personnel
familiar with construction and operation of the equipment and the hazards
involved. Failure to observe this precaution could result in bodily injury.
When using L100IP series inverters in EU countries, the EMC directive 89/336/EEC must be observed. To
satisfy the EMC directive and to comply with the standard, the following provisions should be obeyed:
A) Environmental conditions for the inverter:
•Ambient temperature: -10°C to 40°C.
•Relative Humidity: 20% to 90% (no dew condensation)
•Vibrations: max. 5,9m/s2(0.6 g) at 10–55Hz.
•Location: 1000 meter or less altitude, indoors (no corrosive gas or dust).
B) The power supply to the L100IP inverter must conform to the conditions stated below. If one of the
conditions mentioned is not satisfied then an appropriate L100IP AC reactor will have to be installed.
•Voltage fluctuation +/-10% or less
•Voltage unbalance +/-3% or less
•Frequency variation +/-4% or less
C) Wiring
•Shielded wiring (screened cable) is required for motor wiring, and total length has to be kept to less
than 50m. When using motor cables longer than 50m L100IP motor filters should be installed.
Directions for installing filters can be found in the L100IP installation manual.
•The carrier frequency setting must be less than 5 kHz to satisfy EMC requirements.
•Separate the mains circuit wiring from the wiring used for signals or process circuit. Please refer to
the L100IP installation manual.
D) Installation
•For L100IP series inverters, the filters described hereafter have to be used and the installation notes
have to be observed.
If installed according to the following directions, the frequency inverters comply with the following standards:
Emmissions: EN 61800-3 (EN 55011 group 1, class B)
Immunity: EN 61800-3, industrial environments
For the best possible damping of interference, special line filters have been developed which guarantee
you easy assembly and installation along with the necessary electrical reliability. However, effective
EMC is only ensured if the suitable filter is selected for the particular drive and installed in accordance
with these EMC recommendations. Please order the appropriate filter when ordering L100IP inverter.
Note: All filters are designed for 50Hz/60Hz +/-5%.
The amount of line-conducted interference also increases as motor cable length increases. Adherence to the
interference limits for line-conducted interference is guaranteed on following way:
•If maximum motor cable length is 10 m at maximum elementary frequency:
Class „B“.
•If maximum motor cable length is 20 m at elementary frequency 5 kHz:
Class „B“.
•If maximum motor cable length is 50 m at maximum elementary frequency:
Class „A“.
Observe the following provisions for an electromagnetically compatible setup of your drive system:
1. As user you must ensure that the HF impedance between frequency inverter, filter and ground is as small
as possible.
•See to it that the connections are metallic and have the largest possible areas (zink-plated mounting
plates)
2. Conductor loops act like antennas, especially when they encompass large areas. Consequently:
•Avoid unnecessary conductor loops

•Avoid parallel arrangement of „clean“ and interference-prone conductors
3. Lay the motor cable and all analog and digital contol lines shielded.
•You should allow the effective shield area of these lines to remain as large as possible; i.e., do not
move the shield further away than absolutely necessary.
•With compact systems, if for example the frequency inverter is communicating with the steering unit,
in the same control cabinet connected at the same PE-potential, the screen of control lines should be
put on, on both sides with PE. With branch systems, if for example the communicating steering unit is
not in the same control cabinet and there is a distance between the systems, we recommend to put on
the screen of control lines only on the side of the frequency inverter. If it is possible, direct in the cable
entry section of the steering unit. The screen of motor cables always must be put on, on both sides with
PE.
•The large area contact between shield and PE-potential you can realise with a metal PG screw
connection or a metallic mounting clip.
•Use only copper mesh cable (CY) with 85% coverage
•The shielding should not be interrupted at any point in the cable. If the use of reactors, contactors,
terminals or safety switches in the motor output is necessary, the unshielded section should be kept as
small as possible.
•Some motors have a rubber gasket between terminal box and motor housing. Very often, the terminal
boxes, and particularly the threads for the metal PG screw connections, are painted. Make sure there is
always a good metallic connection between the shielding of the motor cable, the metal PG screw
connection, the terminal box and the motor housing, and carefully remove this paint if necessary.
4. Very frequently, interference is coupled in through installation cables. This influence you can minimize:
•Lay interfering cables separately, a minimum of 0.25 m from cables susceptible to interference.
•A particularly critical point is laying cables parallel over larger distances. If two cables intersect, the
interference is smallest if they intersect at an angle of 90°. Cables susceptible to interference should
therefore only intersect motor cables, intermediate circuit cables, or the wiring of a rheostat at right
angles and never be laid parallel to them over larger distances.
5. The distance between an interference source and an interference sink (interference-threatened device)
essentially determines the effects of the emitted interference on the interference sink.
•You should use only interference-free devices and maintain a minimum distance of 0.25 m from the
drive.
6. Safety measures
•Ensure that the protective conductor terminal (PE) of the filter is properly connected with the protective
conductor terminal of the frequency inverter. An HF ground connection via metal contact between the
housings of the filter and the frequency inverter, or solely via cable shield, is not permitted as
protective conductor connection. The filter must be solidly and permanently connected with the ground
potential so as to preclude the danger of electric shock upon touching the filter if a fault occurs. You
can achieve this by connecting it with a grounding conductor of at least 10 mm² or connecting a second
grounding conductor, connected with a separate grounding terminal, parallel to the protective
conductor (the cross section of each single protective conductor terminal must be designed for the
required nominal load).

Chapter 1 – Safety precautions
Installation
The following safety precautions are to be observed when installing the frequency inverter:
CAUTION Be sure to install the inverter on flame resistant material such as metal. Otherwise,
there is a danger of fire.
CAUTION Be shure not to place anything inflammable in the vicinity. Otherwise, there is a
danger of fire.
CAUTION Be sure not to let foreign matter (such as cut wire refuse, spatter from welding, iron
refuse, wires, dust etc.) enter the inverter. Otherwise, there is a danger of fire.
CAUTION Install the inverter in a room which is not exposed to direct sunlight and is well
ventilated. Avoid environments which tend to be high in temperature, high in
humidity or which have dew condensation, as well as places with dust, corrosive
gas, explosive or inflammable gas, grinding-fluid mist, salt damage etc. Otherwise,
there is a danger of fire.
CAUTION The wall surface on which the inverter is mounted must be of a nonflammable
material, such as a steel plate.
Wiring
WARNING The inverter has to be grounded properly. Otherwise, there is a danger of fire.
WARNING Wiring work must only be carried out when the power supply is off. Otherwise,
there is a danger of electric shock and/or fire.
WARNING Before carrying out the wiring work, the inverter has to be mounted properly.
Otherwise, there is a danger of electric shock or injury.
CAUTION Make shure that the input voltage is as follows (please also refer to chapter 11):
Single/three phase: 200~240V, 50/60Hz (models up to 2,2kW)
Three phase: 380~460V, 50/60Hz
CAUTION Don´t connect AC power supply to the inverter output terminals U, V, and W or fan
supply terminals F, F. Otherwise, there is a danger of injury and/or fire.

CAUTION Remarks for using earth leakage circuit breakers in the mains supply:
Frequency inverters with CE-filters (RFI-filter) and screened motor cables have a
higher leakage current against earth. Especially in the moment of switching this can
cause unintentional triggering of earth leakage circuit breakers. Because of the rectifier

Chapter 1 – Safety precautions
1-2
on the input side of the inverter there is the possibility to stall the switch-off function
through amounts of DC current. For these reasons, the following items should be
observed:
Only pulse current sensitive earth leakage circuit breakers which have a short term
delay and a higher trigger current (500mA) should be used. Other components should
be secured with separate earth leakage circuit breakers. Earth leakage circuit breakers
in front of an inverter´s rectifier are not an absolute protection against direct touching.
CAUTION Each phase of the power supply has to be provided with a fuse. Otherwise, there is a
danger of fire.
Control and operation
WARNING Be sure to turn on the input power supply only after closing the front case. While
being energized, don´t open the front case. Otherwise, there is a danger of electric
shock.
WARNING Never operate the switches with wet hands. Otherwise, there is a danger of electric
shock.
WARNING If the retry mode is selected, the inverter may suddenly restart during a stop which
was caused by a trip. In such a case, be sure not to approach the machine. Provisions
have to be taken that the driven motor or machine does not endanger personnell even
in the case of a sudden restart. Otherwise, there is a danger of injury.
WARNING Even if the power supply is cut off for a short period of time, the inverter may restart
operation after the power supply has recovered if the operation command is given. If
this may incur danger to personnell, provisions have to be made in order to prevent a
restart after power recovery. Otherwise, there is a danger of injury.
WARNING The STOP key is effective only if the corresponding parameters have been set.
Otherwise, there is a danger of injury.
WARNING If a reset is carried out following a trip condition the motor will restart if the
operation command has been given. Be sure to acknowledge this trip condition with
a reset only after confirming that no operation command is active. Otherwise, there
is a danger of injury.
WARNING When the power to the inverter is turned on while the operation command is active
the motor starts immediately. So before turning power supply on be sure to confirm
that no operation command is active.
WARNING If the inverter has been configured for the stop command not to be given using the
STOP key, pressing the STOP key does not stop the motor. In this case a separate
emergency stop switch is necessary.
CAUTION Operate the motor and machine connected to the inverter only within the
manufacturer´s speed specifications. Otherwise, there is a danger of injury.
CAUTION If a motor is to be operated at a frequency higher than the standard setting value of
50 or 60Hz, be sure to check the allowable speed of the motor and the machine
with each manufacturer, and operate them only after getting their consent.
CAUTION Check the following during and after the test run. Otherwise, there is a danger of
machine breakage:
Was the short cut bar between terminals +1 and + removed by mistake?
Was the running direction of the motor correct?
Was the inverter tripped during acceleration or deceleration?
Were the indications of the rpm and the frequency meter correct?
Were there any abnormal motor vibrations or noise?

Chapter 1 – Safety precautions
1-3
Maintenance and inspection
WARNING Before carrying out maintenance and inspection wait for at least five minutes after
having turned off the input power supply. Otherwise, there is a danger of electric
shock.
WARNING When removing connectors (e.g. from fans and printed circuit boards) never pull the
attached wires. Otherwise, there is a danger of fire due to wire breakage and/or
injury.
Others
CAUTION Withstand voltage tests and insulation resistance tests (megger tests) are executed
before the units are shipped, so that there is no need to conduct these tests before
operation.
CAUTION Do not attach or remove wiring or connectors when power is applied. Also, do not
check signals (e.g. using a multimeter) during operation.
CAUTION Never stop motor operation by switching off the electromagnetic contactors on the
primary or secondary side of the inverter.

When there has been an instantaneous power failure, and if an operation instruction
has been given, then the inverter may restart operation after the power failure has
ended. If there is a possibibility that such an occurrence may harm humans, then install
an electromagnetic contactor on the primary (power supply) side of the inverter, so
that the circuit does not allow automatic restarting after the power supply has
recoverd. If the optional remote operator is used and the retry function has been
selected, this will also cause automatic restarting when an operation instruction has
been input, so please be careful.
CAUTION Do not insert leading power factor capacitors or surge absorbers between the output
terminals of the inverter and the motor.

CAUTION PROTECTION AGAINST NOISE INTERFERENCE FROM THE INVERTER
L100IP series inverters use many semiconductor switching elements such as
transistors and IGBTs. For this reason, a radio set or measuring instrument located
near the inverter is susceptible to noise interference. To protect the instruments from
erreneous operation due to noise interference produced by the inverter, they should be

Added EMI filter on the input side of the inverter also reduces the effect of noise from
commercial power lines on external devices (refer to figure above).
CAUTION EFFECTS OF DISTRIBUTER LINES ON INVERTERS
In the cases mentioned below involving a general purpose inverter, a large peak
current flows on the power supply side, sometimes destroying the converter module:
A) The unbalance factor of the power supply is 3% or higher.
B) The power supply capacity is set at least ten times greater than the inverter
capacity (i.e. 500kVA or more)
C) When abrupt power supply changes are to be expected. Some examples:
1) Several inverters are interconnected using a short bus to the same power
supply.
2) A thyristor converter and an inverter are interconnected using a short bus.
3) An installed power factor compensating device is connected or disconnected.
In the cases mentioned above we recommend installing an AC reactor of 3% voltage
drop at rated current with respect to the supply voltage on the power supply side.
CAUTION When an EEPROM error occurs (trip E 08) all parameter values have to be checked
for correctness (especially the RS input).
CAUTION When the intelligent digital inputs FW or RV are configured as normally closed
contact (standard setting is normally open), then the inverter starts automatically. Do
not configure these inputs as normally closed inputs unless absolutely necessary.
CAUTION Factory setting of the carrier frequency is different for diferent types of the inverter.
This setting is at the same time also highest allowable carrier frequency without
derating output power. See bottom of the terminal cover for reference.
GENERAL NOTICE
In all the illustrations and figures in this manual, covers and safety devices are
occasionally omitted in order to better describe the details. When the inverter is
operated make shure that all the covers and safety devices are placed in their correct
positions.

CAUTION Remarks for using earth leakage circuit breakers in the mains supply
Frequency inverters with CE-filters (RFI-filter) and screened motor cables have a
higher leakage current against earth. Especially in the moment of switching this can
cause unintentional triggering of earth leakage circuit breakers. Because of the rectifier
on the input side of the inverter there is the possibility to stall the switch-off function
through amounts of DC current. For these reasons, the following items should be
observed:
Only pulse current sensitive earth leakage circuit breakers which have a short term
delay and a higher trigger current (500mA) should be used. Other components should
be secured with separate earth leakage circuit breakers. Earth leakage circuit breakers
in front of an inverter´s rectifier are not an absolute protection against direct touching.
CAUTION Each phase of the power supply has to be provided with a fuse. Otherwise, there is a
danger of fire.
CAUTION As for motor leads, earth leakage breakers, and electromagnetic contactors, be sure to
use the ones that have the correct rating. Otherwise, there is a danger of fire.
CAUTION Make sure that the mains supply leads are reliably fixed.
Wiring the power supply and motor
In order to connect cables to the power supply and other terminals the terminal cover has to be opened. For
this, first of all the four corresponding screw has to be loosened. The location of the terminals is depicted in
the figure below:
CAUTION Don’t disconnect wires attached to F terminals (fan power supply), otherwise
inverter may overheat. In case the wires are exchanged, the fan doesn’t work. This
terminals cannot be used for the power supply for external device.
When connecting cables, the following details have to be considered:
1) Power supply cables must only be connected to the terminals L1, L2, L3 or L, N.
2) Refer the page 5-5 for wiring equipment and options.

3) If more than one motor is to be driven by a single inverter, thermal relays have to be provided for each
motor.

4) The leads from the power supply must be connected to the mains circuit terminals as follows:
Connect single phase power supply (50/60Hz) to terminals L1, N.
Connect three phase power supply (50/60Hz) to terminals L1, L2, L3.
Wiring the control terminals
