instruction is not observed.
CAUTION
This message indicates a situation which may lead to minor or moderate injury, or damage
of product.
HAZARDOUS HIGH VOLTAGE
Motor control equipment or electronic controllers are connected to hazardous line voltages.
When servicing drives and electronic controllers there might 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 personel
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 WATT Drive
Antriebstechnik GmbH 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.

responsibility of the user and are not provided by WATT Drive GmbH
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 personnel 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.
All of the above instructions, together with any other requirements, reccommendations,
and safety messages highlighted in this manual must be strictly complied with.
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 L2000 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 L2000 inverter must conform to the conditions stated below. If one of
the conditions mentioned is not satisfied then an appropriate L2000 AC reactor will have to be
installed.
•Voltage fluctuation +/-10% or less
•Voltage unbalance +/-3% or less
•Frequency variation +/-4% or less

Manual
Page 6 / 52
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, L2000 motor filters should be
installed. Directions for installing filters can be found in the L2000 installation manual.
•Seperate the mains circuit wiring from the wiring used for signals or process circuit. Please
refer to the L2000 installation manual.
D) Installation
•For L2000 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 choose the appropriate filter
using the table below:

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“.

Manual
Page 7 / 52
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.
•Take care 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 control 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 cabels 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).

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: 200~240V, 50/60Hz
Three phase: 380~460V, 50/60Hz
CAUTION Don´t connect AC power supply to the inverter output terminals U, V, and W.
Otherwise, there is a danger of injury and/or fire.

Safety precautions
Page 11 / 52
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.
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 personnel 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 personnel, 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.

Safety precautions
Page 12 / 52
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?
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 possibility 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 Before inspecting the unit wait at least five minutes before opening the inverter
.
CAUTION PROTECTION AGAINST NOISE INTERFERENCE FROM THE INVERTER
L2000 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 installed well apart from the inverter. It is also
effective to shield the whole inverter structure (refer to figure below, left part).

Addition of an 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.
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.

Inspection upon unpacking

Notes on technical specifications:
Note 1: Protective structure is based upon EN60529
Note 2: The applicable motor is a WATT DRIVE standard four-pole motor. When using
another motor, make sure that the rated motor current does not exceed the rated inverter
current.
Note 3: The output voltage will decrease if input voltage decreases.
Note 4a: The initial data setting values of 005N/011N are same as 007N/015N. So be sure
to set the correct values under b 12 and b 22 of 005N/007N for each motor first.
Note 4b: The initial data setting value of 030H is same as 040H. So be sure to set the
values under b 12 and b 22 of 030H for the motor first.
Note 5: Confirm with the motor manufacturer the motors maximum rpm when using a motor
running at frequencies higher than 50/60Hz
Note 6: Torque will be reduced when the base frequency exceeds 50Hz.
Note 7: In the range of 40 to 50°C reduce the carrier frequency to 2kHz and derate the
output current to 80% of the rated current, and remove the top cover.

A trip will occur when a running command is active at the time the
power supply is switched on. The power supply should not be
switched on simultaneously with the running command; instead
there should be a time delay of about 2 seconds from the time the
power supply is switched on until the running command is activated
(refer to time diagram). Also the power supply must not be switched
off while the running command is being active (motor is running).
