earthquakes will deteriorate.
Even if power is off, do not remove the front cover except for wiring or periodic
inspection. You may access the charged inverter circuits and get an electric shock.
Before starting wiring or inspection, check to make sure that the 3-digit LED inverter
monitor is off, wait for at least 10 minutes after the power supply has been switched
off, and check to make sure that there are no residual voltage using a tester or the
like.
This inverter must be earthed. Earthing must conform to the requirements of
national and local safety regulations and electrical codes. (JIS, NEC section 250,
IEC 536 class 1 and other applicable standards)
Any person who is involved in the wiring or inspection of this equipment should be
fully competent to do the work.
Always install the inverter before wiring. Otherwise, you may get an electric shock
or be injured.
Perform setting dial and key operations with dry hands to prevent an electric
shock.
Do not subject the cables to scratches, excessive stress, heavy loads or pinching.
Otherwise, you may get an electric shock.
Do not change the cooling fan while power is on. It is dangerous to change the
cooling fan while power is on.
When you have removed the front cover, do not touch the connector above the 3digit monitor LED display. Otherwise, you get an electrick shock.
A-1
2. Fire Prevention
CAUTION
Mount the inverter on an incombustible surface. Installing the inverter directly on or near
a combustible surface could lead to a fire.
If the inverter has become faulty, switch off the inverter power. A continuous flow of
large current could cause a fire.
Do not connect a resistor directly to the DC terminals +, -. This could cause a fire.
3. Injury Prevention
CAUTION
Apply only the voltage specified in the instruction manual to each terminal to
prevent damage, etc.
Always connect to the correct terminal to prevent damage, etc.
Always make sure that polarity is correct to prevent damage, etc.
While power is on or for some time after power-off, do not touch the inverter as it is
hot and you may get burnt.
4. Additional Instructions
Also note the following points to prevent an accidental failure, injury, electric shock,
etc.
(1) Transportation and installation
CAUTION
Environment
When carrying products, use correct lifting gear to prevent injury.
Do not stack the inverter boxes higher than the number recommended.
Ensure that installation position and material can withstand the weight of the
inverter. Install according to the information in the instruction manual.
Do not install or operate if the inverter is damaged or has parts missing.
When carrying the inverter, do not hold it by the front cover or setting dial; it may
fall off or fail.
Do not stand or rest heavy objects on the inverter.
Check the inverter mounting orientation is correct.
Prevent other conductive bodies as screws and metal fragments or other
flammable substance as oil from entering the inverter.
As the inverter is a precision instrument, do not drop or subject it to impact.
Use the inverter under the following environmental conditions: This could cause
the inverter damage.
Ambient
-10°C to +50°C (non-freezing)
Temperature
Ambient humidity 90%RH maximum (non-condensing)
Storage

*Temperatures applicable for a short time, e.g. in transit.
A-2
(2) Wiring
CAUTION
Do not fit capacitive equipment such as power factor correction capacitor, radio
noise filter (option FR-BIF(-H)) or surge suppressor to the output of the inverter.
The connection orientation of the output cables U, V, W to the motor will affect the
direction of rotation of the motor.
(3) Trial run
CAUTION
Check all parameters, and ensure that the machine will not be damaged by a
sudden start-up.
When the load GD2 is small (at the motor GD or smaller) for 400V from 1.5K to 3.7K, the
output current may vary when the output frequency is in the 20Hz to 30Hz range.
If this is a problem, set the Pr.72 "PWM frequency selection" to 6kHz or higher.
(When setting the PWM to a higher frequency, check for noise or leakage current
problem and take countermeasures against it.)
(4) Operation
WARNING
When you have chosen the retry function, stay away from the equipment as it will
restart suddenly after an alarm stop.
The [STOP] key is valid only when the appropriate function setting has been made.
Prepare an emergency stop switch separately.
Make sure that the start signal is off before resetting the inverter alarm. A failure to
do so may restart the motor suddenly.
The load used should be a three-phase induction motor only. Connection of any
other electrical equipment to the inverter output may damage the equipment.
Do not modify the equipment.
Do not perform parts removal which is not instructed in this manual. Doing so may
lead to fault or damage of the inverter.
A-3
CAUTION
The electronic thermal relay function does not guarantee protection of the motor
from overheating.
Do not use a magnetic contactor on the inverter input for frequent starting/stopping
of the inverter.
Use a noise filter to reduce the effect of electromagnetic interference. Otherwise
nearby electronic equipment may be affected.
Take measures to suppress harmonics. Otherwise power supply harmonics from
the inverter may heat/damage the power capacitor and generator.
When a 400V class motor is inverter-driven, please use an insulation-enhanced
motor or measures taken to suppress surge voltages. Surge voltages attributable to
the wiring constants may occur at the motor terminals, deteriorating the insulation of
the motor.
When parameter clear or all clear is performed, reset the required parameters
before starting operations. Each parameter returns to the factory setting.
The inverter can be easily set for high-speed operation. Before changing its
setting, fully examine the performances of the motor and machine.
In addition to the inverter's holding function, install a holding device to ensure safety.
Before running an inverter which had been stored for a long period, always
perform inspection and test operation.
(5) Emergency stop
CAUTION
Provide a safety backup such as an emergency brake which will prevent the
machine and equipment from hazardous conditions if the inverter fails.
When the breaker on the inverter primary side trips, check for the wiring fault (short
circuit), damage to internal parts of the inverter, etc. Identify the cause of the trip,
then remove the cause and power on the breaker.
When any protective function is activated, take the appropriate corrective action,
then reset the inverter, and resume operation.
(6) Maintenance, inspection and parts replacement
CAUTION
Do not carry out a megger (insulation resistance) test on the control circuit of the
inverter.
(7) Disposing of the inverter
CAUTION
Treat as industrial waste.
(8) General instructions

Control circuit
3.3.4
Power-off and magnetic contactor (MC)
(1) Inverter input side magnetic contactor (MC)
On the inverter's input side, it is recommended to provide an MC for the following
purposes. (Refer to page 3 for selection)
1) To release the inverter from the power supply when the inverter protective function
is activated or the drive becomes faulty (e.g. emergency stop operation)
2) To prevent any accident due to an automatic restart at restoration of power after an
inverter stop made by a power failure
3) To rest the inverter for an extended period of time
The control power supply for inverter is always running and consumes a little power.
When stopping the inverter for an extended period of time, powering off the inverter
will save power slightly.
4) To separate the inverter from the power supply to ensure safe maintenance and
inspection work
The inverter's input side MC is used for the above purpose, select class JEM1038AC3 for the inverter input side current when making an emergency stop during
normal operation.
REMARKS
The MC may be switched on/off to start/stop the inverter. However, since repeated inrush
currents at power on will shorten the life of the converter circuit (switching life is about 100,000
times), frequent starts and stops must be avoided. Turn on/off the inverter start controlling
terminals (STF, STR) to run/stop the inverter.

(2) Handling of output side magnetic contactor
In principle, do not provide a magnetic contactor between the inverter and motor and
switch it from off to on during operation. If it is switched on during inverter operation, a
large inrush current may flow, stopping the inverter due to overcurrent shut-off. When
an MC is provided for switching to the commercial power supply, for example, switch it
on/off after the inverter and motor have stopped.

Check that a proper power supply voltage is applied (operation panel
display is provided).
Check that the motor is connected properly.
Check that the jumper across + - P1 is connected.
Check that the start signal is input.
Check that both the forward and reverse rotation start signals are not
input simultaneously.
Check that the frequency setting signal is not zero.
Check that the AU signal is on when the frequency setting signal is 4 to
20mA.
Check that the output stop signal (MRS) or reset signal (RES) is not on.
(Assign signals MRS and RES using Pr. 60 to Pr. 63 (input terminal
function selection).)
Check that the sink or source jumper connector is fitted securely.
3) Check the parameter settings
Check that the reverse rotation prevention (Pr. 78) is not selected.
Check that the operation mode (Pr. 79) setting is correct.
Check that the bias and gain (C2 to C7) settings are correct.
Check that the starting frequency (Pr. 13) setting is not greater than the
running frequency.
Check that various operational functions (such as three-speed operation),
especially the maximum frequency (Pr. 1), are not zero.
4) Check the load
Check that the load is not too heavy.
Check that the shaft is not locked.
ERRORS AND PROTECTIVE FUNCTIONS
2) Check the input signals

Check that the SET ( WRITE ) was pressed.
Make sure that you are not attempting to set the parameter outside the setting
range.
Make sure that you are not attempting to set the parameter in the external
operation mode.
Check Pr. 77 "parameter write disable selection".
7.5.11 Motor produces annoying sound
Check the Pr. 70 "Soft-PWM setting" and Pr. 72 "PWM frequency selection"
settings.
Make sure that the deceleration time is not too short.

Precautions for maintenance and inspection
7.6 Precautions for maintenance and inspection
The inverter is a static unit mainly consisting of semiconductor devices. Daily
inspection must be performed to prevent any fault from occurring due to the adverse
effects of the operating environment, such as temperature, humidity, dust, dirt and
vibration, changes in the parts with time, service life, and other factors.
7.6.1
Precautions for maintenance and inspection
For some short time after the power is switched off, a high voltage remains in the
smoothing capacitor. When accessing the inverter for inspection, wait for at least 10
minutes after the power supply has been switched off, and then make sure that the
voltage across the main circuit terminals + - - of the inverter is not more than 30VDC
using a tester, etc.
7.6.2
Inspection item
(1) Daily inspection
•Basically, check for the following faults during operation.
1)Motor operation fault
2)Improper installation environment
3)Cooling system fault
4)Abnormal vibration, abnormal noise
5)Abnormal overheat, discoloration
• During operation, check the inverter input voltages using a tester.
(2) Cleaning
Always run the inverter in a clean status.
When cleaning the inverter, gently wipe dirty areas with a soft cloth immersed in
neutral detergent or ethanol.
CAUTION
Do not use solvent, such as acetone, benzene, toluene and alcohol, as they will
cause the inverter surface paint to peel off.
7.6.3
Periodic inspection
Check the areas inaccessible during operation and requiring periodic inspection.
Consult us for periodic inspection.
1)Cooling system fault. ........................... Clean the air filter, etc.
2)Tightening check and retightening ........ The screws and bolts may become loose
due to vibration, temperature changes, etc.
Check and tighten them.
Tighten them according to the specified
tightening torque.
3)Check the conductors and insulating materials for corrosion and damage.
4)Measure insulation resistance.
5)Check and replace the cooling fan, smoothing capacitor and relay.
52
Precautions for maintenance and inspection
7.6.4
Insulation resistance test using megger
1) Before performing the insulation resistance test on the external circuit, disconnect
the cables from all terminals of the inverter so that the test voltage is not applied to
the inverter.
2) For the continuity test of the control circuit, use a tester (high resistance range) and
do not use the megger or buzzer.
3) For the inverter, conduct the insulation resistance test on the main circuit only as
shown below and do not perform the test on the control circuit. (use the 500VDC

Precautions for maintenance and inspection
Checking the inverter and converter module
<Preparation>
(1) Disconnect the external power supply cables (L1, L2, L3) and motor cables (U, V, W).
(2) Prepare a tester. (Use 100Ω range).
<Checking method>
Change the polarity of the tester alternately at the inverter terminals L1, L2, L3, U, V,
W, P and N, and check for continuity.
CAUTION
•Before measurement, check that the smoothing capacitor is discharged.
•At the time of discontinuity, the measured value is almost ∞. When there is an
instantaneous continuity, due to the smoothing capacitor, the tester may not
indicate ∞. At the time of continuity, the measured value is several to several
ten's-of ohms depending on the module type, circuit tester type, etc. If all
measured values are almost the same, the modules are without fault.

Replacement of parts
The inverter consists of many electronic parts such as semiconductor devices.
The following parts may deteriorate with age because of their structures or physical
characteristics, leading to reduced performance or fault of the inverter. For preventive
maintenance, the parts must be replaced periodically.

Precautions for maintenance and inspection
(1) Cooling fan
The cooling fan is used to cool heat-generating parts such as the main circuit semiconductors.
The life of the cooling fan bearing is usually 10,000 to 35,000 hours. Hence, the cooling fan must
be replaced every 2 to 3 years if the inverter is run continuously. When unusual noise and/or
vibration is noticed during inspection, the cooling fan must be replaced immediately.

Removal
1) Remove the front cover and wiring cover. (Refer to page 1.)
2) Unplug the fan connectors.
The cooling fan is connected to
the cooling fan connector
beside the main circuit terminal
block of the inverter.
Unplug the connector and
separate the inverter from the
cooling fan.
3) Remove the cooling fan cover.
Disengage the fixing hooks
pointed by arrows to remove the
cooling fan cover.
4) Remove the cooling fan and
cooling fan cover.
The cooling fan is secured by
AIR FLOW
the fixing hooks.
Disengage the fixing hooks to
remove the cooling fan and
cooling fan cover.
Reinstallation
1) After confirming the orientation of
the fan, reinstall the fan so that the
arrow on the left of "AIR FLOW"
faces up.
CAUTION
Installing the fan in the opposite air
flow direction can cause the
inverter life to be shorter.
2) Reinstall the fan cover to the inverter.
Run the cable through the wiring groove to prevent it from being caught
between the chassis and cover.
3) Reconnect the cable to the connector. (Refer to "Removal" on the previous
page for the position of the connector.)
4) Reinstall the wiring cover.
58
Precautions for maintenance and inspection
(2) Smoothing capacitors
A large-capacity aluminum electrolytic capacitor is used for smoothing in the main
circuit DC section, and an aluminum electrolytic capacitor is used for stabilizing the
control power in the control circuit. Their characteristics are deteriorated by the
adverse effects of ripple currents, etc. The replacement intervals greatly vary with the
ambient temperature and operating conditions. When the inverter is operated in airconditioned, normal environment conditions, replace the capacitors about every 10
years.
When a certain period of time has elapsed, the capacitors will deteriorate more rapidly.
Check the capacitors at least every year (less than six months if the life will be expired
soon).
The appearance criteria for inspection are as follows:
1) Case: Check the side and bottom faces for expansion
2) Sealing plate: Check for remarkable warp and extreme crack.
3) Check for external crack, discoloration, fluid leakage, etc. Judge that the capacitor
has reached its life when the measured capacitance of the capacitor reduced below
85% of the rating.
(3) Relays
ERRORS AND PROTECTIVE FUNCTIONS
To prevent a contact fault, etc., relays must be replaced according to the cumulative
number of switching times (switching life).

Appendix 1 Instructions for compliance with the
European Directive
(The products conforming to the Low Voltage Directive carry the CE mark.)
(1) EMC Directive
1)Our view of transistorized inverters for the EMC Directive
A transistorized inverter is a component designed for installation in an enclosure and
for use with the other equipment to control the equipment/device. Therefore, we
understand that the EMC Directive does not apply directly to transistorized inverters.
For this reason, we do not place the CE mark on the transistorized inverters. (The
CE mark is placed on inverters in accordance with the Low Voltage Directive.) The
European power drive manufacturers' organization (CEMEP) also holds this point of
view.
2)Compliance
We understand that the transistorized inverters are not covered directly by the EMC
Directive. However, the EMC Directive applies to machines/equipment into which
transistorized inverters have been incorporated, and these machines and
equipment must carry the CE marks. Hence, we prepared the European Standardcompliant noise filters and the technical information "EMC Installation Guidelines"
(information number BCN-A21041-202) so that machines and equipment
incorporating transistorized inverters may conform to the EMC Directive more
easily.
3)Outline of installation method
Install an inverter using the following methods:
* Use the inverter with an European Standard-compliant noise filter.
* For wiring between the inverter and motor, use shielded cables or run them in a
metal piping and earth the cables on the inverter and motor sides with the shortest
possible distance.
* Insert a line noise filter and ferrite core into the power and control lines as required.
Full information including the European Standard-compliant noise filter
specifications are written in the technical information "EMC Installation Guidelines"
(BCN-A21041-202). Please contact your sales representative.
70
(2) Low Voltage Directive
1) Our view of transistorized inverters for the Low Voltage Directive
Transistorized inverters are covered by the Low Voltage Directive (Standard to
conform to: EN50178).
2) Compliance
We have self-confirmed our inverters as products compliant to the Low Voltage
Directive and place the CE mark on the inverters.
3) Outline of instructions
* For the 400V class inverter, the rated input voltage range is three phase 380V to
415V 50Hz/60Hz.
* Do not use an earth leakage circuit breaker as an electric shock protector without
connecting the equipment to the earth. Connect the equipment to the earth securely.
* Wire the earth terminal independently. (Do not connect two or more cables to one
terminal.)
* Use the cable sizes on page 8 under the following conditions.
·Ambient temperature: 40°C maximum
*
*
*
*
*
*
*
·Wire installation: On wall without ducts or conduits
If conditions are different from above, select appropriate wire according to
EN60204 ANNEX C TABLE 5.
Use the no-fuse breaker and magnetic contactor which conform to the EN or IEC
Standard.
Use the breaker of type B (breaker which can detect both AC and DC). If not,
provide double or enhanced insulation between the inverter and other equipment,
or put a transformer between the main power supply and inverter.
Use the inverter under the conditions of overvoltage category II and contamination
level 2 or higher specified in IEC664.
On the input and output of the inverter, use cables of the type and size set forth in
EN60204 Appendix C.
The operating capacity of the relay outputs (terminal symbols A, B, C) should be
30VDC, 0.3A.
Control circuit terminals on page 9 are safely isolated from the main circuit.

Appendix 2 Instructions for UL and cUL
(Standard to comply with: UL 508C, CSA C22.2 No.14)
1. Installation
The S500E is UL-listed as a product for use in an enclosure.
Design the enclosure so that the ambient temperature, humidity and ambience of
the inverter will satisfy the above specifications. (Refer to page 66)
Branch circuit protection
For installation in the United States, branch circuit protection must be provided in
accordance with the National Electrical Code and any applicable local codes.
For installation in Canada, branch circuit protection must be provided in accordance
with the Canada Electrical Code and any applicable provincial codes.
2. Wiring of the power supply and motor
For wiring the input (L1, L2, L3) and output (U, V, W) terminals of the inverter, use
the UL-listed copper wires (rated at 75°C) and round crimping terminals. Crimp the
crimping terminals with the crimping tool recommended by the terminal maker.
3. Short circuit ratings
Suitable For Use in A Circuit Capable Of Delivering Not More Than 5kA rms
Symmetrical Amperes.
72
4. Motor overload protection
These inverters provide solid state motor overload protection.
Set Pr. 9 using the following instructions,
(Pr. 9 "electronic thermal O/L relay").
<Setting>
• Set the rated current [A] of the motor in Pr. 9.
• Setting "0" in Pr. 9 disables electronic thermal relay function (motor protective function). (The protective function of the inverter is activated.)
• When using a Mitsubishi constant-torque motor, first set "1" in Pr. 71 "applied motor".
(This provides a 100% continuous torque characteristic in the low-speed range.)
Then, set the rated current of the motor in Pr. 9 "electronic thermal O/L relay".
CAUTION
•When two or more motors are connected to the inverter, they cannot be protected by
the electronic thermal relay function. Install an external thermal relay to each motor.
•When a difference between the inverter and motor capacities is large and the setting
becomes less than half amount of the inverter rated current, the protective
characteristics of the electronic thermal relay function will be deteriorated. In this case,
use an external thermal relay.
•A special motor cannot be protected by the electronic thermal relay function.
Use an external thermal relay.
