i.1 Using the Product Safely
12 YASKAWA SIEPYEULA5001C LA500 Technical Manual
i.1 Using the Product Safely
These instructions contain the information necessary to use the product correctly. Read and understand the safety
information and precautions before you start to use the product.
◆Explanation of Signal Words
Read and understand this manual before you install, operate, or do maintenance on the drive. Install the drive as
specified by this manual and local codes.
The symbols in this section identify safety messages in this manual. If you do not obey these safety messages, the
hazards can cause serious injury, death, or damage to the products and related equipment and systems. These
identifier words categorize and emphasize important safety precautions in these instructions.
DANGER
This signal word identifies a hazard that will cause serious injury or death if you do not prevent
it.
WARNING
This signal word identifies a hazard that can cause death or serious injuries if you do not
prevent it.
CAUTION
This signal word identifies a hazard that can cause minor or moderate injuries if you do not
prevent it.
NOTICE
This signal word identifies a property damage message that is not related to personal injury.
◆Section Safety
•Some figures in the instructions include options and drives without covers or safety shields to more clearly
show the inside of the drive. Replace covers and shields before operation. Use options and drives only as
specified by the instructions.
•The figures in this manual are examples only. All figures do not apply to all products included in this manual.
•The manufacturer can change the products, specifications, and content of the instructions without notice to
make the product and/or the instructions better.
•If you damage or lose these instructions, contact a representative or the nearest sales office of the manufacturer.
You can find the contact information on the rear cover of the manual, and tell them the document number to
order new copies. You can also download the manual from the manufacturer’s website.
DANGER
Do not ignore the safety messages in this manual.
If you ignore the safety messages in this manual, it will cause serious injury or death. The manufacturer is not
responsible for injuries or damage to equipment.
Electrical Shock Hazard
Do not examine, connect, or disconnect wiring on an energized drive. Before servicing,
disconnect all power to the equipment and wait for the time specified on the warning label at a
minimum. The internal capacitor stays charged after the drive is de-energized. The charge
indicator LED extinguishes when the DC bus voltage decreases below 50 Vdc. When all
indicators are OFF, measure for dangerous voltages to make sure that the drive is safe.
If you do work on the drive when it is energized, it will cause serious injury or death from electrical shock.

i.1 Using the Product Safely
YASKAWA SIEPYEULA5001C LA500 Technical Manual 13
WARNING
Crush Hazard
Test the system to make sure that the drive operates safely after you wire the drive and set
parameters.
If you do not test the system, it can cause damage to equipment or serious injury or death.
Sudden Movement Hazard
Before you do a test run, make sure that the setting values for virtual input and output function
parameters are correct. Virtual input and output functions can have different default settings
and operation than wired input and output functions.
Incorrect function settings can cause serious injury or death.
Remove all personnel and objects from the area around the drive, motor, and machine and
attach covers, couplings, shaft keys, and machine loads before you energize the drive.
If personnel are too close or if there are missing parts, it can cause serious injury or death.
Examine the I/O signals and internal sequence with the engineer who made the DriveWorksEZ
program before you operate the drive.
If you do not know how the drive will operate, it can cause serious injury or death. When you use DriveWorksEZ
to make custom programming, the drive I/O terminal functions change from factory settings and the drive will
not operate as written in this manual.
Electrical Shock Hazard
Do not modify the drive body or drive circuitry.
Modifications to drive body and circuitry can cause serious injury or death, will cause damage to the drive, and
will void the warranty. Yaskawa is not responsible for modifications of the product made by the user.
Only let approved personnel install, wire, maintain, examine, replace parts, and repair the drive.
If personnel are not approved, it can cause serious injury or death.
Do not remove covers or touch circuit boards while the drive is energized.
If you touch the internal components of an energized drive, it can cause serious injury or death.
After the drive blows a fuse or trips an RCM/RCD, do not immediately energize the drive or
operate peripheral devices. Wait for the time specified on the warning label at a minimum and
make sure that all indicators are OFF. Then check the wiring and peripheral device ratings to
find the cause of the problem. If you do not know the cause of the problem, contact Yaskawa
before you energize the drive or peripheral devices.
If you do not fix the problem before you operate the drive or peripheral devices, it can cause serious injury or
death.
Damage to Equipment
Do not apply incorrect voltage to the main circuit of the drive. Operate the drive in the specified
range of the input voltage on the drive nameplate.
Voltages that are higher than the permitted nameplate tolerance can cause damage to the drive.
Fire Hazard
Install sufficient branch circuit short circuit protection as specified by applicable codes and this
manual. The drive is suited for circuits that supply not more than 31,000 RMS symmetrical
amperes, 240 Vac maximum (200 V Class), 480 Vac maximum (400 V Class).
Incorrect branch circuit short circuit protection can cause serious injury or death.
CAUTION
Crush Hazard
Tighten terminal cover screws and hold the case safely when you move the drive.
If the drive or covers fall, it can cause moderate injury.

i.1 Using the Product Safely
14 YASKAWA SIEPYEULA5001C LA500 Technical Manual
NOTICE
Use an inverter-duty motor or vector-duty motor with reinforced insulation and windings
applicable for use with an AC drive.
If the motor does not have the correct insulation, it can cause a short circuit or ground fault from insulation
deterioration.
Damage to Equipment
When you touch the drive and circuit boards, make sure that you observe correct electrostatic
discharge (ESD) procedures.
If you do not follow procedures, it can cause ESD damage to the drive circuitry.
Do not do a withstand voltage test or use a megohmmeter or megger insulation tester on the
drive.
These tests can cause damage to the drive.
Do not operate a drive or connected equipment that has damaged or missing parts.
You can cause damage to the drive and connected equipment.
Do not use steam or other disinfectants to fumigate wood for packaging the drive. Use
alternative methods, for example heat treatment, before you package the components.
Gas from wood packaging fumigated with halogen disinfectants, for example fluorine, chlorine, bromine, iodine
or DOP gas (phthalic acid ester), can cause damage to the drive.

Electric Shock Hazard. Disconnect the device from main power supply and wait 5 minutes before you touch the drive or parts of it.
DANGER
Electrical Shock Hazard
Do not examine, connect, or disconnect wiring on an energized drive. Before servicing, disconnect all power to
the equipment and wait for the time specified on the warning label at a minimum. The internal capacitor stays
charged after the drive is de-energized. The charge indicator LED extinguishes when the DC bus voltage
decreases below 50 Vdc. When all indicators are OFF, measure for dangerous voltages to make sure that the
drive is safe.
If you do work on the drive when it is energized, it will cause serious injury or death from electrical shock.
Hot surfaces. Risk of burn.
CAUTION
Burn Hazard
Do not touch a hot drive heatsink. De-energize the drive, wait for a minimum of 15 minutes, then make sure that
the heatsink is cool before you replace the cooling fans.
If you touch a hot drive heatsink, it can burn you.
