General Precautions
Observe the following precautions when using the SYSDRIVE Inverters and peripheral
devices.
This manual may include illustrations of the product with protective covers removed in order
to describe the components of the product in detail. Make sure that these protective covers
are on the product before use.
Consult your OMRON representative when using the product after a long period of storage.
WARNING Do not touch the inside of the Inverter. Doing so may result in electrical shock.
WARNING Operation, maintenance, or inspection must be performed after turning OFF the
power
supply, confirming that the CHARGE indicator (or status indicators) are OFF ,
and after waiting for the time specified on the front cover . Not doing so may result in
electrical shock.
WARNING Do not damage, pull on, apply stress to, place heavy objects on, or pinch the cables.
Doing so may result in electrical shock.
WARNING Do not touch the rotating parts of the motor under operation. Doing so may result in
injury.
WARNING Do not modify the product. Doing so may result in injury or damage to the product.
Caution Do not store, install, or operate the product in the following places. Doing so may
result in electrical shock, fire or damage to the product.
SLocations subject to direct sunlight.
SLocations subject to temperatures or humidity outside the range specified in the
specifications.
SLocations
subject to condensation as the result of severe changes in temperature.
SLocations subject to corrosive or flammable gases.
SLocations subject to exposure to combustibles.
SLocations subject to dust (especially iron dust) or salts.
SLocations subject to exposure to water, oil, or chemicals.
SLocations subject to shock or vibration.
Caution Do not touch the Inverter radiator, regenerative resistor, or Servomotor while the
power
is being supplied or soon after the power is turned OFF . Doing so may result in
a skin burn due to the hot surface.
Caution Do not conduct a dielectric strength test on any part of the Inverter. Doing so may
result in damage to the product or malfunction.
Caution Take
appropriate and suf ficient countermeasures when installing systems in the fol -
lowing locations. Not doing so may result in equipment damage.
SLocations subject to static electricity or other forms of noise.

Transportation Precautions
Caution Do not hold by front cover or panel , instead, hold by the radiation fin (heat sink) while
transporting the product. Doing so may result in injury.
Caution Do not pull on the cables. Doing so may result in damage to the product or malfunc -
tion.
Caution Use
the eye-bolts only for transporting the Inverter . Using them for transporting the
machinery may result in injury or malfunction.
Installation Precautions
WARNING Provide an appropriate stopping device on the machine side to secure safety. (A
holding
brake is not a stopping device for securing safety .) Not doing so may result in
injury.
WARNING Provide an external emergency stopping device that allows an instantaneous stop of
operation and power interruption. Not doing so may result in injury.
Caution Be sure to install the product in the correct direction and provide specified clear-
ances between the Inverter and control panel or with other devices. Not doing so
may result in fire or malfunction.
Caution Do
not allow foreign objects to enter inside the product. Doing so may result in fire or
malfunction.
Caution Do not apply any strong impact. Doing so may result in damage to the product or
malfunction.
Wiring Precautions
WARNING Wiring must be performed only after confirming that the power supply has been
turned OFF. Not doing so may result in electrical shock.
WARNING Wiring must be performed by authorized personnel. Not doing so may result in
electrical shock or fire.
WARNING Be sure to confirm operation only after wiring the emergency stop circuit. Not doing
so may result in injury.
WARNING Always connect the ground terminals to a ground of 100 Ω or less for the 200-V AC
class, or 10 Ω or less for the 400-V AC class. Not connecting to a proper ground may
result in electrical shock.

Caution Install external breakers and take other safety measures against short-circuiting in
external wiring. Not doing so may result in fire.
Caution Confirm
that the rated input voltage of the Inverter is the same as the AC power sup -
ply voltage. An incorrect power supply may result in fire, injury, or malfunction.
Caution Connect
the Braking Resistor and Braking Resistor Unit as specified in the manual.
Not doing so may result in fire.
Caution Be
sure to wire correctly and securely . Not doing so may result in injury or damage to
the product.
Caution Be
sure to firmly tighten the screws on the terminal block. Not doing so may result in
fire, injury, or damage to the product.
Caution Do
not connect an AC power to the U, V , or W output. Doing so may result in damage
to the product or malfunction.
Operation and Adjustment Precautions
WARNING Turn ON the input power supply only after mounting the front cover , terminal covers,
bottom cover, Operator, and optional items. Not doing so may result in electrical
shock.
WARNING Do not remove the front cover , terminal covers, bottom cover , Operator , or optional
items while the power is being supplied. Not doing so may result in electrical shock or
damage to the product.
WARNING Do not operate the Operator or switches with wet hands. Doing so may result in
electrical shock.
WARNING Do not touch the inside of the Inverter. Doing so may result in electrical shock.
WARNING Do not come close to the machine when using the error retry function because the
machine may abruptly start when stopped by an alarm. Doing so may result in injury .
WARNING Do not come close to the machine immediately after resetting momentary power
interruption
to avoid an unexpected restart (if operation is set to be continued in the
processing selection function after momentary power interruption is reset). Doing so
may result in injury.
WARNING Provide a separate emergency stop switch because the ST OP Key on the Operator
is valid only when function settings are performed. Not doing so may result in injury .

WARNING Be sure confirm that the RUN signal is turned OFF before turning ON the power
supply, resetting the alarm, or switching the LOCAL/REMOTE selector. Doing so
while the RUN signal is turned ON may result in injury.
Caution Be sure to confirm permissible ranges of motors and machines before operation
because the Inverter speed can be easily changed from low to high. Not doing so
may result in damage to the product.
Caution Provide
a separate holding brake when necessary . Not doing so may result in injury .
Caution Do
not perform a signal check during operation. Doing so may result in injury or dam -
age to the product.
Caution Do not carelessly change settings. Doing so may result in injury or damage to the
product.
Maintenance and Inspection Precautions
WARNING Do not touch the Inverter terminals while the power is being supplied.
WARNING Maintenance or inspection must be performed only after turning OFF the power
supply, confirming that the CHARGE indicator (or status indicators) is turned
OFF ,
and after waiting for the time specified on the front cover . Not doing so may result in
electrical shock.
WARNING Maintenance, inspection, or parts replacement must be performed by authorized
personnel. Not doing so may result in electrical shock or injury.
WARNING Do not attempt to take the Unit apart or repair. Doing either of these may result in
electrical shock or injury.
Caution Carefully handle the Inverter because it uses semiconductor elements. Careless
handling may result in malfunction.
Caution Do not change wiring, disconnect connectors, the Operator, or optional items, or
replace
fans while power is being supplied. Doing so may result in injury , damage to
the product, or malfunction.
