Safety Precautions
Data recovery
Backup data and keep the data up-to-date periodically to prepare for data loss.
When using an intranet environment through a global address, connecting to an unauthor-
ized terminal such as a SCADA, HMI or to an unauthorized server may result in network se-
curity issues such as spoofing and tampering.
You must take sufficient measures such as restricting access to the terminal, using a termi-
nal equipped with a secure function, and locking the installation area by yourself.
When constructing an intranet, communication failure may occur due to cable disconnection
or the influence of unauthorized network equipment.
Take adequate measures, such as restricting physical access to network devices, by means
such as locking the installation area.
When using a device equipped with the SD Memory Card function, there is a security risk
that a third party may acquire, alter, or replace the files and data in the removable media by
removing the removable media or unmounting the removable media.
Please take sufficient measures, such as restricting physical access to the Controller or tak-
ing appropriate management measures for removable media, by means of locking the instal-
lation area, entrance management, etc., by yourself.
Caution
If connecting a commercially available braking resistor or regenerative braking unit, this may
result in a moderate burn due to the heat generated in the braking resistor or regenerative
braking unit.
In case of a braking resistor, install a thermal relay that monitors the temperature of the re-
sistor. Configure a sequence that enables the inverter power to turn OFF when unusual over
heating is detected in the braking resistor or regenerative braking unit.
The inverter has high voltage parts inside which, if short-circuited, might cause damage to
itself or other property.
Place covers on the openings or take other precautions to make sure that no metal objects
such as cutting bits or lead wire scraps go inside when installing and wiring.
Install a stop motion device to ensure safety. Not doing so might result in a minor injury.
(A holding brake is not a stop motion device designed to ensure safety.)
Be sure to confirm safety before conducting maintenance, inspection or parts replacement.
A breakdown of the built-in braking transistor could result in braking resistor heating or dam-
age to the inverter's internal units. Shut off the main power of the inverter using Braking tran-
sistor broken signal (DBAL).
A breakdown of the built-in braking transistor or misconnection of the braking resistor could
result in braking resistor heating or damage to the inverter's internal units.
If the inverter does not start up or continue being undervoltage (LU) after the main power of
the inverter is turned ON, shut off the main power of the inverter.
When installing the product, use only the specified screws.
Not doing so may result in fire or accidents.
Do not install or operate an inverter with damaged external or internal components.
Doing so may result in injury, fire or accidents.
