Warnings

WARNING
Disassembly and Dropping
Do not attempt to disassemble, repair, or modify the product in any way. Doing so may
result in malfunction or fire.
Installation
Always connect to a ground of 100 Ω or less when installing the product.
Ensure that installation and post-installation checks of the product are performed by per-
sonnel in charge who possess a thorough understanding of the machinery to be instal-
led.
Fail-safe Measures
Provide safety measures in external circuits to ensure safety in the system if an abnor-
mality occurs due to malfunction of the product or due to other external factors affecting
operation. Not doing so may result in serious accidents due to incorrect operation.
Emergency stop circuits, interlock circuit, limit circuits, and similar safety measures must
be provided in external control circuits.
Unintended behavior may occur when an error occurs in internal memory of the product.
As a countermeasure for such problems, external safety measures must be provided to
ensure safe operation of the system.
The use of an uninterruptible power supply (UPS) allows normal operation to continue
even if a momentary power failure occurs, possibly resulting in the reception of an erro-
neous signal from an external device affected by the momentary power failure. Take ex-
ternal fail-safe measures. Where necessary, monitor the power supply voltage on the
system for external devices and use it as an interlock condition.
Do not use the input functions of the touchscreen in applications that involve human life,
in applications that may result in serious injury, or for emergency stop switches.
