Precautions
WARNING
Always provide protective circuits in the network. Without protective
circuits, malfunctions may possibly result in accidents that cause serious
injury or significant property damage. Provide double or triple safety
measures in external control circuits, such as emergency stop circuits,
interlock circuits, or limit circuits, to ensure safety in the system if an
abnormality occurs due to malfunction of the product or another external
factor affecting the product's operation.
Design the system to ensure safety in the event of temporary
interruptions in communications due to interference with the
electromagnetic waves used for communications caused by the ambient
environment and application methods.
Do not use this product for real-time control.
Using the FA Wireless SS Terminal near a pacemaker or other medical
device may affect the operation of the medical device, possibly resulting
in serious injury. Never use the FA Wireless SS Terminal near
pacemakers or other medical devices.
CAUTION
Make sure that the direction and polarity (+/−) are correct when
connecting terminal blocks and connectors. Turning ON the power to I/O
circuits with the I/O cables connected in reverse, may result in a blown
output fuse.
Do not apply a voltage or connect a load to the outputs that exceeds the
maximum switching capacity.
Leave the dustproof label attached to the Unit when wiring. Be sure to
remove the label after the completion of wiring, however, to ensure
proper heat dissipation. Removing the label during wiring or leaving the
label attached after wiring may result in fire.
Do not allow pieces of metal, wire clippings, or fine metallic shavings or
filings from installation to enter the product. Doing so may occasionally
result in minor electric shock, fire, or malfunctions.
Do not attempt to disassemble, repair, or modify the product, or touch
the internal parts of the product. Doing so may occasionally result in
minor electric shock, fire, or malfunctions. In Japan, disassembly and
modification is also prohibited under Japan's Radio Law and may be
punishable by law.
