2. PRECAUTIONS
POWER SUPPLY
Verify that the supply voltage variation is within the rating. Also, the voltage variation at the end terminal of the
transmission route, since voltage drop occurs depending on the diameter or the length of the transmission cable.
If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the
power supply is connected to an actual ground.
Do not use during the initial transient time after the power supply is switched on. Further, if the system is in BUSY
condition, the signal transmission is not carried out.
Make sure to use an isolation transformer for the DC power supply. If an auto-transformer (single winding transformer)
is used, this product or the power supply may get damaged.
In case a surge is generated in the used power supply, connect a surge absorber to the supply and absorb the surge.
In case the connected computer is turned off first, note that the output hold function of S-LINK output unit may not work.
WIRING
Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can
cause malfunction due to induction.
Make sure to carry out the installation and wiring in the power supply off condition.
In order to reduce noise, make the wiring as short as possible.
Always use the specified transmission cable.
Take care that wrong wiring will damage the product.
ENVIRONMENT
In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity of this product,
connect the frame ground (F.G.) terminal of the equipment to an actual ground.
This product does not have a dust-proof or water-proof construction. Do not use it in a place having excessive
vapor, dust etc.
Take care that the product does not come in direct contact with water, chemicals or organic solvents, such as
thinner, etc. Further, do not use it in an environment having corrosive gas.
Do not use the product in places where the ambient temperature or the humidity exceeds the specifications.
TERMINAL
Do not tighten the screws with a torque exceeding the specifications.
OTHERS
S-LINK is not compatible with S-LINK V.
Please refer to the S-LINK Design Manual and the S-LINK Construction Manual for details of the complete
S-LINK system.
Design the protection or safety circuits against system trouble external to the S-LINK system.
