Caution Caution
Do not connect the product to a power supply outside the rated power supply voltage range
z
or to an AC power supply. Otherwise there is a risk of explosion or burnout.
Mistakenly wiring the product may cause the internal circuit to be damaged. Wire the input
z
and output circuits by referring to the connection examples in
RS-232
ply connection, so there is a risk of damage when the power supply connection is reversed.
Use extreme caution when connecting the power supply.
Avoid parallel wiring of the product's wires in the same conduit or duct with high voltage
z
lines or power lines (inverter power lines in particular) as this may cause malfunction or dam-
age due to the effect of induction noise.
If the wires are long and when there is a risk of being affected by power sources or solenoids,
z
independently wire the product as a general rule.
Avoid installing or using the product in the following locations as there is a risk of malfunc-
z
tion or damage.
- Near induction equipment or heat sources
- Locations with many vibrations or shocks
- Dusty and dirty locations
- In an atmosphere with hazardous gases such as sulfidizing gas
- Locations in direct contact with water, oils, or chemicals
