Observe the following precautions to prevent failure to operate, malfunctions, or
undesirable effects on product performance.
1.Installation Site
Do not install this product in locations subjected to the following conditions:
• Ambient temperature outside the rating
• Rapid temperature fluctuations (causing condensation)
• Relative humidity outside the range of 35 to 85%
• Presence of corrosive or flammable gases

• Reflection of intense light (such as other laser beams or electric arc-welding
machines)
• Direct sunlight or near heaters
• Water, oil, or chemical fumes or spray
• Strong magnetic or electric field
2.Power Supply and Wiring
• When using a commercially available switching regulator, make sure that the FG
terminal is grounded.
• If surge currents are present in the power lines, connect surge absorbers that suit the
operating environment.
• Before turning ON the power after the product is connected, make sure that the power
supply voltage is correct, there are no incorrect connections (e.g. load short-circuit),
and the load current is appropriate. Incorrect wiring may result in breakdown of the
product.
• Before connecting/disconnecting devices, make sure that the Sensor/Controller is
turned OFF. The Sensor or Controller may break down if it is connected/disconnected
while the power is ON.
• Use the extension cable sold separately for extending the cable between the Sensor
and the Controller.
p.17
• Use only combinations of the Sensor and Controller specified in this manual.
• Before turning the Controller ON, connect the Sensor. If the Controller is turned ON
without the Sensor connected, the Controller’s screen will remain dark and messages
cannot be read.
