Introduction
• Install the Unit properly as shown in this manual. Not doing so may result in a failure
of the Unit.
• Do not install the Sensor Communications Unit in locations subject to the following
conditions:
• Locations subject to direct sunlight
• Locations subject to temperatures or humidity outside the range specified in the
specifications
• Locations subject to condensation as the result of severe changes in temperature
• Locations subject to corrosive or flammable gases
• Locations subject to dust (especially iron dust) or salts
• Locations subject to exposure to water, acid, oil, or chemicals
• Locations subject to shock or vibration
• Be sure to observe the voltage specifications when performing wiring between com-

failure of the Unit.
• Wire the Unit properly as indicated in this manual.
• Use the correct wiring parts to perform wiring.
• Take appropriate and sufficient countermeasures when using the Unit in the following
locations:
• Locations subject to static electricity or other forms of noise
• Locations subject to strong electromagnetic fields
• Locations subject to possible exposure to radioactivity

• Do not drop the Digital Sensor Communications Unit or expose it to any excessive
vibration or shock. Doing so may result in damage to the Digital Sensor Communica-
tions Unit or malfunction.
• The CompoNet Communications Unit provides power to the connected Sensors.
Therefore, the operation of the Sensors may become unstable if there are abnormali-
ties in the power supply, such as a drop in the power supply voltage at startup. If Sen-
sor operation is unstable, check the voltage specifications and wiring, and then cycle
the power supply.
