Precautions For Correct Use - Omron V680-HAM42-DRT User Manual

Always observe the following precautions to prevent operation failures, malfunctions, and adverse effects on
performance and equipment.
1. Installation and Storage Environment
Do not use or store the Product in the following locations.
• Locations exposed to corrosive gases, dust, metallic powder, or salts
• Locations not within the specified operating temperature range
• Locations subject to rapid changes in temperature or condensation
• Locations not within the specified operating humidity range
• Locations subject to direct vibration or shock outside the specified ranges
• Locations subject to spray of water, oil, or chemicals
2. Installation
• The Products communicate with Tags using the 13.56-MHz frequency band. Some transceivers,
motors, inverters, and switching power supplies generate noise that can affect communications with
the Tags and cause errors. If such devices are located near the Tags, always test operation in
advance to confirm whether the system will be affected.
• Observe the following precautions to minimize the effects of normal noise.
(1)Ground all metal objects in the vicinity of the Products to 100 Ω or less.
(2)Do not use the Products near high-voltage or high-current lines.
• Always bundle the cables connected to the power supply terminals and the ground terminal and
connect the enclosed ferrite core (ZCAT2032-0930 manufactured by TDK).
• Do not pull on the cables with excessive strength.
• The Products are not waterproof. Do not use them in an environment where mist is present.
• Do not expose the Products to chemicals that adversely affect the Product materials.
3. Host Communications
Always confirm that the Controller has been started before attempting to communicate with it from the
host. Also, when the Controller is started, unstable signals may be output from the host interface.
When starting operation, clear the reception buffers in the host or take other suitable countermeasures.
