Introduction
Always observe the following precautions to prevent operation failures, malfunctions, and adverse effects on
performance and equipment.
1. Installation Environment
Do not use the Products in the following locations.
• Locations exposed to direct sunlight
• 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 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 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.
• Do not use non-waterproof Products in an environment where mist is present.
• Do not expose the Products to chemicals that adversely affect the Product materials.
• When mounting the Products, tighten the screws to the following torques.
V680-HS51: 6 N⋅m
V680-HS52: 40 N⋅m
V680-HS63: 1.2 N⋅m
V680-HS65: 1.2 N⋅m
V680-H01-V2: 1.2 N⋅m
• Do not pull the Antenna connector over the power of 30 N.
The Antenna connector may be broken.
• Transmission will not be possible if the front and back panels are mistakenly reversed and the Unit is
mounted to a metallic surface.
V680-D1KP66MT
• The transmission distance will be reduced when the Unit is not mounted to a metallic surface.
V680-D1KP66MT
• If multiple Antennas are mounted near each other, communications performance may decrease due
to mutual interference. Refer to Installing Antennas on page 56 and check to make sure there is no
mutual interference.
• Depending on the operating environment, the case surface may become fogged, but basic perfor-
mance will not be affected.
