INTRODUCTION
• There are no sudden variations in temperature (no condensation).
• The relative humidity is within the range stipulated in the specifications.
• No vibration or shock exceeding the values stipulated in the specifications is transmitted directly to
the body of the product.
• It is not subject to splashing water, oil, or chemical substances.
■ Mounting
• This product communicates with ID Tags using the 134 kHz frequency band. Some transceivers,
motors, monitoring equipment, and power supplies (power supply ICs) generate electrical waves
(noise) that interfere with communications with ID Tags. If you are using the product in the vicinity of
any of these devices, check the effect on communications in advance.
• In order to minimize the effects of noise, ground nearby metal bodies with a grounding resistance not
exceeding 100 ohms.
• When mounting Amplifier Units, tighten the screws with a torque no greater than 1.2 N·m.
• When mounting CIDRW Heads, tighten the screws with a torque no greater than 0.6 N·m.
• When multiple CIDRW Heads are mounted next to each other, communications performance could
be impaired by mutual interference. Read and follow the information in this manual on mutual inter-
ference when installing multiple heads.
Refer to page 111.
■ Power and Ground Cables
• Use the power supply voltage specified in this manual.
• Ensure correct polarity when connecting to the +/- power supply terminals.
• The ground terminals must be connected to a ground with a grounding resistance not exceeding 100
ohms.
• When using the CIDRW System in Europe, the connecting cable between the CIDRW and the DC
power supply must be 3 m or less.
■ Wiring Work
• Always turn the power off before starting wiring work or connecting/disconnecting cables.
• Do not run high-voltage lines and power lines though the same conduit.
• To prevent damage by static electricity, wear a wrist strap or equivalent, and take measures to pre-
vent charging, before touching terminal components or parts inside connectors.
■ Screw Locking Adhesive
• Screw locking adhesive (screw lock) may cause deterioration and cracking of resin parts; do not use
it for screws in resin parts or anywhere where resin washers are used.
■ Cleaning
• Use standard grade alcohol.
• Do not use organic solvents such as thinner or benzene.
