INTRODUCTION
■ 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.
■ 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
• Do not use organic solvents such as thinner or benzene.
■ Communications with the Host Device
Communicate with the host device only after confirming that the CIDRW Controller has started. Also,
unstable signals may occur at the host interface when the CIDRW Controller is started. When initializ-
ing operation, clear the reception buffer at the host device or take other suitable methods to clear
unwanted signals.
■ Startup Precaution
Never turn OFF the power supply while the CIDRW Controller is starting, including when power is
turned ON, when the mode is changed, or when the CIDRW Controller is being reset. Doing so may
damage the CIDRW Controller.
