Handing Precautions

• Always turn OFF the Controller before you mount or dismount a Unit or connect or disconnect cables.
• Provide separate conduits or ducts for the I/O lines to prevent noise from high-tension lines or power
lines.
• Prevent wire clippings, cutting chips or other materials from getting inside the Unit. They could cause
scorching, failure, and malfunction. Pay particular attention to this during installation and take mea-
sures such as covering with a cover.
• If the Unit was shipped from the factory with the dust protection label on top of the unit, be sure to
remove that label before switching ON the power. The label prevents heat dissipation and could
cause a malfunction.
