Do not install under the following environments.
• Locations subject to temperatures exceeding the specified temperature and humidity ranges
• Locations with high salt or iron content
• Locations under direct vibration or shock
• Outdoor, or locations with an altitude of higher than 2,000 m
Do not operate a damaged unit.
The TD-260T is classified as an open-type (built-in) device and must be installed inside a control panel.
If the top cover and the panel are dirty, wipe them with a soft cloth lightly dampened with a solution of a neutral detergent and
water, and then wipe them again with a damp, well wrung-out cloth. DO NOT use a chemically treated dust cloth, paint thinner,
or other flammable solvents. Using any of them could damage the coating of the product.
