Warnings
• The surface on which the switch is placed should be adequately secured to prevent it from becoming
unstable and/or falling over.
• Ensure the power source circuits are properly grounded.
• Observe and follow service markings. Do not service any product except as explained in your system
documentation. Opening or removing covers marked with a triangular symbol with a lighting bolt may
cause electrical shock. These components are to be serviced by trained service technicians only.
• Ensure the power cable, extension cable, and/or plug is not damaged.
• Ensure the product is not exposed to water.
• Ensure the device is not exposed to radiators and/or heat sources.
• Do not push foreign objects into the device, as it may cause a fire or electric shock.
• Use the device only with approved equipment.
• Allow the product to cool before removing covers or touching internal equipment.
• Ensure the switch does not overload the power circuits, wiring, and over-current protection. To deter-
mine the possibility of overloading the supply circuits, add together the ampere ratings of all devices
installed on the same circuit as the device being installed. Compare this total with the rating limit for
the circuit. The maximum ampere ratings are usually printed on the switch, near their AC power con-
nectors.
Cautions
• Ensure the air flow around the front, sides, and back of the switch is not restricted.
• Ensure the cooling vents are not blocked.
• Do not install the switch in an environment where the operating ambient temperature might exceed
40
º C (104 º F).
