DANGER:
When operating power-supply equipment, you must follow basic safety
precautions to reduce the risk of fire, electric shock, and personal injury.
Read and understand all instructions. Follow all warnings and instructions
marked on the products. Follow all the installation instructions when
mounting the product.
Never use a power unit with a power source other than that specified on the
product labels.
Do not try to plug the 3-wire grounding plug into a nongrounding power
outlet. This plug only fits into a grounding power outlet. This is a safety
feature. If you are unable to insert the plug into the outlet, have an electrician
replace the outlet. Do not defeat the safety purpose of the grounding plug.
Do not attach the power supply cord to building surfaces.
Do not overload power outlets.
Do not use this product near water. Do not let anything spill on or into the
unit. Clean only with a dry rag.
Never push objects through openings in the case.
Do not try to disassemble the unit. Return it for repair. Opening or removing
covers may expose you to dangerous voltages. Incorrect reassembly may
cause electric shock when the products are subsequently used.
Power down the unit and refer servicing immediately if the unit is exposed to
water or other liquids, if the unit is dropped or damaged, or if the unit fails to
operate normally.
Never let the operating temperature of the unit exceed the recommended
maximum.
