This will have an impact a product is marked with a single input voltage such as 230 V or 115/230 V (desk top units are marked 115/230 V). In this case the heating test of 4.5 of IEC 60950-1 may need to be repeated at 198 V.

Dell currently designs equipment for 3048 m ( 10,000 feet ). Therefore, (unless clearances for 5000 m are used) the following symbol and instructions must be provided. All Dell equipment with CCC marking is impacted unless we redesign the equipment for 5000 m.

NOTE – For example, for 230 V equipment the clearance required for basic insulation is 2 mm. Dell requires this clearance to be 2.28 mm. For China and 5000 m 2.96 mm would be the require clearance distance.
