This will not have an impact if a product is marked with an input voltage range such as 200-240 V (servers are marked like this). 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.
