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.

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.5 _% b1 F+ G% p* i2 A8 `+ F+ E) P

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.
