For optimum EMI performance, the power supply should be mounted to a metal plate grounded to all 4 mounting holes of the power supply. To comply with
safety standards, this plate must be properly grounded to protective earth (see mechanical dimension notes). Pre-compliance testing has shown the stand-
alone power supply to comply with EN55022 class A radiated emissions. Radiated emission results vary with system enclosure and cable routing paths.
SAFETY CONSIDERATIONS
1. This power supply is a component level power supply intended for use in class I or class II applications. Secondary ground traces need to be suit-
ably isolated from primary ground traces when used in class II applications.
2. When the power supply is used in class II equipment, all ground traces and components connected to the primary side are considered primary for
spacing and insulation considerations.
3. Double pole/neutral fusing.
