General test conditions	Unless otherwise specified, parameters are measured at nominal input, rated load and 25°C ambient temperature.

Installation and system guidance

Installation safety and polarity	Disconnect the system supply before installation or maintenance and prevent inadvertent reconnection. Have faults examined by a qualified technician; do not attempt repairs yourself. Do not reverse input or output polarity. Avoid high moisture, water, fire sources and ambient temperatures beyond the model specification.
PCB clearance and ventilation	Keep at least 5 mm insulation distance around the PCB unit. Provide good ventilation and keep 10–15 cm clearance when an adjacent device is a heat source. Nonstandard mounting orientation or high ambient temperature may require output-current derating; use the model-specific mounting drawing and derating curves.
Conductor and connector selection	The installation guide recommends these wire columns: 18 AWG / 0.75 mm² for 6 A; 16 AWG / 1.00 mm² for 6–10 A; 14 AWG / 1.5 mm² for 10–16 A; 12 AWG / 2.5 mm² for 16–25 A; 10 AWG / 4 mm² for 25–32 A; and 8 AWG / 6 mm² for 32–40 A. These are paired guide entries, not exact unit conversions. When five or more wires connect to the unit, derate each listed wire-current recommendation to 80%. Select compatible mating housings and terminals from this model’s connector specification.
Rated loading and system inrush	Keep output current and power within the selected model’s ratings and applicable derating conditions. The system may require an additional inrush-current limiting circuit; consult MEAN WELL if the system requirement is uncertain.
System enclosure and grounding	Install this component converter inside the final system enclosure. The surrounding equipment enclosure must have flammability rating V1 or better.
Complete-system EMC verification	Recheck EMC with the converter installed in the final equipment and connected to a representative load. Wiring and assembly affect the result; the linked component EMI guidance does not certify the finished equipment. The PSD-15 datasheet’s 230 × 230 × 1 mm metal plate describes the EMC test arrangement, not a required installation clearance.
