LED load and application conditions

Load application	LED lighting and moving-sign applications.
LED drive method	Use the constant-current region for direct LED drive. Direct connection to LEDs is suggested; this supply is not suitable for use with additional drivers.
LED-system compatibility	The highest output voltage within the constant-current region depends on the configuration of the end system. Contact MEAN WELL if compatibility issues arise.
Switched-mains installation	To meet the stated ErP lighting-fixture requirements, use this supply behind a switch; do not leave it permanently connected to the mains.
China lighting application	The datasheet states that this product is not suitable for LED lighting applications in China and recommends the LPF, NPF, XLG, XLC or XLN series for those applications.

General test conditions	Unless otherwise specified, parameters are measured at 230 VAC input, rated load and 25°C ambient temperature.

Installation and system guidance

Installation isolation and service	Disconnect the supply from the mains before installation or maintenance and prevent unintended reconnection. Have faults examined by a qualified technician; do not open the case yourself. Any adjustment requiring case removal must be performed by qualified personnel with mains disconnected, following the model drawing and safe reassembly requirements. Dispose of the LED supply together with the lighting equipment at end of life.
Ventilation and mechanical support	Keep ventilation clear and do not stack objects on the unit. Maintain 10–15 cm clearance when an adjacent device is a heat source. Follow this model’s mounting orientation and derating diagrams. Check the mounting surface and luminaire structural strength; use safety cables for bay lighting applications. For IP64 units, use indoors or outdoors only where sheltered from rain. Do not immerse the unit in water.
Wiring and system enclosure	Use approved input and output wiring with current ratings at least equal to the applicable unit current. Follow this model’s terminal assignments. This Class II ungrounded supply has no FG connection. Provide insulation around system interconnections and enclose single-insulated wiring. Keep output current and power within the model ratings and temperature limits. Have damaged external flexible cables replaced by the manufacturer, its service agent or similarly qualified personnel.
Circuit-breaker reference	At 230 V AC, the installation manual gives calculated maximum quantities for PLN-30 with ABB S200-series breakers: B10 40, B16 64, C10 40, C16 64, D10 40 and D16 64. B, C and D identify breaker trip curves; 10 and 16 identify ampere ratings. These counts apply to that stated breaker and voltage reference.
EMC integration	Reverify EMC in the finished equipment with the connected load and actual wiring and assembly. The linked guidance describes representative component-power-supply tests; its illustrated distances are test arrangements, not installation clearances.
