※Input:18AWG black and white to be connected to ac l and n ,Green wire go ground,
※Output wire: 16AWG , red is（DIM+）,Black is（DIM-）
※Class 2 standard output terminal. three groups of cables for SMT-012-300VTHJ / SMT-012-300VTHJV2 / SMT-012-300VTHJWV2 ; two groups for SMT-024-288VTHJ/ SMT-024-288VTHJV2 / SMT-024-288VTHJWV2
■Dimming operation
※The Pulse-Width modulation (PWM) of output voltage can be adjusted through input terminal of the ac phase line(L) by connection a phase/triac dimmer.
※Usually matching with forward phase , leading edge , magnetic low voltage, triac dimmers, or reverse phase, trailing edge ,Electric low voltage Dimmers.
※Please try to use dimmers with power at least 1.5 times as the output power of the driver.
■Derating curve
※To extend their life, please refer to the derating curve and derate according to the temperature.

■ Instruction:
※This driver should be installed by qualified and professional person;
※Please make sure the driver is installed with adequate ventilation around it to allow for heat dissipation.
※Ensure that wiring is correct before test in order to avoid light and power supply damage;
※If the dimmable led drivers do not work normally, pl. don’t maintain privately, but contact us: sales9@smartselectronics.com or take a phonecall: 0086-18016688251
