instruction manual before using the power supply unit pay attention to all warnings and cautions before using the psu. incorrect usage could lead to an electrical shock, damage t o the psu or a fire hazard. warning & caution ?do not modify and remove the cover. ?if any failure or trouble occurs because of utilizing the pow er supply unit without reflecting the described contents on this specification, murata cannot ass ure such trouble. ?do not touch the internal com ponents, they may have high volt age or high temperature. you may get electrical shock or burned. ?definitely avoid to use the power supply unit by the excessi ve input voltage, output voltage, output current and ambient temperature as defined on this sp ecification. the excessive current, voltage and temperature will cause th e deterioration of the components or abnormal heat, both of which may affect not only to shor ten the unit's life-long but also to damage and break the unit. in a case of led vf 30v or less because of led chip dispersio n, please make sure to evaluate and confirm the quality upon mounting the power supply unit to your product. but don't use it under the led vf 25v or less. ?use the psu after confirm t he correct connection of input and output. ?be sure not to scratch and dama ge the input leads. never tran sfer the unit by holding and pulling any lead wire. if psu i d d b l t l t t it product specification mpa1948 y series power supply for led ?if psu is dropped, absolutely not to use it any more. ?make sure not to install and/or store the unit under the envi ronment as stated below because such will cause the insulation deterioration. make sure to avoid storing the unit under the condition of high temperature, high humidity or direct sunlight which are out of the standard on this specification. ambient air containing the corrosive gas. (cl2, h2s, nh3, so2, nox, etc.) places which have the fear to be splashed with water, oil, org anic solvent, etc. places with a high concentration of dusty places. other environment correspondingly mentioned above. ?make sure not to install and/or store the unit under the envi ronment as stated below because such will cause the insulation deterioration. if any alien substance attached on terminals, it may cause the contact failure or insertion deterioration. the use of the silicon rubber or silicon bond which contain a high percentage of dimethylpolysiloxane may cause to trigger the contact failure o f volume, potentiometer volume or switch. make sure to use such rubber or bond with the percentage of dimethylpolysiloxane 0.1% or less. ?psu can not be used under the condition of the series operati on. ?rust may occur in the chassis because of use environment. ?this specification regulates the quality of the power unit, i f nothing specially defined. when using the power supply unit, make sure to evaluate and confirm the quality upon mounting the power supply unit to your product. product specification 6/8 mpa1948series
mounting ?please use the place at 50 or less around the psu ambient. ?please connect the thick and short wire to the fg terminal for safety and emi. ?please separate input wire and output wire surely. ?please refer as follows about the recommended wire for input, output and dimming. ac-intput wire0.8-1.6mm0.5-2.5mOsingle wirestrip length 9-10mm) led output wire/dimming wire for dali and pwm 0.8-1.2mm0.5-1.5mO single wirestrip length 9-10mm) ?please fix a screw about the installation of the power supply more than one place of one side.
