Incorrect usage could lead to an electrical shock, damage to 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 power supply unit without reflecting the described contents on this specification, Murata cannot assure such trouble. ・Do not touch the internal components, they may have high voltage or high temperature. You may get electrical shock or burned. ・Definitely avoid to use the power supply unit by the excessive input voltage, output voltage, output current and ambient temperature as defined on this specification. The excessive current, voltage and temperature will cause the deterioration of the components or abnormal heat, both of which may affect not only to shorten 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 dispersion, 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 the correct connection of input and output. ・Be sure not to scratch and damage the input leads. Never transfer the unit by holding and pulling any lead wire. ・If If PSU iis ddropped, d absolutely b l t l nott tto use it any more. ・Make sure not to install and/or store the unit under the environment as stated below because such will cause the insulation deterioration. ① 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. ② Ambient air containing the corrosive gas. (Cl2, H2S, NH3, SO2, NOX, etc.) ③ Places which have the fear to be splashed with water, oil, organic solvent, etc. ④ Places with a high concentration of dusty places. ⑤ Other environment correspondingly mentioned above. ・Make sure not to install and/or store the unit under the environment as stated below because such will cause the insulation deterioration. ① If any alien substance attached on terminals, it may cause the contact failure or insertion deterioration. ② The use of the silicon rubber or silicon bond which contain a high percentage of dimethylpolysiloxane may cause to trigger the contact failure of 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 operation. ・Rust may occur in the chassis because of use environment. ・This specification regulates the quality of the power unit, if 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 MPA1948 Series 6/8 PRODUCT SPECIFICATION MPA1948 Series Power Supply for LED 【Mounting】 Mounting method ・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 wire：φ0.8-1.6mm，0.5-2.5m㎡ single wire （Strip length 9-10mm) LED Output wire/Dimming wire for DALI and PWM： φ0.8-1.2mm，0.5-1.5m㎡ single wire （Strip length 9-10mm) ・Please fix a screw about the installation of the power supply more than one place of one side.
