6. Wiring Method
This is convection cooling type power supply. In consideration of the heat radiation and safety, please keep a dis-
tance of more than 15mm between the power supply and the peripheral parts. When lining up multiple units, please
make sure to place them 15mm or more apart from each other.
Maximum allowable penetration of mounting screws into the power-supply is 5mm except LS25 (4mm).
Recommended torque for mounting screws of LS25 ~ LS150 (M3 screw) : 0.49 N⋅m (5.0 kgf⋅cm).
The input and output load wires shall be separated and twisted to improve noise immunity.
Both wires must be as thick and short as possible to make lower impedance.
Noise can be reduced by connecting a film capacitor with 0.1uF capacitance across the load terminals.
For safety and EMI considerations, connect the FG terminal of LS series to mounting set ground terminal.
The recommended wire type :
Note 1 : When using separate loads, it is recommended to use 2 pieces of 0.8mm thick crimp-type terminal.
Note 2 : For recommended wire diameter, refer to wire maker recommended allowable current and voltage
