5-2 Mounting Method
1) 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.
2) The maximum allowable penetration of mounting screws is 5mm.
3) Recommended torque for mounting screw LS50, LS75, LS100 & LS150 (M3 screw) : 0.49 N⋅m (5.0 kgf⋅cm).
