Mounting Method
(1) This is convection cooling type power supply. In consider-
ation of the heat radiation and safety, please keep a distance
of more than 15mm between the power supply and the pe-
ripheral parts. When lining up multiple units, please make
sure to place them 15mm or more apart from each other.
(2) Maximum allowable penetration of mounting screwsinto the
power-supply is 5mm except LS25 (4mm).
(3) Recommended torque for mounting screws of LS25 to
LS150 (M3 screw) : 0.49 N·m (5.0 kgf·cm).
Air Flow

15mm or more
Provide punching, etc.to allow air to pass.
