5-2 Mounting Method
1) This is convection cooling type power supply. In
the consideration for the heat radiation and safety.
Please keep a distance 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 6mm.
3) Recommended torque for mounting screw

6. Wiring Method
The output load line and input line shall be
separated and twisted to improve noise sensitivity.
Use all lines as thick and short as possible to
make lower impedance.
Noise can be eliminated by attaching a capacitor
to the load terminals.
In SWS150, the output current of each output
terminal is limited to 20A. When it is more than
20A, please use 2 terminals together.
For safety and EMI considerations, connect the
FG terminal of SWS series to mounting set
ground terminal.
The recommended torque for the terminal piece:
(M3.5 Screws) : 0.74N
