INSTRUCTION MANUAL
6-3 Mounting Method
1)
This is forced air cooling type power supply. In consideration of the heat radiation and safety, please keep a distance
of more than 50mm between the power supply front & back.
2)
Maximum allowable penetration of mounting screws into the power-supply is 5mm.
3)
Recommended torque for mounting screws (M4): 1.27 N
m (13.0 kgf
cm).
4)
For /L option, please provide clearance 4mm or more on top of power supply to peripheral parts.
7. Wiring Method
The input and output load wires shall be separated to improve noise immunity.
Both wires must be as thick and short as possible to have 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
terminal of GWS500 series to mounting set ground terminal

Note 1 :
When using separate loads, it is recommended to use 4 pieces of 0.8mm thick crimp-type terminal.
Note 2 :
For recommended wire diameter, refer to wire maker recommended allowable current and voltage drop.
8. External Fuse Rating
Refer to the following fuse rating when selecting the external input fuse. Surge current flows when input turns on. Do
not select the fuse according to input current (rms) values under the actual load condition.
