INSTRUCTION MANUAL
7. Wiring Method
 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 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 FG terminal of GWS250 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
drop. For higher output current model like 12V, bigger diameter wire is recommended.
8. External Fuse Rating
Refer to the following fuse rating when selecting the external input fuse. Surge current flows when input turns on.
Fuse rating is specified by Inrush Current value at input turn on. Do not select the fuse according to input current (rms)
values under the actual load condition.
