15. Wiring Method

(1)The output load line and input line should be separated. 
(2)Use all lines as thick and short as possible to make lower impedance. When attach the battery or large capacitance 

capacitor to the line, please attach them 1.5M apart from converter terminal. The lines shall be twisted or use 
shielded wire to improve noise sensitivity. 

(3)Noise can be reduced by attaching a capacitor to the load terminals.
(4) For safety and EMI considerations connect      terminal to the mounting set ground terminal by thick wire
( 5 )If  lighting  s u r g e   protection  is  required,  please  place  it  in  front  of  the  converter.  There  is  no  protection  against 

lighting surge inside the converter.

15-1.  Inserting contact into housing

(1)Do not apply any pulling force to crimped part and insert contact straightly to housing.
(2)Insert contact into housing, without stopping, to its furthest extent.
(3)Check secure locking on each insertion by pulling wire softly in order to check that contact does not come off 

housing. Besides, check whether there is the backlash in the direction of insertion axis.

15-2.  Mating and Un-mating connector

Hold receptacle housing securely and insert into header straight against to headed post until click sounds. Hold all 
wire securely and fix receptacle housing by fingers so as to unplug and then withdraw it on the mating axis.

 

15-3.  Routing of Wire

Routing wire so as not to apply external force to connector except force such as extent that bend the wire slightly, 

considering an enough length to route and fixing of wire.

16

 External Fuse Rating

Refer to following fuse rating when selecting external fuses that are to be used on input line.
Surge current flows when line turn on.
Do not select the fuse with input current values under the actual load condition.
