14. 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. 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.
14-1. 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.
14-2. 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.
14-3. 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.

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.
HVDC (DC320V): 20A Fast Blow type
LVDC (DC48V): 125A Fast Blow type
22/23
