(2) Condition to meet Isolation & Withstand Voltage standard
keep 4mm space from the top and sides of power supply.
And keep 8mm space from the solder surface of PCB.
(3)
must be connected to the Protective earth terminal of the equipment. Also 2 mounting holes are must be
connected to the Chassis (Conductor) by Metal spacer. When screw clamping the mounting holes, please
use the screw with spring washer. If not connect to the Chassis (Conductor), the conducted noise, radiation
noise and output noise will increase. (The location of 2 mounting holes for Chassis connection is shown
with
mark in below figure.)
8. Wiring Method
(1) The output load line and input line shall be separated, and use all lines as thick and short as possible to make
lower impedance. The output load line and input line shall be twisted or use shielded wire to improve noise
sensitivity.
(2) Input/Output lines shall be twisted and separated from the output lines.
(3) Noise can be eliminated by attaching a capacitor to the load terminals.
(4) For safety and EMI considerations, connect between terminal of input connector and protective earth terminal
firmly.
(5) The recommended wire type, torque and crimp-type terminal :
Input
：
AWG#22 ~ AWG#18
Output
：
AWG#22 ~ AWG#16
