CHAPTER 7 LOAD CONNECTION DESCRIPTION
7-1. WIRING INTRODUCTION
Notice: Please ensure the mains supply is turned off before wiring!!
(1) Using the proper wires can avoid the attenuation characteristics. Please refer to the table below.
(2) The flexible wire is recommended.
(3) When the diameter of wire is smaller than the required one in the following table, please combine
two wires in
parallel with the same diameter and length.
(4) The wire and voltage drop reference table:

Example: When using 10AWG wire with 5m length, and current flow is10A, the voltage drop goes to 0.999x3x10
approx. 164mV.
7-2. OUTPUT CONNECTION WITHOUT REMOTE SENSE
(1) Wiring diagram:
(2) Wiring description:
Refer to the above diagram, the +/- sense wiring is connected to the output terminal, and that will bring out the
voltage drop. For example, the wire resistance is r1 & r2, and voltage drop is calculated as I x r1+ I x r2. The front
panel displays the voltage of output terminals, so the voltage of load side will be equal to the value of that output
terminal voltage deducts the dropped voltage (I x r1+ I x r2). The above wiring method is recommended for the high
noise or switching mode load such as: DC TO DC, DC TO AC
