used for other purposes.
The schematic diagram of AC power supply wiring in main/expansion units is shown below. Also be cautious
about the following:
Please follow the wiring schemes regulated by local national standards to use single-pole switch（break hot wire
〝L〞 ）, or double-pole switch（break both〝L〞and〝N〞 ）, to turn on or off the AC input power.
In wiring, hot wire〝L〞must be connected to the L
N terminal. Please use wires with diameters 1mm
All G terminals on main unit and expansion unit/module have to be connected to the EG (Earth Ground)
terminal of main power system as shown in the figure below, with wire diameters larger than 2mm
Output of power for sensor cannot be connected in parallel with other powers, in which the conflict between two
sets of power will decrease their lifetime or cause immediate damage. This will induce unexpected malfunction of
PLC and cause serious or even deadly damage to people or equipment.

5.2 Specifications and Wiring of DC Power Sourced Power Supply

The available DC power sourced power supplies of FB
main unit, the 24 Watt (SPW24-D/12D24) supply for 20~60PTs main/expansion unit, and the 14 Watt expansion supply
(FB -EPW-D24) for expansion modules. Besides the FB
S
SPW24-D12/D24 are to be installed on a main unit or inside an expansion unit, where their appearances are invisible.
