Wiring Power Supply Modules
Connecting an AC power cable
*1. 24V on the external power supply is connected to VS+ and VS- on the power supply module. VS+ and
VS- can be used to detect whether the voltage of the external power supply is stable.
*2. FG on the power supply module is connected to the control box as the functional ground.
*3. The live wire and the neutral wire in the AC power cable are connected to L and N on the power
supply module respectively. To prevent the system from becoming abnormal, the ground in the AC
power cable has to be connected to LG on the power supply module.
The power input of AHPS05-5A is the AC input. Users have to pay attention to the following points when they
use AHPS05-5A.
The alternating-current input voltage is in the range of 100 VAC to 240 VAC. Please connect the power
supply to the terminals L and N. If the 110 VAC or the 220 VAC power supply is connected to the input
terminals VS+ and VS-, the PLC will be damaged.
In order to ensure that the external power supply stably provides24 VDC power, the external power
supply can be connected to VS+ and VS-. If the PLC detects that the voltage of the external power supply
is lower than the working voltage, users can write a protective program.
The length of the cable connecting with the ground should be more than 1.6 millimeters.
If the power cut lasts for less than 10 milliseconds, the PLC keeps running without being affected. If the
power cut lasts for long, or if the voltage of the power supply decreases, the PLC stops running, and there
is no output. When the power supply returns to normal, the PLC resumes. (Users have to notice that there
are latched auxiliary relays and registers in the PLC when they write the program.)
Please use single-core cables or multicore cables. The diameters of the cables used should be in the
range of 12 AWG to 22 AWG. The torque applied to the terminal screws should be 9.50 kg-cm (8.25 Ib-in).
Please use copper conducting wires. The temperature of the copper conductive cables should be
60/75°C.
