Note
(1)
The 110 V/220 V power cable and the 24 VDC power cable should be thick cables. (The area of the
cross-section of the cable is 2 mm
at terminal screws. To prevent the short circuit which results from loose screws, you need to use solderless
terminals with insulation sleeves.
(2)
If cables are connected to the terminals LG and FG, the cables need to be grounded. Do not connect LG and FG
to any devices. If LG and FG are not grounded, the PLC will be susceptible to noise. Since LG have potential,
you will get an electric shock if you touch metal parts.

4.5.1 Precautions
Connecting AC power cables
(1)
Please separate the power cable of AHPS05-5A from the power cables for I/O devices and other devices. If there
is much noise, connect an isolating transformer.
AC power supply
100-240 V

(2)
The 110 VAC cable, the 220 VAC cable, and the 24 VDC cable should be twisted, and connected to a module
within a short distance.
(3)
Do not bundle 110 VAC cable, the 220 VAC cable, the 24 VDC cable, the (high-voltage high-current) main circuit,
and the I/O signal cable together. Besides, it is recommended that the distance between adjacent cables should
be more than 100 millimeters.
(4)
To prevent the surge resulting from lightning, please install a surge absorber in the way shown below.
Points for attention:
1. The surge absorber and the PLC system should be grounded separately.
2. Please select the surge absorber whose working voltage is not less than the maximum allowable input voltage.
Connecting DC power cables
(1)
AHPS15-5A is independently supplied with power by a DC power supply. Please separate the power cable of the
DC power supply from the power cables for I/O devices and other devices. If there is much noise, connect an
isolating transformer.
