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.
