Chapter 2 Hardware Setup 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. Surge absorber AC power supply 100-240V 2_ 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. Isolating transformer AHPS15-5A AC power supply 100-240 V 24 V DC DC power supply I/O equipment Another piece of equipment 2.
