AH Mo tion Co n tro ller – H ardw are Ma nua l4 - 1 8_4Note(1) The 110 V/220 V power cable and the 24 VDC power cable should be thick cables. (The area of thecross-section of the cable is 2 mm 2 , and the diameter of the cable is 14 AWG.) Be sure to twist the power cablesat terminal screws. To prevent the short circuit which results from loose screws, you need to use solderlessterminals 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 FGto 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 Wiring Power Supply Modules4.5.1 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 thereis much noise, connect an isolating transformer.AC power supply100-240 VAHPS05-5AI/O equipmentAnother piece of equipmentIsolating transformer(2) The 110 VAC cable, the 220 VAC cable, and the 24 VDC cable should be twisted, and connected to a modulewithin 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 shouldbe more than 100 millimeters.(4) To prevent the surge resulting from lightning, please install a surge absorber in the way shown below.AC power supply100-240VAHPS05-5AI/O equipmentSurge absorberPoints 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 theDC power supply from the power cables for I/O devices and other devices. If there is much noise, connect anisolating transformer.
