You do not have to remove the lead wires from the terminal block in or- der to remove the block from an I/O Unit. Terminal block mounting screws Loosen the terminal block mounting screws to remove the terminal block from the I/O Unit. Make sure the mounting screws on the terminal block are tightened af- ter wiring is complete and the terminal block is re- mounted to the I/O Unit. 3-5-2 Wiring Precautions General Electrical Noise Take appropriate measures when any electrical device likely to produce noise is connected to the PC as a load. Devices generating noise of more than 1,200 V (such as electromagnetic relays and valves) require noise suppression. For noise sources running on DC power, connect a diode in parallel with the coil of each device. When mounting a CPU Rack and an Expansion I/O Rack together on a mounting plate, provide a ground to the mounting plate. The mounting plate must be plated with a highly conductive surface in order to ensure noise immunity. Wiring I/O Units Section 3-5 |
