3 Installation and Wiring 3-2 Equipment Wiring This section describes the wiring of the NB Unit and CP1E. 3-2 Equipment Wiring Precautions for Safe Use • Do not connect an AC power supply to the DC power terminals. • Use a DC power with a slight voltage fluctuation and reinforced or double insulation, and that will provide a stable output even if the input is momentarily interrupted for 10 ms. Rated Power Supply Voltage: DC 24 V (Allowable range DC 20.4 ~ 27.6 V) The connectable power supply specifications are as follows: figure out a suitable power supply specification so as to satisfy the requirement for power supply capacity. 3 z NB5Q/NB7W/NB10W-TW ……
