1. A current limiting resistor can be used to limit inrush current however the operating characteristics of the ac input circuit will be affected If a 6 8K Q resistor is placed in series with the input the inrush current is reduced to 35 mA In this configuration the minimum on state voltage increases to 92V ac Before adding the resistor in a hazardous environment be sure to consider the operating temperature of the resistor and the temperature limits of the environment The operating temperature of the resistor must remain below the temperature limit of the environment 1762 IN002A US P MicroLogix 1762 IA8 120V ac Input Module Wiring the Finger Safe Terminal Block When wiring the terminal block keep the finger safe cover in place Note Finger safe cover not shown 1 Route the wire under the terminal pressure plate You can use the stripped end of the wire or a spade lug The terminals will accept a 6 35 mm 0 25 in spade lug 2 Tighten the terminal screw making sure the pressure plate secures the wire Recommended torgue when tightening terminal screws is 0 904 Nm 8 in lbs Note If you need to remove the finger safe cover insert a screw driver into one of the sguare wiring holes and gently pry the cover off If you wire the terminal block with the finger safe cover removed you will not be able to put it back on the terminal block because the wires wi2.
