MicroLogix 1400 Programmable Controllers DIN Rail Mounting The maximum extension of the latch is 14 mm (0.55 in.) in the open position. A flat-blade screwdriver is required for removal of the controller. The controller can be mounted to EN50022-35x7.5 or EN50022-35x15 DIN rails. DIN rail mounting dimensions are shown below.
Page 14
MicroLogix 1400 Programmable Controllers Follow these steps to remove your controller from the DIN rail. 1. Place a flat-blade screwdriver in the DIN rail latch at the bottom of the controller. 2. Holding the controller, pry downward on the latch until the latch locks in the open position.

MicroLogix 1400 Programmable Controllers Wiring Recommendation When wiring without spade lugs, keep the finger-safe covers in place. Loosen the terminal screw and route the wires through the opening in the finger-safe cover. Tighten the terminal screw, making sure the pressure plate secures the wire. Finger-safe cover 44527 ATTENTION...

MicroLogix 1400 Programmable Controllers Spade Lug Recommendation The diameter of the terminal screw head is 5.5 mm (0.220 in.). The input and output terminals of the MicroLogix 1400 controller are designed for the following spade lugs. The terminals will accept a 6.35mm (0.25 in.) wide spade (standard for #6 screw for up to 14 AWG) or a 4 mm (metric #4) fork terminal.

MicroLogix 1400 Programmable Controllers Grounding the Controller In solid-state control systems, grounding and wire routing helps limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the ground screw of the controller to the ground bus prior to connecting any devices. Use AWG #14 wire. For AC-powered controllers, this connection must be made for safety purposes.

MicroLogix 1400 Programmable Controllers Minimizing Electrical Noise on Analog Channels Inputs on analog channels employ digital high-frequency filters that significantly reduce the effects of electrical noise on input signals. However, because of the variety of applications and environments where analog controllers are installed and operated, it is impossible to ensure that all environmental noise will be removed by the input filters.
