14 MicroLogix™ 1500 Programmable Controller Base Units
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.

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 1500 base unit 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.
When using spade lugs, use a small, flat-blade screwdriver to pry the finger-safe
cover from the terminal blocks, then loosen the terminal screw.
