Chapter 3 Installation and Wiring
Follow these steps.
1. Loosen the terminal screws to be wired.
2. Route the wire under the terminal pressure plate.
You can use the bare wire or a spade lug. The terminals accept a 6.35 mm
(0.25 in.) spade lug.
3. Tighten the terminal screw making sure the pressure plate secures the wire.
Recommended torque when tightening terminal screws is 0.68 N•m
(6 lb•in).
Wire Size and Terminal Screw Torque
Each terminal accepts up to two wires with these restrictions.
TIP The terminal screws are non-captive. Therefore, it is possible to
use a ring lug (6.35 mm (0.25 in.) maximum outside diameter with
3.53 mm (0.139 in.) minimum inside diameter) with the module.
TIP If you need to remove the finger-safe cover, insert a screwdriver
into one of the square, 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 will be in the way.
