Wire the Finger-safe Terminal Block
When wiring the terminal block, keep the finger-safe cover in place.
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 will 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 1.27 N•m (11.24 lb•in).
Wire Size and Terminal Screw Torque
Each terminal accepts as many as two wires with the following restrictions.
TIP
The terminal screws are non-captive. Therefore, it is possible to use a ring lug [maximum
1/4-inch o.d. with a 0.139-inch minimum i.d. (M3.5)] 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.
