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 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 [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 may not be able to put it back on the terminal block because
the wires will be in the way.
