Wire the Terminal Block
When wiring the terminal block, keep the finger-safe cover in place.
1. Loosen the retaining 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 retaining screw and make sure that the pressure plate secures
the wire.
Recommended torque when you tighten the retaining screws is
0.68 N•m (6 lb•in).
Wire Size and Terminal Screw Torque
Each terminal accepts one or two wires with the following restrictions.
TIP The retaining screws are non-captive. You can use a ring lug [maximum
6.35 mm (0.25 in.) o.d. with a 3.53 mm (0.139 in.) minimum i.d. (M3.5)]
with the module.
TIP If you must remove the fingersafe 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 fingersafe cover removed, you cannot put it back on the
terminal block because of wires in the way.
