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’s 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.
