Wiring 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 0.68 Nm (6 in-lbs).

Wire Size and Terminal Screw Torque

Each terminal accepts up to two wires with the following restrictions:

NOTE

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.

NOTE

If you need to remove the finger-safe cover, insert a screw
driver 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.
