Wiring the Finger-Safe Terminal Block

When wiring the terminal block, keep the finger-safe cover in place.

1. Route the wire under the terminal pressure plate. You can use the stripped end of the

wire or a spade lug. The terminals will accept a 6.35 mm (0.25 in.) spade lug.

2. Tighten the terminal screw making sure the pressure plate secures the wire.

Recommended torque when tightening terminal screws is 0.904 Nm (8 lb-in.).

3. After wiring is complete, remove the debris shield.

Wire Size and Terminal Screw Torque

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

ATTENTION

Be careful when stripping wires. Wire fragments that fall into a module
could cause damage when power is applied. Once wiring is complete,
ensure the module is free of all metal fragments.

TIP

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.
