Removing the Finger-Safe Terminal Block

To remove the terminal block, loosen the upper and lower retaining screws. The

terminal block will back away from the module as you remove the screws. When

replacing the terminal block, torque the retaining screws to 0.46 N•m

(4.1 lb•in).

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.

WARNING: When you connect or disconnect the Removable Terminal

Block (RTB) with field side power applied, an electrical arc can occur. This

could cause an explosion in hazardous location installations.

Be sure that power is removed or the area is nonhazardous before proceeding.

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.
