Terminal Door Label
A removable, write-on label is provided with the module. Remove the
label from the door, mark your unique identification of each terminal
with permanent ink, and slide the label back into the door. Your
markings (ID tag) will be visible when the module door is closed.
Removing and Replacing the Terminal Block
When wiring the module, you do not have to remove the terminal
block. If you remove the terminal block, use the write-on label located
on the side of the terminal block to identify the module location and
type.
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. Be careful not to damage the CJC sensors. When
replacing the terminal block, torque the retaining screws to 0.46 Nm
(4.1 in-lbs).
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 accept a 6.35 mm (0.25 in.)
spade lug.
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.
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).
NOTE: 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 may not be able to put it back on the terminal block
because the wires will be in the way.
