Installation and Wiring Chapter 3
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.
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:
Wiring the Modules
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.
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.

ATTENTION: To prevent shock hazard, care should be
taken when wiring the module to analog signal sources.
Before wiring any module, disconnect power from the
system power supply and from any other source to the
module.
