wire. Recommended torque when tightening terminal screws is 0.68 Nm
(6 in-lbs).
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.

2.8.4 Wiring the Module
SHOCK HAZARD
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.
After the module is properly installed, follow the wiring procedure below, using
the Belden 8761 cable.
To wire your module follow these steps.
1. At each end of the cable, strip some casing to expose the individual
wires.
2. Trim the signal wires to 2-inch (5 cm) lengths. Strip about 3/16 inch (5
mm) of insulation away to expose the end of the wire.
