Procedure
Follow the instructions below to connect the communications cable to the terminal block.
WARNING! Tighten all terminal screws according to the specified tightening torque. Tightening screws too tight could damage the
terminal block, and leaving screws too loose can cause a short-circuit or drive malfunction.
1.
Connect the communications cable to the terminal block as shown in the diagram below.
Note: Communication lines should be separated from main circuit wiring and other electrical lines. (Tightening torque: 0.5 to 0.6
(N
x m) or 4.4 to 5.3 (inch-lbs)) for Network Cable Wiring.

2.
Ensure all wiring connections are tightened and wire insulation is not pinched in the terminal block. Remove any
stray wire strands that touch other terminals.
3.
After the terminal block is fully attached to the option card, tighten the screws on the left and right sides of the
terminal block. (Tightening torque: 0.5 to 0.6 (N
x
m) or 4.4 to 5.3 (inch-lbs)).
