Important: Remove power from the controller before
beginning this procedure. Failure to de-energize the controller can result in
equipment damage.
Important: It is best practice to remove the terminal block
from the pin headers on the unit before wiring the terminal blocks.
Do not use more force than is necessary when tightening the terminal block
screws. To prevent applying excessive force when tightening the screws, apply
the following steps:
-
Tighten the terminal screws until the screw is snug on the wire, and then
tighten the screw an additional quarter (90°) to half (180°) turn.
-
Only use enough downward force necessary to keep the screwdriver bit engaged
with the screw. Too much downward force while tightening the terminal screws can
damage the terminal.
If a terminal block exhibits any symptoms of damage, replace
the terminal block. For detailed information about replacing terminal
blocks, refer to the Terminal Block Retrofit Installation Guide
(LIT-12014622).
