Procedure
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:
-
If available, use a torque screwdriver to tighten the screw to
.25 NM (2.212 in. lbs.). The recommended bit size for the universal screws on
the terminal blocks is a Phillips #1, or a slotted 1/8 in. (3.0mm) bit.
-
If a torque screwdriver is not available, tighten the terminal
screws until the screw is snug on 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.
Note: It is best practice to remove the connector block
from the pin headers on the unit before wiring the terminal blocks. The best
way to prevent any contact damage is to avoid torquing the terminal screws
while the plugs are attached to the pin headers.
