Installing Connector Blocks on the Backplane
In order to connect I/O modules to input signals or to external loads, you
need to install a cFP-CB-
x
connector block or other connectivity accessory
for each I/O module on the backplane. Use the connector socket to the right
of each I/O module socket.
1.
Align the captive screws on the connector block with the holes on the
backplane. The shape of the I/O connector on the connector block
prevents backward insertion.
2.
Press firmly to seat the connector block on the backplane.
3.
Using a number 2 Phillips screwdriver with a shank of at least 64 mm
(2.5 in.) length, tighten the captive screws to 1.1 N
⋅
m (10 lb
⋅
in.) of
torque. The nylon coating on the screws prevents them from loosening.
