2. Align the FP-DO-403 alignment slots with the guide rails on 

the terminal base.

the module is firmly seated, the terminal base latch locks it into 
place.

Figure 1.  Installing the FP-DO-403

The cFP-DO-403

 

mounts on a Compact FieldPoint backplane 

(cFP-BP-x), which provides operating power to the module. 
Installing the cFP-DO-403

 

onto a powered backplane does not 

disrupt the operation of the bank.

To install the cFP-DO-403, refer to Figure 2 and complete the 
following steps:

1. Align the captive screws on the cFP-DO-403

 

with the screw 

holes on the backplane. The alignment keys on the 
cFP-DO-403

 

prevent backward insertion.

2. Press firmly to seat the cFP-DO-403

 

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.
