The cFP-PWM-520

 

mounts on a Compact FieldPoint backplane 

(cFP-BP-x or cFP-180x), which provides operating power to the 
module. Installing the cFP-PWM-520 onto a powered backplane 
does not disrupt the operation of the bank.

To install the cFP-PWM-520, refer to Figure 2 and complete the 
following steps:

1. Align the captive screws on the cFP-PWM-520 with the screw 

holes on the backplane. The alignment keys on the 
cFP-PWM-520 prevent backward insertion.

2. Press firmly to seat the cFP-PWM-520 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.
