Block mounting method
Note: Refer to the figure for the dimensions of a recess for the block-mounting method.
The length (x) of a recess depends on the total number-size factor (NSF) of the flush-mounted
devices that must be installed in the recess. To calculate the length of a recess:
1. For each flush-mounted device, get the number-size factor (NSF).
2. Add the NSFs of the flush-mounted devices to get the total NSF.
3. Use the total NSF to get the length (x) of the recess from the table. The length includes
the DCN-FCOUP couple pieces.
Notice!
Install DCNM-FEC Flush end caps on the couple pieces at the two ends of the recess.
