NT5C06B / C   Installation and User Manual 

This appendix provides additional information about the NT5C10BF-1 

(brown) and NT5C10BP (grey). 

The NT5C10BF-1 and NT5C10BP power shelves  are used in the FTIP and 

FTOP application. This power shelf provides housing for two MPR15E 

rectifiers plus one 50 A LVD, FTIP application, or three MPR25EX 

rectifiers, FTOP application. In both applications the rectifier in the center 

will be wired for standby operation (standby means that this rectifier will be 

inhibited under normal operation and will become active when another 

rectifier in the same power shelf issues an RFA). 

The MPR15E (NT5C06CB/CD) rectifier is used in this application. Two 

rectifiers maximum can be used in each system, plus one 50 A LVD. The 

main rectifier is active and carries the load, and the standby is inhibited. It 

will be activated upon removal or failure of the main rectifier (hot standby 

model). 

During transfer from a failed “MAIN” unit to a “STANDBY” unit the load 

current will be supplied by the backup batteries. The standby unit will 

provide the required current within 10 seconds.
