Emerson MPR15 Series, MPR25 Alarms, Power and signal lead termination, Factory set voltage limits

102 Appendix A: NT5C10BF-1 and NT5C10BP

Alarms

Available alarms for monitoring the status of the FTIP power system are as follows:

-LVA Battery Return (RTN)

-LVDA Battery Return (RTN)

-RFA Battery Return (RTN)

-NSR (No Standby Rectifier) Battery Return (RTN)

Power and signal lead termination

The power and signal cables are terminated as follows:

a)	Power cables:
	-Battery Return (RTN A)	TB1-1 (white with red tracer)
	-Battery (-48 A)	TB1-2 (Red)
b)	Signal cables:
	-Negative Sense (RC-)	TB1-1 -48V
	-Positive Sense (RG+)	TB1-2 RTN
	-Jumper (see Note below)	TB1-3
	-Jumper (see Note below)	TB1-4
	-Rectifier Fail (RFA)	TB1-5
	-No Standby Rectifier (NSR)	TB1-6
	-Low Voltage Disconnect (LVDA)	TB1-3 part of LVD unit
	-Low Voltage Alarm (LVA)	TB1-6 part of LVD unit

Note: When the Main 2 rectifier is missing TB1-3 and TB1-4 must be strapped together.

Factory set voltage limits

Refer to User Manual (UM) 167-7011-010 Voltage Level Limits for Power Plants, Rectifiers and Controllers.

FTOP application

The MPR25EX rectifier will be used in FTOP applications. Three rectifiers maximum can be used for a system. One or two of the rectifiers (Main) are active and carry the load, while the other (standby rectifier) is inhibited. It will be activated upon failure of one of the main rectifiers. The rectifier at the center will be wired as standby and the other rectifiers will be active. The maximum power capacity of the system is 50 A.
