When the rectifier is installed in an embedded shelf, the RC+, RG-, EQL (if equipped) and RFA monitoring signals are extended by the cable assembly which is fed through the rear of the shelf.

The connections available from the rectifier interface connector located at the rear of the unit are described in the “Rectifier and controller interface connections” section of this manual.

Refer to the reference section for all the interface signal wiring information for each shelf model number.

Following is a brief description of special interface or alarms signals for specific applications.

NT5C10BA-1/2, NT5C10BF-1 and NT5C10BP hot standby power shelf

The NT5C10BA-1/2, NT5C10BF-1 and NT5C10BP wiring is such that when the power shelf is equipped with two or more rectifiers, one rectifier is inhibited (Standby) and will be activated when one rectifier (Main or Regular) fails.

These power shelves are equipped with a relay that provides an alarm signal no standby rectifier (NSR) when the standby rectifier is missing from its position. Also two RFA signals are available for transmitting the alarm signal to the monitoring unit.

Note : The earlier vintage "Main" rectifier has been referred to as the "Regular" rectifier. See Appendix A for additional information on the NT5C10BF and NT5C10BP shelves.
