20 C. Rectifier Sense Lead Input Jumper: This jumper needs set to match the system. If there is a sense lead fuse located in the system control section and the rectifier is connected via ribbon cable to the control section this jumper should be placed in the Remote Sense Via J1" position. If the sense lead is brought in manually to J12, put the Jumper in the Remote Sense Via J12" position. If the system uses the rectifiers in local internal sense mode, place the jumper in the local sense position. If this shelf is being added to an existing Power system and the sense mode is unknown, look into an existing shelf and put the Jumper of the new shelf in the matching position. (See Figure 2-1). On ship loose Rectifier Shelves, the jumper is shipped in the Remote Sense Via J1" position for Ribbon Cable Connection. D. FRAME GROUND AND C.O. GND Connections: Not required when installed into a PECO II power system designed for use with this rectifier shelf. Typically the frame ground of the chassis is via the bay framework that the rectifier shelf is mounted in. If this rectifier chassis is to be mounted in a non conductive framework, special provisions will have to be made by the installer to meet Telco, NEC, and UL requirements as needed. Typically the C.O. ground reference connection is made via the power system at the GND return bar. If this rectifier shelf is to be used in a special application that has no ground reference, special provisions will have to be made by the installer to meet Telco, NEC, and UL requirements as needed.

29 Table 2-8: RECTIFIER COMMON SIGNALS, J2 (INPUT) & J3 (OUTPUT) PIN # PIN NAME DESCRIPTION 1 AC FAIL AC Fail Alarm: Provides a +GND signal in the event of an AC input voltage loss to any of the rectifier modules. NOTE: A rectifier module must be installed in its slot before an AC Fail can take place. 2 RECT OK 3 RFA 4 BTC Rectifier OK Signal: Provides +GND signal with a 20KΩ impedance for each rectifier module installed in the shelf. The impedances are paralleled together for all installed modules i.e. for four installed modules the impedance would be 5KΩ. Rectifier Fail Alarm: Provides +GND signal with a 20KΩ impedance for each rectifier module in the shelf experiencing a failure condition. The impedances are paralleled together for all failed modules i.e. for two failed modules the impedance would be 10KΩ. The R48P-23 retrofit rectifier shelf does not use a resistive output. Its output is a low impedance ground signal. Battery Temperature Compensation Input: This analog input allows the rectifier module float voltage to be adjusted as a result of battery temperature in systems equipped with BTC circuitry. 5 LSO 6 HV 7 REM EQ 8-10 SENSE- Load Share Lead: Common analog lead of the modular rectifiers allowing proportional load sharing between modules. High Voltage Shutdown Input: When a BAT- signal is applied to this input all rectifier modules loaded more than 10% will be shutdown. Remote Equalize Input: When a +GND signal is applied to this input the rectifier shelf s output voltage will change to the preset equalize voltage of the rectifier modules. (-) Sense Input: This is the plant voltage sense lead for proper regulation of the rectifier modules. Operational when sense lead jumper is in "Remote". This is not used when jumper is set to "Local". See the system level information to find the proper setting for the system that the rectifier shelf is being used in. Page 28 Issue 13, October 2003
