Pin # Signal Name Description
1 RS485+ “B” side of the RS485 differential pair.
2 GP_REF
Reference lead for the RS485 rectifier GP bus. Must be connected to
the reference side of internal communication circuitry in the rectifier.
• DC Return bus (DG/Ground) in Infinity NE
• Negative 48V DC bus (BAT) in CP/EPS
3 V2SNS_BAT
Second Sense Voltage connected to appropriate non-grounded sided
of the second DC bus (BAT) to provide voltage sense.
In NE Power Systems this connection is connected to negative DC bus
of a -48V system.
4 V2SNS_DG
Second Sense Voltage connected to appropriate return/grounded
side of the second DC bus (DG) to provide voltage sense.
In NE Power Systems this connection is connected to positive DC bus
of a -48V system which is also return/DG.
5 V1SNS_DG
Primary Sense Voltage connected to appropriate return/grounded
side of the primary DC bus (DG) to provide voltage sense.
In NE Power Systems this connection is connected to negative DC bus
of a +24V system which is also return/DG.
6 V1SNS_BAT
Primary Sense Voltage connected to appropriate non-grounded sided
of the primary DC bus (BAT) to provide voltage sense.
In NE Power Systems this connection is connected to positive DC bus
of a +24V system (BAT).
7 RS485- “A” side of the RS485 differential pair.
8 DG
Reference connection to the Grounded/return side of the DC bus for
alarms.
9 V2-
Connection to the negative potential of the secondary DC bus for
secondary input power.
10 V2+
Connection to the positive potential of the secondary DC bus for
secondary input power.
11 V1-
Connection to the negative potential of the primary DC bus for the
main input power.
12 V1+
Connection to the positive potential of the primary DC bus for main
input power.
