On the Interface board are located two LED's:
•
Green LED showing the status of the Interface:
- Fast Blinking: 2 times/sec = Interface is Master (1
- Slow Blinking: 1 times/sec = Interface is Slave ( 2
•
Red LED
On the Master cabinet the following ports of the customer interface board are active:
•
The Input ports (X3)
•
The Output ports (X2)
•
The Interlock function (X1)
On the Salve cabinet(s) following ports of the customer interface board are active:
•
The Input ports (X3)
•

JD1 / RS232 PC / Laptop Interface
The Computer Interface JD1 located on the distribution part is an intelligent RS 232 serial port that allows the
UPS system to be connected to a computer. The connector JD1 is a standard D-Type, 9-pin, female.
It is used to download system event log and to make firmware upgrades.
5.1.4
USB PC / Laptop Interface
The Computer Interface USB has the same function as the RS 232 serial port JD1. Use either USB or RS232 but
not both at the same time.
5.1.5
JR2 / RS232 Interface for Multidrop
The Computer Interface JR2 (RJ 45 connector) located on the distribution part is the Multidrop connection which
is needed for multi-cabinet configurations. To enable the Multidrop communication between cabinets it is necessary
to set JP2 jumper correctly on the customer interface board as shown in the table here below.
Customer Interface Board, PCB NW22085D (with ROM76-12) or NW22085E or later versions
First unit (Master)
Middle Unit (Slave)
Last Unit (Slave)
Note: on the (older) versions NW22085B/C without ROM76-12 make a bridge between X3-11 & X3-12.

Optional feature: Configuration of the External Output Breaker
An External Output Breaker can be connected to each UPS cabinet. Pin 9 and 10 of the phoenix terminal X3 is the
input of the UPS for the auxiliary contact of the External Output Breaker. To enable this function it is necessary to
set JP8 and JP1-JP5 jumpers correctly on the customer interface board and parallel board of each unit as shown
in the two tables here below.
