10.12.43 Connecting a Monitoring Cable to a PD800 Coulometer
Prerequisites
An RS485 monitoring cable has been prepared.
You are familiar with the functions of all ports on the CCU collector by referring to
10.12.2 Port Description for the CCU Collector
You are familiar with the functions of all ports on the ECC collector by referring to
10.12.3 Port Description for the ECC Collector
Context
Before the PDU8000 configured with the PD800 coulometer is delivered, the wiring terminal
block in the PDU8000 has connected to the RS485 port on the rear of the PD800 coulometer.
You only need to connect the monitoring cable to the wiring terminal block in the PDU8000.
Locate the RS485 port on the wiring terminal block by using either of the following methods:
Obtain the number of the RS485 port on the wiring terminal block from the conceptual
diagram.
Locate the RS485 port on the rear of the coulometer and the other end of the cable. The
port to which the other end connects is the RS485 port.
This topic describes how to connect a monitoring cable to the PD800 coulometer in a 380 V
UPS output PDU8000.
Procedure
Step 1
View the PDU8000 conceptual diagram and determine that the RS485+ port on the wiring
terminal block is numbered 7 and the RS485- port is numbered 8, as shown in
Figure 10-73

Step 2
Connect the cord end terminal of the RS485 monitoring cable to the RS485 port in the
PDU8000.
lists the mapping between the wiring terminals in the RS485 port and
the colors of core wires in the cord end terminal.
