Monitoring Port Cable (Phoenix Connector)

Appearance and Structure

Figure 9-30 shows the structure of the monitoring port cable and the Phoenix connector.

Figure 9-30 Structure of a monitoring port cable and Phoenix connector

The monitoring ports provide two input lines, which can be used to monitor two types of devices that support output voltage monitoring. DI1+ is the input high level of line 1 and DI1- is the input low level of line 1. Similarly, DI2+ is the input high level of line 2 and DI2- is the input low level of line 2.


The monitoring port must be used with the Phoenix connector (included in the installation accessory package) and the monitoring port cable (purchased separately). The monitoring port cable must be a conductive cable. Table 9-16 lists the specifications of the monitoring port cable.

Minimum Conductor Cross-Sectional Area

Maximum Conductor Cross-Sectional Area

0.08 mm2 or 28 AWG

1.5 mm2 or 16 AWG


One end of the monitoring port cable is used with the Phoenix connector and connected to the monitoring port of the S5720I-SI. The other end needs to be made onsite. You can make the power cables according to site requirements and connect the cables to external devices to be monitored.
