DANGER
Les voltages alternatifs et continus seront toujours présents aux points de
contact CA et CC de l’onduleur à moins que les disjoncteurs du réseau public
et que les alimentations des piles PV ne soient débranchés.
Step 1: Installing the Modbus Cable for TCP/IP
A. Route an Ethernet cable from a network port in the facility that has been approved by
the network administrator, through the data monitoring gland plate on the right side
of the inverter, using the appropriate water-tight conduit connections.
The data monitoring gland plate is a at piece of metal covering the side entry
port to the inverter’s data monitoring compartment. Remove the gland plate and
cut a hole in the desired location to allow access for the cable. Replace the gland
plate.
B. Connect the Modbus Ethernet cable to the Ethernet port on the Comm X PCB. The
Comm X PCB is located in the Data Monitoring Section in the right upper cabinet of
the inverter. See Figure 5-1 for the location of the Ethernet port.
5.5 Modbus TCP/IP Network Configuration Process
Step 2: Assigning the IP Address and Port ID
A. Contact the facility’s IT Network Administrator (or person with similar responsibili-
ties) to assign an IP Address to each inverter.
B. The Modbus master will need to communicate through Port 502.
For advanced users, a static IP address can be assigned. Contact PV Powered Technical
Support for assistance.
5.6 Networking Using the Modbus RS-485 Option
The following steps are required to set up a Modbus RS-485 network for your PV
Powered commercial inverter. The rst part of the installation can be completed by a
PV installer or electrician that does not have working knowledge of a Modbus network.
These steps are:
A. Field installation process (to be performed on-site)
The rst three steps can be completed by a PV installer that does not have working
knowledge of a Modbus network:
• Installing the Modbus network wiring.
• Conguring end-of-line termination and network biasing.
• Setting the Modbus address for each slave inverter.
Note: The contractor responsible for network programming will need to provide the
slave addresses prior to setting the Modbus address for each slave inverter.
