Revision 8
Introduction
Page 1
The Ethernet Network Card is used for monitoring and controlling purposes. The Ethernet Net-
work Card supports industry standard Modbus RS485 communication and TCP/IP protocol.
When used with an Internet connection, it can send data to an online portal from where up to 32
inverters can be monitored. It can also be used to remotely update the inverter firmware.
Capabilities
● Remote inverter firmware upgrade support by Yaskawa Solectria Solar (YSS).
● Remote diagnostics by YSS Technical Support & Service.
● Direct customer data from the Ethernet Network Card via a programmable Ethernet XML
Sunspec Data Exchange connection for customers who want to manage their own data directly.
● Pass-thru Modbus communications to a third-party gateway.

Caution:
The termination switch should always be ON if it is the last device in a daisy chain.
If the length of the cable connecting to RS485 port or Pass-through port of
the ENC is over 1000 meters, the termination switch button must be set to ON.

When the inverters are monitored via the ENC, a unique RS-485 address for each
inverter can be set up through the LCD interface.
Up to 32 inverters can be connected together in the communication network.

Install the ENC by carefully aligning
the 6-PIN connector in the upper
left-hand corner of the communication
board.
Install the (3) screws into the stand-
offs to secure the ENC in place.
Install the 3 screws and torque to 7
in-lbs using a #2 Phillips bit.

Ethernet Port
Connect the 3rd party Datalogger to the Pass-Through in the bottom left-hand corner
of the ENC using the 3-Pin Connector provided in the ENC Kit.
Connect the RS485 inverter daisy chain to the inverter communication board using
the 5-Pin Connector provided in the ENC Kit.
NOTE: The 5-Pin Connector is installed on the port on the bottom of the inverter
communication board (behind the ENC) .
The RJ45 LAN cable is inserted into
the Ethernet port of the ENC.
The LAN cable must be able to access
the Internet without port filtering behind
the firewall.
