TO SET THE CENTER INVERTERS FOR THE NETWORK

On the front of the user interface PCB, using the Modbus Termination switches:
1. Place the Low switch in the OFF position.
2. Place the Line switch in the OFF position.
3. Place the High switch in the OFF position.

TO SET NETWORK BIASING

Biasing sets the voltage levels on the data lines of an inactive or idle network. At
least one device on the network must provide biasing. On shorter networks with
fewer installed devices, biasing may only be needed on the device furthest away from
the master. Longer networks that are terminated on both ends may require two
devices to have their biasing enabled.
To Set the Jumpers to Use the Inverter's Built-in Biasing
On the front of the user interface PCB, using the Modbus Termination switches:
1. Place the Low switch in the ON position.
2. Place the Line switch in the OFF position.
3. Place the High switch in the ON position.

TO TERMINATE THE NETWORK AND ENABLE BIASING

As an alternative, an end inverter on the network can require both termination and
biasing to be enabled. On the front of the user interface PCB, set the following
switches to configure the inverter for both settings.
1. Place the Low switch in the ON position.
2. Place the Line switch in the ON position.
3. Place the High switch in the ON position.

Setting the Modbus Address

A Modbus network containing slave devices requires a unique address for each slave.
These unique addresses allow the master device to identify and communicate with
each slave. The Modbus network administrator must assign a unique Modbus address
to each AE inverter.
The Modbus Address switches are located on the user interface PCB in the card
cage in the data monitoring compartment.
