Electrical Wiring
Electrical and communication wiring is achieved through terminals
located at the back of the unit. There are also two separate jumpers that
allow users to configure the detection range and end-of-line settings.
Configuring the End-of-Line
This option applies only to units configured with either Modbus or BACnet
communication.
The end-of-line jumper lets users configure the unit's end-of-line,
according to which pins are selected, as shown in the image below.
