TSV300 AC voltage transducer Installation Guide

Qualified personnel must install the device. It shouldn't be installed outside directly.
The installation process involves mounting the device, connecting it to the RS-485 bus, attaching inputs, supplying
power, and configuring it through the master.
Warning! Power off before wiring.
Ensure that wires are securely attached to terminals and tightened. Improper wiring or configuration can cause
permanent damage to TSV300 or connected equipment

According to modbus.org, the two-Wire MODBUS definition is: 
“A MODBUS solution over a serial line should implement a “Two-Wire” electrical interface in accordance with 
EIA/TIA-485 standard. On such a “Two-Wire” topology, at any time one driver only has the right for transmitting. 
In fact, a third conductor must also interconnect all the devices of the bus - the common (ground).”

It is highly advisable to use a daisy-chain (linear) topology along with UTP/FTP cables when connecting multiple
sensors. To ensure the interface functions correctly, terminators (120-ohm resistors) must be installed at both
ends of the bus. The device comes equipped with a built-in 120-ohm resistor, and for bus termination, the
terminals "485-" and "Term" should be shortened.
