7.2.2
Connecting the signal and supply voltage cables
The measuring device does not have an internal circuit breaker. For this reason,
assign the measuring device a switch or power-circuit breaker that allows the power
supply line to be easily disconnected from the mains.
The signal can be transmitted using analog technology via the analog output and using
digital technology via Ethernet (Modbus protocol). The connection to the "Teqwave Viewer"
operating tool is also established via the Ethernet interface. For information on
establishing the connection to the "Teqwave Viewer", see the → 34.

DANGER
Serious or fatal injury from electric shock
‣
Ground terminal V- and the sensor housing separately from one another because
terminal V- is connected to the sensor housing.
1. Connect the protective conductor to terminal V-.
2. Ground the transmitter housing. Make sure that terminal V- and the transmitter
housing are grounded separately from one another.
3. Connect the signal and supply voltage cables to the transmitter via screw terminals,
4. For transmission via Modbus protocol or connection to the Teqwave Viewer, connect
the Ethernet cable to the Ethernet port of the transmitter and the Ethernet port of
the computer or network. For information on establishing the connection to the
"Teqwave Viewer", see the → 34.
7.2.3
Ensuring potential equalization
The measuring device must be included in the potential equalization. The transmitter and
sensor are connected to the same potential via the connecting cable. This potential must
be current-free.

Connecting the measuring device: transmitter with
stainless steel housing
