1. Push the signal and supply voltage cables through cable entries (1) and (2) and
(where applicable) push the Ethernet cable through the cable entry (3). To ensure
tight sealing, do not remove the sealing ring from the cable entry.
2. Connect the protective conductor to terminal V-.
3. Ground the transmitter housing with ground terminal (4). Make sure that terminal
V- and the transmitter housing are grounded separately from one another.
4. Connect the signal and supply voltage cables to the transmitter via screw terminals,
5. 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.
6. Firmly tighten the cable glands.

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.
7.3.5
Closing the housing cover
1. Close the housing cover.
2. Tighten the 4 fixing screws on the housing cover. Screw in the screws
without
using
any lubricant (grease). If lubricant is used, the housing degree of protection can be
compromised due to poor housing sealing.
