Grounding
The housing should always be grounded in accordance with national and local electrical codes. Failure to
do so may impair the protection provided by the equipment. The most effective grounding method is
direct connection to ground with minimal impedance.
There is an external grounding screw located at the bottom of the housing and three internal grounding
screws located inside the housing, see
. The internal ground screws are identified
by a ground symbol:
.
Use the external ground terminal on the transmitter to ground the housing.
Figure 4-2. Grounding Terminals
Note
Grounding the transmitter using the threaded conduit connection may not provide a sufficient ground.
Make sure the connection provides a sufficiently low impedance.
Grounding - Tankbus
Signal wiring of the fieldbus segment (Tankbus) must not be grounded. Grounding one of the signal
wires may shut down the entire fieldbus segment.
