Note
Grounding the transmitter via threaded conduit connection may not provide
sufficient ground.
Note
In the explosion-proof/flameproof version, the electronics is grounded via the
transmitter housing. After installation and commissioning make sure that no
ground currents exist due to high ground potential differences in the
installation.
Transmitter housing grounding
The most effective transmitter housing grounding method is a direct
connection to earth ground with minimal (< 1 Ω) impedance. There are two
grounding screw connections provided (see Figure 4-7).

Signal cable shield grounding
Make sure the instrument cable shield is:
• trimmed close and insulated from touching the transmitter housing.
• continuously connected throughout the segment.
• connected to a good earth ground at the power supply end.
