7. Grounding
•
Warning: All flowmeters must be properly grounded to avoid personnel shock hazard.
•
The ground conductor should not transmit any interference voltages, therefore do not ground
any other electrical devices together with this conductor.
Separate primary head IFS 6000 F with terminal box
•
A functional ground FE must always be connected.
•
Signal converters with a field power supply of > 125 mA / > 60 V:
Because of the higher field current from the signal converter, a PE protective conductor must
be connected to the IFS 6000 F primary head, see grounding diagrams.
