ELECTRICAL CONNECTIONS OPTISWIRL 4070 4.4 Grounding and equipotential bonding CAUTION! Equipotential bonding Equipotential bonding Equipotential bonding Equipotential bonding Vortex signal converters must be included in on-site equipotential bonding acc. to EN 60079-14! They are connected to the PA terminals. In the case of compact meters and measuring units with flange connections, the sensor is conductively connected to the pipeline. -
Page 16: Sensor Circuits (Remote Version Only)
ELECTRICAL CONNECTIONS OPTISWIRL 4070 4.5 Sensor circuits (remote version only) Observe the following points when connecting the flow sensor to the signal converter: • Use only the supplied connecting cable (max. length 15 m / 49 ft). • Before connecting or loosening the equipotential bonding cable, ensure there are no differences in potential. -
Page 17: Operation
OPERATION OPTISWIRL 4070 5.1 Start-up Start-up may only commence when the vortex flowmeter: • is correctly installed in the system and connected. • has been checked for the proper state with regard to its installation and connection requirements. The user of the system must have it checked before start-up in compliance with the national regulations for checks before startup. -
