Page 19: Electrical Connections
ELECTRICAL CONNECTIONS VTX3 4.1 General notes The separate intrinsically safe signal circuits are electrically connected in the terminal compartment of the signal converter. The circuits are designed in protection type "intrinsically safe" and galvanically isolated from ground (test voltage ≥ 500 V The intrinsically safe flow sensor circuits are connected in the connection boxes on the wall bracket and on the flow sensor. -
Page 20: Inputs / Outputs
ELECTRICAL CONNECTIONS VTX3 4.3 Inputs / Outputs The terminal assignment is described in the manual. The signal circuits of the vortex flowmeters may only be connected to certified intrinsically safe slave units or circuits. For more information refer to chapter "Electrical data". The current output, the current input and the binary output are designed for connection to a certified, intrinsically safe circuit in protection type "intrinsic safety Ex ia IIC or Ex ib IIC". - Page 21 ELECTRICAL CONNECTIONS VTX3 For remote versions with pressure sensor, the connection of the flow sensor can either be made via the PA connection in the signal converter terminal compartment or via the external PA connection.

ELECTRICAL CONNECTIONS VTX3 4.5 Flow 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 50 m / 164 ft). • Before connecting or loosening the equipotential bonding cable, ensure there are no differences in potential. -
Page 23: Operation
OPERATION VTX3 5.1 Start-up Start-up is only permitted when the measuring device: • is correctly installed in the system and connected. • has been checked for the proper state with regard to its installation and connection requirements. The operator of the system has to check prior to start-up, if the start-up was in compliance with the national regulations for checks. -
