INSTALLATION OPTISWIRL 2100 3.1 Mounting Mounting and setup must be carried out according to the applicable installation standards (e.g. IEC 60079-14) by qualified personnel trained in explosion protection. The information given in the manual and these instructions must always be observed.
INSTALLATION OPTISWIRL 2100 3.2 Special conditions Electrostatics If the installation takes place in hazardous areas of group IIC, the instructions for electrostatics must be observed. For further information refer to Electrostatic charge on page 22. Thermal and electrical data Observe the maximum ambient and product temperatures and electrical data.
ELECTRICAL CONNECTIONS OPTISWIRL 2100 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.
ELECTRICAL CONNECTIONS OPTISWIRL 2100 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".

ELECTRICAL CONNECTIONS OPTISWIRL 2100 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. Figure 4-2: Ground connection of the remote version...
ELECTRICAL CONNECTIONS OPTISWIRL 2100 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.
OPERATION OPTISWIRL 2100 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.
SERVICE OPTISWIRL 2100 6.1 Maintenance Maintenance work of a safety-relevant nature within the meaning of explosion protection may only be carried out by the manufacturer, his authorised representative or under the supervision of authorised inspectors. ® Treat cover threads as necessary with the lubricating paint UNIMOLY C220 For systems in hazardous areas, regular tests are required in order to maintain the proper condition.
