2.6 Electrical data
The 24 VDC power supply circuit, the RS485 interface and the earth potential (housing) are
galvanically conneted within the electromagnetic flowmeter.
For both circuits the 24 VDC power supply and the RS485 interface a safety separation from
hazardous voltage is required (SELV / PELV).
The equipment may only be connected by means of the permanently connected cable.

3.1 Installation
Installation 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
Installation and Operation Instructions and the Supplementary Installation and Operation
Instructions must always be observed.
Electromagnetic flowmeters must be installed in such a way that
•There is no danger from mechanical impact effects.
•There are no external forces affecting the equipment.
•The equipment is accessible for any visual inspections that are necessary, and can be viewed
from all sides.
•The data plate is clearly visible.
•The equipment is protected against UV-light.
CAUTION!
The manufacturer is not liable for any damage resulting from improper use or use other than the
intended purpose. This applies in particular to hazards due to insufficient corrosion resistance
and suitability of the materials in contact with the product.
DANGER!
The optional connector at the connection side of the cable shall be connected outside the
hazardous area.

4.1 General notes
The circuits are not galvanically isolated from ground (housing).
The connecting cable is in conformity with the applicable installation standard EN 60079-14. The
temperature rating of the cable is equal to or better than -40 ... +90 °C.
•The connecting cable must be fixed and laid so it is sufficiently protected against damage.
•The shield must be carefully insulated against each core and against ground (test voltage t
500 V
eff
) at the connection side.
4.2 Power supply
The electromagnetic flowmeter does require a power supply unit complying with standards for a
safety separation from hazardous voltage (SELV / PELV) (e. g. IEC 60950-1).
The power supply may only be connected by means of the permanently connected cable.
4.3 Inputs/outputs
The RS485 interface assignment is described in the Standard Installation and Operation
Instructions.
The RS485 circuit may only be connected by means of the permanently connected cable to a
standard RS485 interface complying with the requirements for a safety sparation from
hazardous voltage (SELV).
4.4 Grounding and equipotential bonding
The electromagnetic flowmeter shall be connected to the equipotential bonding of the hazardous
area by using the external ground connection facility. The position of the external ground
connection facility is next to the cable entry.
For connecting the bonding conductor to the housing a ring cable lug suitable for a M5 screw
shall be used. Connection to the equipotential bonding of the hazardous area provides a safe
grounding of the equipment.
INFORMATION!
The power supply circuit is connected to ground inside the equipment. To avoid circulating
current the power supply circuit shall not be connected to ground at the connection side.
INFORMATION!
The RS485 circuit is connected to ground inside the equipment. To avoid circulating current the
RS485 circuit shall not be connected to ground at the connection side.
DANGER!
A missing connection to the equipotential bonding system may cause the danger of electrostatic
charging of the metallic parts and the risk of an ignition of a present explosive atmosphere.

5.1 Start-up
Start-up is only permitted when the electromagnetic flowmeter:
•is correctly installed in the system and connected.
•has been checked for the proper state with regard to its installation and connection
requirements.
•is free of explosive atmosphere inside the measuring tube
The user of the system must check before start-up in compliance with the national regulations
for checks before start-up.
5.2 Operation
Electromagnetic flowmeters must be operated in such a way that they remain within the
maximum and minimum permissible temperatures and pressures and the rated electrical
values.
Electromagnetic flowmeters may only be operated if the equipment parts necessary for safety
are effective in the long run, and are not rendered inoperable during operation.
WARNING!
Ignition risks caused by impact must be avoided.

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.
To maintain proper condition, regular inspections are required for systems in hazardous areas.
The following checks are recommended:
•Checking the housing, the cable entries and the process connections for corrosion and/or
damage.
•Checking the measuring unit and the process connections for leakage.
•Including the flowmeter in the regular pressure test of the process line.
6.2 Dismantling
In order to prevent injury or material damage when replacing the sensor, always observe the
following points:
•Before dismantling, ensure that all the cables leading to the flowmeter are de-energised
themselves and to the ground potential of the explosive area.
•All the relevant process pipes or containers must be depressurised before dismounting the
flowmeter.
•If the process pipes or the container contain products that are harmful to the environment or
to health, implement the appropriate safety measures before dismantling the flowmeter.
•Replace all the seals when reinstalling the device in the process pipe or container.
CAUTION!
Maintenance measures 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.
WARNING!
Dismantling must be carried out by qualified personnel trained in explosion protection.
