1. This device may be used in potentially explosive atmospheres of Zones 2 and 22. The permitted

ambient temperature range is -10°C to +40°C. The device may only be used indoors.

2. Do not use as a portable instrument.

3. Installation, operation, maintenance, and repairs should only be performed by an authorized

specialist, in accordance with applicable laws, rules and regulations, ordinances, and standards. In

particular, the EN 60079-14 standard must be taken into account. Installation, maintenance,

cleaning, and repair work may only take place with all power disconnected from the device.

4. The information on installation, operation, maintenance, and repair given in the operating

instructions supplied with the equipment must be observed.

5. Tighten the cable entry glands using a torque of 5 Nm. Tighten the cable entry gland for the mains

cable with a torque of 3 Nm only. Install the external connecting cables firmly to avoid damage

and strain. The cable connections inside the explosion-risk area must be secured against loosening.

6. All metal parts (housing, support arm, etc.) must be electrically connected to the terminal for the

equipotential bonding conductor so that any electrostatic charges can be conducted away from

the equipment. For this purpose, the equipment operator is obligated to connect a conductor with

a gauge of at least 4 mm² (cross section) to the equipotential bonding terminal (indicated by the

ground symbol) located on the back of the housing. During on-site installation, check if this

connection to the equipotential bonding conductor is of low resistance. Secure the connection

against being loosened by pulling the grounding cable.

if no metal connection

(e.g., support arm) is used. The standard indicator (which does not have a ground connection) is

wired to the equipotential bonding conductor internally.

7. Only use a damp cloth to clean the equipment. The equipment

operator assumes responsibility for preventing any risks caused by electrostatic charging.

8. When using a dust cover, avoid generating static electricity. Clean the device using a damp cloth

only.

10. The data cables connected to the appliance are classed as flammable (Ex nA) electrical circuits. The

connections are protected against involuntary disconnection and may only be connected and

disconnected when the equipment is switched off. Block unused outlets to guarantee the IP65

level of protection. Keep any transitory voltage phenomenon away from the device.

11. Use the instrument only within the specified temperature limits. Avoid exposure to inadmissible

sources of heat or cold. Heat build-up should be avoided. Ensure that the device is well ventilated.

12. During installation, take suitable steps to prevent stray electrical interference (e.g., due to

magnetic fields).

13. Ensure the device is not exposed to strong jolts or vibrations.

14. The indicator (indicator of the complete scale) should be installed so that there is only a low risk of

mechanical danger to the IP protection.

15. Accordingly, the instrument must be installed and operated in a manner that avoids exposure to

ultraviolet light (no direct sunlight).

16. The power connection must meet the regulations applicable in the country of operation. A correct

power connection must be ensured.

17. Ensure that the area is not potentially explosive when commissioning the device for the first time.

18. If cables are connected subsequently, make sure that the connections are not corroded.

19. All external cables are designed for fixed installation only and must be permanently laid.

Otherwise, use screwed connections designed in accordance with EN 60079-0 and rounded at an

angle of at least 75º and a radius equal to at least one-quarter of the diameter of the cables

without exceeding 3 mm.

20. Cables from third-party manufacturers (subject to the user’s responsibility) must be tested for

suitability: A traction strain of 10 times the diameter of the cable (in mm) in N, and at least 100 N

over 6 hours, should not stretch the cable by more than 6 mm. Follow the correct pin assignment.

Observe the wiring diagram. Remove unnecessary connections.

21. Unused openings must be sealed using suitable cover caps (dummy plugs). Do not remove while it

is carrying current.

22. When using external devices in Zone 2 explosion-risk areas, observe the gas group and

temperature class. The outputs must include the Ex nA electrical circuits.

23. Chemicals that can attack housing gaskets and cable sheathings must be kept away from the

instrument. These include oil, grease, benzine, acetone, and ozone. If you are uncertain, contact

the manufacturer.

24. The installation must be inspected for correct function and safety by a trained and qualified

person at appropriate intervals.

25. In the event of repair, use only original spare parts supplied by the manufacturer.

26. If the installation does not operate properly, disconnect it from the supply voltage immediately

and secure it against further use.

27. Any modifications to the instrument (except by persons authorized by Sartorius) will mean that it

no longer conforms to the requirements for use in Zone 2 and Zone 22 explosion-risk areas and

that all guarantee claims are null and void. Similarly, the device may only be opened by qualified

and authorized personnel.

28. Modifications (also those by Sartorius personnel) are subject to written approval.

29. The seals to the opened housing parts specified for IP65 protection must be replaced when the

instrument is repaired or serviced.
