The equipment must be installed, operated, maintained and repaired by a qualified technician in compliance

with applicable laws, rules and regulations, ordinances and standards. In particular, be sure to conform to the

European Standards EN 60079-14 (Explosive atmospheres – Part 14: Electrical installations design, selection

and erection). For more information see „Verification of Intrinsic Safety" 36953-761-60 (ATEX) and „Control

Drawing" 36953-761-07 (for use in the USA and in Canada).

Installation, maintenance, cleaning and repair work may only take place with all power disconnected from the

equipment. Do not plug in or disconnect the cable in potentially explosive atmospheres.

Be sure to follow the installation, operating, maintenance and servicing instructions given in the manuals

supplied.

The equipment shall be installed in such a way that it is protected against the entry of solid foreign objects or

water capable of impairing the safety of the apparatus. Reduce the risk of mechanical damage to a minimum.

The equipment must be powered by a suitable certified/approved power supply/battery pack with intrinsically

safe circuits as described in the certificate of this equipment.

Exposure to UV radiation is not allowed! Avoid exposure to direct sunlight.

The connecting cables of the display unit must be protected against damage and stress caused by strain.

Prior to opening the equipment, disconnect the power supply or make sure that there is no potentially

explosive atmosphere or any other explosion hazard in the surrounding area!

The data cables connected to the equipment are considered as intrinsically safe circuits. The connection is

secured against accidental disconnection and may only be plugged in or disconnected when the power is

switched completely off. Check the correct function of the data transfer before you use the equipment in a

hazardous location.

If the equipment is not operating properly, unplug it immediately from the line power (mains supply) and

secure it against any further use!

10)

All metal parts must be electrically connected to the terminal for the equipotential bonding conductor (PA).

The equipment operator must to connect a lead with a gauge of at least 4 mm² (cross section) to the PA

terminal located on the side of the housing (indicated by the ground symbol). The low resistance of this

connection to the PA busbar must be checked when the system is installed at the intended place of use. Ensure

that the connection cannot be unplugged by pulling on the grounding cable. The shielding of the connecting

cables may only be used for grounding when no impermissible difference in voltage is generated and the

shielding is able to conduct the equipotential current.

11)

Avoid generating static electricity. Use only a damp cloth to wipe down the equipment. The equipment

operator shall be responsible for preventing any risks caused by static electricity.

12)

Keep chemicals and other agents, which can corrode the housing seals and cable sheaths, away from the

equipment. These agents include oil, grease, benzene, acetone and ozone. If you are not sure about the safety

of a certain substance, please contact the manufacturer.

13)

Use equipment only in the temperature ranges indicated. Avoid exposing the equipment to inadmissible

sources of heat or cold. Avoid heat build-up and ensure that the equipment has sufficient ventilation.

14)

The equipment operator is responsible for any non-Sartorius cables used.

15)

Check the EX approval marking (particularly the group for gases and temperature code) on all equipment in

the hazardous area before operation to ensure that the equipment is permitted to be operated in this area.

16)

At reasonable intervals, have your equipment installation checked for proper functioning and safety by a

trained and certified technician.

17)

If your equipment needs to be repaired, use only original spare parts supplied by the manufacturer!

18)

Any tampering with the equipment by anyone, other than repair work done by authorized Sartorius service

technicians, will result in the loss of EX conformity and in the forfeiture of all claims under the manufacturer's

warranty. Only authorized specialists may open the equipment.

19)

Modifications, including those to be carried out by Sartorius employees, may be permitted only after express

written authorization has been obtained from Sartorius.
