In the following the expression „device“ refers to the indicator type CAIXS2. The expression „equipment“ refers
to the indicator type CAIXS2 and to the other connected devices.
1) Install the equipment 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“
66015-751-60 (ATEX) and „Control Drawing“ 66015-751-07 (for use in the USA and in Canada).
2) Be sure to follow the installation, operating, maintenance and servicing instructions for the connected devices
given in the manuals supplied.
3) The device 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.
4) The equipment must be powered by a suitable certified/approved power supply or battery pack with intrinsically
safe circuits as described in the certificate of this equipment.
5) Exposure to UV radiation is not allowed!
6) 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!
7) The data cables connected to the equipment are considered as intrinsically safe circuits. The connections are
secured against accidental disconnections and may only be plugged in or disconnected when the power is
switched completely off.
8) Output not used must be safeguarded by appropriate sealing cap (maybe in the scope of delivery) so that the
IP6x protection rating is maintained.
9) The injection of any external voltage must be avoided by suitable installation of the connected cables!
10) Check the correct function of the data transfer before you use the equipment in a hazardous location.
11) If the equipment does not operate properly, unplug it immediately from line power (mains supply)! If the device
shows visible damages, unplug it and make sure that it will not be used anymore.
12) All metal parts must be electrically connected to the terminal for the equipotential bonding conductor (PA). The
equipment operator is obligated 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. The low resistance of this connection to the PA busbar must be
checked when the system is installed at the intended place of use. The shielding of the connecting cables may
only be used for grounding when no impermissible difference in voltage is generated and, if necessary, the
shielding is able to conduct the equipotential current.
13) 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.
14) 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.
15) Use equipment only in the temperature ranges indicated. Avoid exposing the equipment to heat.
16) The equipment operator is responsible for any non-Sartorius cables used.
17) Check the EX approval marking (particularly the group for gases/dusts and temperature class/code) on all
equipment in the hazardous area before operation to ensure that this approved equipment is permitted to be
operated in this area.
18) At reasonable intervals, have your equipment installation checked for proper functioning and safety by a trained
and certified technician.
19) If your equipment needs to be repaired, use only original spare parts supplied by the manufacturer!
20) 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 by working to Sartorius rule.
21) Modifications, including those to be carried out by Sartorius employees, may be permitted only after the express
written authorization has been obtained from Sartorius.
22) If the housing has been opened, close the housing with a tightening torque of 1 Nm.
23) If the housing has been opened again after the first field wiring, the gasket must be replaced!
