Sartorius Midrics Option Y2 MIS1 Serie Manuel D'installation Et De Sécurité page 15

16. All external cables (including cables between load/weigh cells and junction box) are suitable only for
secure and protected installation and must be installed so that they cannot work loose or be damaged.
If this cannot be ensured, use cable glands, the round shape of which must have a radius of at least
one quarter of the cable diameter, but not more than 3mm, when measured across an angle of at least
75°.
17. If you plan to use other manufacturers' cables (the operator shall be liable concerning all cable connec-
tions), a suitability test must be performed. Tractive force of 10x the diameter of the cable (in mm) in N,
but applied at least at 100N for a 6-hour period, may not cause the cable to be pulled out by more than
6 mm. Be sure that the pin assignment is correct. Remove any connections not needed.
18. All openings on the equipment housing must be closed by protective caps when not in use. Do not
remove a protective cap while the equipment is under current.
19. To use non-Sartorius equipment in Zone 2, be sure they have the appropriate gas and temperature
classes; for Zone 22, make sure they do not exceed the maximum surface temperature. The outputs
must have Ex nA electrical circuits.
20. Chemicals and other agents that can corrode or otherwise damage attack the housing seals and cable
sheaths must be kept away from the equipment. These agents include oil, grease, benzene, acetone
and ozone. If you are not sure about a certain substance, please contact the manufacturer.
21. At reasonable intervals, have your equipment installation checked for proper functioning and safety by
a trained and certified technician.
22. Do not expose the equipment to extreme shocks and vibrations.
23. If an in-use dust cover is utilized, ensure that no static electricity is generated. Use only a damp cloth
to clean it.
24. If your equipment needs to be repaired, use only original replacement parts supplied by the manufac-
turer.
25. If the equipment does not operate properly, unplug it immediately from line power (mains supply) and
lock it in a safe place to prevent further use for the time being.
26. 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 for Zones 2 and 22 and in the forfeiture of all
claims under the manufacturer's warranty. Only authorized specialists may open the equipment.
27. Modifications, including those to be carried out by Sartorius employees, may be permitted only after
the express written authorization has been obtained from Sartorius.
28. The data cables connected to the equipment are considered non-incendive circuits. The connections
are secured against accidental disconnection and may only be plugged in or disconnected when the
power is switched off completely. Outputs not used must be sealed so that the IP65 protection rating
is maintained. Do not expose the indicator to voltage transients.
