Sartorius Midrics Option Y2 Instalación E Indicaciones De Seguridad página 14

These safety instructions apply to the installation, operation, maintenance and repair
of the equipment
1. The equipment may be used zone 2 and 22 hazardous areas. In zone 22, the device is approved for
use only in the presence of non-conductive dusts. The permissible ambient temperature is –10°C to
+40°C (14°F to 104°F). The equipment must be used indoors.
2. The indicator may not be used as a portable device.
3. Installation, operation, maintenance and repair of the equipment may only be performed by an
authorized technician and in compliance with applicable laws, rules and regulations, ordinances and
standards. In particular, make sure all work performed conforms to European Standards EN 60079-14
(Electrical apparatus for use in potentially explosive gas atmospheres) and EN 50281-1-2 (Apparatus
for use in the presence of combustible dusts). Installation, operation, maintenance and repair of the
equipment may only be performed when the equipment is completely disconnected from the power
supply.
4. Make sure to follow the installation, operating, maintenance and servicing instructions given in the
manuals supplied.
5. The cable glands must be fastened using a torque of 5 Nm. Use only 3 Nm to fasten the power cable.
The external connecting cables must be installed in a protective tube and secured to prevent damage
and stress caused by strain. The cable connections in the hazardous area must be secured to prevent
them from working loose.
6. All metal parts (housing, column, etc.) must be electrically connected to the equipotential bonding
conductor (PA) so that any electrostatic charges can be conducted away from the equipment. The
equipment operator is obligated to connect a lead with a gauge of at least 4 mmÇ (cross section) to the
PA terminal (marked by the grounding symbol) located at the rear 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 the shielding is able to conduct the potentially occurring equipo-
tential current.
7. Before opening the equipment, completely turn off the power or make sure that no potentially explosive
atmosphere is present in the area or any other explosion hazard in the surrounding area. Never con-
nect or disconnect cables while the power is on in a hazardous area!
8. Use equipment only in the temperature ranges indicated. Avoid exposing the equipment to impermissible
sources of heat or cold. Avoid heat build-up. Make sure the equipment is properly ventilated.
9. Ensure proper installation to avoid vagrant current (e.g., magnetic fields).
10. Install the indicator (or the display and control unit supplied with the complete scale) in such a way that
mechanical hazard to the IP protection is kept to a minimum.
11. Make sure that the equipment is installed and operated without being exposed to impermissible UV
radiation (avoid direct exposure to sunlight).
12. Ensure that the voltage rating or power supply is identical to your local power rating. When connecting
the equipment to the power supply, the laws valid in your country must be observed. Be sure that the
correct power supply cable is used.
13. Prior to initial operation, make sure that there is no potentially explosive atmosphere or any other
explosion hazard in the surrounding area.
14. 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.
15. If cables are connected at a later date, make sure the connectors are not corroded.
