These safety instructions apply to the installation, operation, maintenance and repair of the
equipment
1.
The equipment may be used in the potentially explosive areas of Zone 2 and 22. In Zone 22,
the device is only for use in the presence of non-conductive dusts. The permissible ambient
temperature is –10°C ... +40°C. The equipment must be used indoors.
2.
The terminal 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, be sure to conform to the 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.
Be 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 prote ctive 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, drive-on ramp, bench, etc.) must be electrically connected to the
terminal for 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 mm
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 equipotential 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 connect 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. Ensure that the equipment is properly
ventilated.
9.
Ensure proper installation to avoid vagrant current (e.g., magnetic fields).
10.
Make sure that the equipment is installed an d operated without being exposed to impermissible UV
radiation (avoid direct exposure to sunlight).
11.
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 vali d in your country must be observed.
Be sure that the correct power supply cable is used.
12.
Prior to initial operation, make sure that there is no potentially explosive atmosphere or any other
explosion hazard in the surrounding area.
13.
Avoid generatin g 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.
