User Information
This electrical equipment is an explosion-proof device designed for use in areas in which an explosive gas atmosphere will
probably occur from time to time during normal operation – as a group II category 2 device it is designed for use in Zone 1.
Thus the device is also suited for group II and category 3 applications and may be operated in Zone 2.
This device is also suited for operation in areas in which an explosive dust atmosphere will probably occur from time to time
during normal operation. As a group II and category 2 D device it may be used within Zone 21 and Zone 22.
Please note the following warnings and security information:
1. The installation and adjustment of the device must be carried out by qualified personnel in accordance with the
prescribed installation regulations taking the specified type of protection into account.
2. The device should not be operated in areas in which strong charges are generated, machines work by friction or
cutting, electrons are sprayed (e.g. in the vicinity of electrostatic paint equipment), or pneumatically transported dust
occurs.
3. This apparatus is a Protective Class II device and may only be connected to and operated at the voltage it was
designed for. Please pay attention to the polarity information.
4. If the device is damaged, it may not be operated.
5. While operating the device in business or industry facilities, the legally required precautions against accidents resulting
from the use of electrical systems and devices must be taken.
6. The device may be operated solely under the stated ambient conditions. Unfavourable ambient conditions can lead to
damage of the device and thus present a potential danger for the user.
Such unfavourable ambient conditions could include:
• moisture, dust (pay attention to the degree of protection)
• Flammable gases, vapours, solvents not covered by the type of protection
• too high ambient temperatures (>+65°C)
• Too low ambient temperatures (<-40°C)
7. Repairs may be carried out by the manufacturer or by a person appointed by the manufacturer followed by a renewed
product conformity inspection.
8. The device may only be cleaned using a damp cloth in order to avoid electrostatic charging.
9. Only cable glands as prescribed by the manufacturer may be used.
10. Make sure the device and the wiring are voltage-free upon connecting the wires in the ‘increased safety’ terminal room.
11. During operation of the device the temperature must not exceed nor fall below the prescribed range of temperatures.
Prevent unallowed radiation energy and convection in the vicinity of the device.
12. The device should be positioned in such a way that mechanical damage, e.g. due to falling parts or lateral impact is
prevented.
13. The ExII signalling light may not be operated while covered.
14. The cover, under which the luminaire is situated, is inseparably connected with the lower part of the housing. A forced
opening will destroy the device!
15. If the device is equipped with an internal programming slot in the terminal room, it may only be used outside of the
hazardous area.
16. The manufacturer cannot be made liable for damages arising from or pertaining to the connection!
17. In case of series connection of some devices it has to be considered that the max. current consumption 8A will not be
exceeded.
18. In case of direct voltage construction the prospective short circuit current external power supply must not exceed
100 A.
Should these points not be observed, the explosion protection of the device will no longer be given. The device will then
represent a danger to the life of the user and can cause the ignition of an explosive atmosphere.
