The installation and adjustment of the device must be carried out by qualified personnel in accordance with theprescribed 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 orcutting, electrons are sprayed (e.g. in the vicini- ty of electrostatic paint equipment), or pneumatically transporteddust occurs.3. The device may only be connected to and operated at the voltage it was designed for. Please pay attention to thepolarity information.4. Take care not to damage the housing.5. While operating the device in business or industry facilities, the legally required precautions against accidents resultingfrom 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 todamage 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 (> +40°C / +55°C)• Too low ambient temperatures (< -55°C)7. During operation of the device the temperature must not exceed nor fall below the prescribed range of ambienttemperatures.8. Repairs may be carried out by the manufacturer or by a person appointed by the manufacturer followed by a renewedproduct conformity inspection.9. Adjustments in the compression-proof compartment of the housing must be made by the manufacturer or byauthorized technical specialists only. The necessary opening and closing of the flameproof enclosure must carriedthrough as follows:• Remove voltage from the device.• Observe the mandatory waiting time before opening the unit (see sign on unit).• Unfasten and unscrew the special locking screw on the side of the housing• Unscrew the upper part of the housing by turning it counter-clockwise• Perform the maintenance while the device is open• Take care to keep the thread slightly greased• Close the device by repeating the steps in reverse order10. Only cable glands as prescribed by the manufacturer may be used. Use only suitable tools for installing the cableglands. The cable connection is suited only for permanent cables. Cable diameter Ø 5.5 to 13.0 mm.11. Make sure the device and the wiring are voltage-free upon connecting the wires in the ‘increased safety’ terminalroom.12. Only terminals as prescribed by the manufacturer may be used.13. Electrical installations inspection and maintenance: The equipment does not contain any parts that neededmaintaining. The specifications of EN 60079-17 concerning the regular checking of explosion protection are to becomplied with.14.
