Special conditions and instructions for safe application 1. The installation, maintenance, initial operation, removal and repair have to be controlled resp. checked by an "authorized person" for explosion protection. 2. For the electrical connection you have to take notice of the local and statutory requirements and/or the VDE 0100. 3. Take notice of the specifications on the data plate. 4. A fuse (with max. 4A) has to be connected in series to the voltage supply. 5. Protect the signal contact from voltage peaks when inductive loads are connected. 6. As soon as the device will be brought into the explosion hazardous area it has to be mounted immediately at the intended place and a cable has to be brought into the cable gland. 7. Please check if the cable gland have loosened during mounting process or transport. When it is loosened, it has to be fixed again with a torque of 3.75 Nm. 8. To secure the type of protection, the screw nut of the cable gland has to be fixed at the installation with a minimum torque of 2.7 Nm. ATTENTION! If it will be fastened too strong, the IP-protection can be affected. 9. The device has to be grounded and the ground connection of the device has to be installed in such a way that mechanical damage will be excluded. 10. The device may put into operation with built-in cap-sealing and when it is closed, only. 11. Remove the dust from the housing before you open it and make sure that no dust turbulences exist. 12. Switch off the power supply, before opening the device. (touchdangerous voltage) 13. Please check position and intactness of all gaskets before you close the device. 14. Tightening torque of distance nut M6x40: 3 ... 4 Nm and of the lid screw M6x16: 3 Nm. 15. The maximum authorised temperatures for process (bulk solids) and ambience have to be observed. 16. Take notice of the requirements of DIN EN 60079-14, DIN EN 60079-17 and DIN EN 1127-1, especially regarding the dust deposits and temperatures and follow the pertinent rules and regulations._ _ MOLLET D-74706 Osterburken Tel. +49 6291 6440-0 www.mollet.de Explosion protection information 06/21 © by MOLLET VF6-EID-05 05 M LLET Füllstandtechnik GmbH Vibro level indicator VF6. 06 VF6-EID-06 06/21 © by MOLLET Explosion protection information MOLLET D-74706 Osterburken Tel. +49 6291 6440-0 www.mollet.de
