Page 3: General Information
General information General information Before installing the NEA/NEG read these instructions carefully. It is the Use and basis for any action when dealing with the NEA/NEG, and may be used for storage training purposes. The instructions should be subsequently stored at the operation site. - Page 4 General information NEA/NEG from housing size 100 upwards are suitable for use in potential- ly explosive areas of the category 2D in the zone 21 and 22. In particular the standards DIN EN IEC 60079-0 and DIN EN 60079-31 (IEC 60079-31) are observed. Before using the NEA/NEG the operator must exclude the possibility that the introduction of vibrational energy poses the risk of explosion.
- Page 5 General information Notes IMPORTANT indicates actions, methods or notes that are not relative to safety, e.g. use- ful information and tips. Environmentally safe disposal indicates the obligation of environmentally safe disposal. Explosion prevention indicates information on explosion prevention. When operating the NEA/NEG in potentially explosive areas all notes, ATEX-notes marked with the Ex-symbol , must be observed.

Page 6: Safety
Safety Safety The NEA/NEG are intended for generating circular vibrations. Intended use General applications are: loosening, conveying, sorting, compacting, sepa- rating bulk materials and reducing friction. NEA/NEG are used for empty- ing bunkers, as drives for conveyor troughs, sieves and vibrating tables. The NEA/NEG are designed for installation in machines and may only be put into operation, if it has been assured that the complete machine com- plies with the regulations of the machinery directive. - Page 7 Safety High voltage DANGER Risk of electric shock due to high voltage An electric shock leads to serious injuries or even death. ➢ Observe the permissible protection class and earthing. The NEA/NEG may only be operated with the correct connection of the protective conductor. ➢...

- Page 9 Safety Hot surface WARNING Hot surface If the permissible operating conditions and the maintenance requirements are not observed or if the vibrator does not fit the application, the housing surface may become very hot. In Ex-zones there is a risk of ignition of an explosive atmos- phere due to hot surfaces.
- Page 10 Safety Falling parts WARNING Falling parts The NEA/NEG or parts of the construction can come loose due to vibra- tion. Falling parts can lead to severe personal injuries. ➢ Use only suitable fastening screws and safety washer to attach the NEA/NEG.

The sound level is determined to a great extent by the surface upon which the NEA/NEG is mounted (e.g. sheet metal). The sound level will be amplified by non-silenced sheet metal. * Higher temperatures are only possible after consultation with and written approval from the application techni- cians of NetterVibration. - Page 12 Technical data type designation Type plate for rotary speed housing sizes nominal voltage 50 and 60 current phases serial number year of manufacture / de- gree of protection insulation class power nominal frequency centrifugal force duty cycle ATEX certification type designation Type plate nominal voltage from housing...

Start-up and operation Start-up and operation Observe the safety instructions in chap. Safety, from page 6 on. Please refer to chap. Technical data, page 11 for permissible operating Permissible conditions. operating conditions • When commissioning the NEA/NEG, the rules and regulations of the Regulations local associations for electrical engineering (e.g. - Page 20 Start-up and operation Check that the cables are undamaged and laid according to the known regulations and standards. Check that all permissible operating conditions have been observed. Check that all protective measures on the system have been ob- served. Eliminate possible errors before start-up. Screw connections must be checked and, if necessary, retightened after 1 h operating time (after initial start-up) and thereafter regularly (generally monthly).
- Page 21 Start-up and operation Procedure: Switch off the NEA/NEG at the main switch, secure against uninten- tional starting and ensure that there is no voltage. Loosen both unbalance covers. Loosen the locking nuts or locking screws. Bring the unbalances to the desired setting according to the following descriptions for the various unbalance discs.

- Page 24 Start-up and operation Unbalances The centrifugal force is adjustable with the unbalance discs (lamella) type type XLs XLs. Adjustment of the unbalances is carried out according to a scale disc or the supplementary sheet in the terminal box of the NEA/NEG. By rotating the outer, adjustable unbalance disc(s) to another position, the percentage of the centrifugal force changes as shown in the illustration below.
- Page 25 Start-up and operation Example: NEG 50120 / 50 Hz has a total of 6 unbalance discs (3 discs per side: 2 fixed, 1 adjustable). If a centrifugal force of 88% is desired, the adjustable unbalance discs are rotated anticlockwise on both sides into the fourth grid position. centrifugal force 100 % centrifugal force 88 % Unbalances...
