  • Page 6: Safety

    Safety Safety The NEG/NEH are intended for generating circular vibrations. Intended use General applications are: loosening, conveying, sorting, compacting, sepa- rating bulk materials and reducing friction. NEG/NEH are used for empty- ing bunkers, as drives for conveyor troughs, sieves and vibrating tables. The NEG/NEH 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 Safety DANGER rules Electric shock An electric shock will result in serious injury or even death. The NEG/NEH must be free of voltage during assembly, start-up, maintenance and troubleshooting. Observe the following five safety rules: 1. Disconnect the NEG/NEH from the mains supply. 2.
  • Page 8 Safety Rotating WARNING Unbalances Risk of injury due to rotating unbalances During operation of the NEG/NEH without unbalance covers there is risk of injury due to rotating unbalances. ➢ Operate the NEG/NEH only with mounted unbalance covers. Hot surfaces CAUTION Risk of burns due to hot surfaces NEG/NEH can strongly heat up during operation.

  • Page 9: Technical Data

    The sound level is determined to a great extent by the surface upon which the NEG/NEH 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.
