These values are valid for operation with an ON-period of 100 %. Cycled or frequency-controlled operation or synchronous operation is subject to specific requirements. These must be clarified with NetterVibration on a case-by-case basis. These electric vibrators must not be used in environments with a highly explosive gas atmosphere. - Page 8 Please refer to the type plate for the technical data of your electric external vibrator.

Page 10: Transport And Storage
The unit should be stored in a clean, dry environment. If the vibrator is operated in areas with potentially explosive dust (zone 22), maintenance by NetterVibration is mandatory after a storage period of more than a year. DANGER The transport eyes are for exclusively lifting the vibrator. -

6 Installation The installation of the vibrators must only be carried out by authorised, qualified staff. IMPORTANT The staff has to work exclusively with tools suitable for the application. During installation please comply strictly with the safety regulations in chapter 2 and the accident prevention rules! Installation of the system must be performed in compliance with the local, IMPORTANT... -
Page 12: Electrical Connections
Use an additional safety device with steel cable for critical installation situa- tions, e.g. NSE. Use the wire cable clamps to set the safety cable to the shortest possible ca- DANGER ble length. The safety cable must always be tensioned! 6.2 Electrical connections The electrical installation of the vibrators must be performed only by authorised, qualified staff. - Page 13 Connection example for NEA Capacitor in cable Cable with capacitor box A suitable overload protection must be pre-connected to each vibrator. The motor protection switches must be in- terlocked with each other in pairs, so that in the event of a motor failure, the IMPORTANT power supply from both motors is inter- rupted at the same time in order not to...
- Page 14 Thermic overload protection: Standard equipment with PTC-thermistor 130°C from housing size 170 up- wards. For smaller vibrators: available on request as initial equipment. If the vibrator is operated in areas with potentially explosive dust (zone DANGER 22), it is compulsory to connect the PTC-thermistor. This regulation does not apply for units without a PTC-thermistor.

Page 15: Start-Up
7 Start-up When commissioning the vibrators, the rules and regulations of the local asso- ciations for electrical engineering (e.g. VDE) and the valid accident prevention regulations must be observed. The vibrators must always be switched on and off at the main switch. When operating the external electric vibrators with a frequency converter, com- IMPORTANT pliance with the EMC directive must be ensured. -
Page 16: Adjustment Of Unbalances
8 Adjustment of unbalances For all vibrators of the series NEA and NEG, there is the possibility of unbalance adjustment. Unless otherwise specified by you, the units were delivered with the standard setting (100 %). IMPORTANT By adjusting the unbalances, you can directly influence oscillation bandwidth, centrifugal force and current consumption. - Page 17 All centrifugal values in % can be adjusted as specified in the table. The removed lamella discs must be replaced by compensation washers (available from NetterVibration) of identical thickness and identical inner diameter. 2. The unbalance adjustment (coarse adjustment) is performed by turning one lamella disc on each side by 180°...
- Page 18 Unbalance lamella discs of the type XLs Adjustment of the unbalances is carried out according to a scale disc or the supplementary sheet in the terminal box of the unit. 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 19 Unbalance discs of the type XS The unbalance setting of the unbalance discs of the type XS is car- ried out on the scale on the fixed unbalance. The centrifugal force can be steplessly adjusted by turning the outer unbalance discs and adjusting them at the partial strokes. After ad- justing the unbalances, the nuts and screws must be tightened with the specified torque.
