7 Start-up and operation

Observe the safety instructions in Ch. Safety, from page 6 on.

Please refer to Ch. Technical data, page 11 for permissible operating con-

ditions.

 When commissioning the NEA/NEG, the rules and regulations of the

local associations for electrical engineering (e.g. VDE) and the valid

accident prevention regulations must be observed.

 The NEA/NEG must always be switched on and off at the main switch.

 When operating the NEA/NEG with a frequency converter, compliance

with the EMC directive must be ensured.

 If the speed is controlled with a frequency converter, the maximum

centrifugal force (according to the type plate) must not be exceeded.

NEA/NEG must be adapted to your application by adjusting the unbal-

ances. You can directly influence the vibration amplitude, centrifugal

force and current consumption.

 The NEA/NEG must not be operated without the covers for the unbal-

ances. The rotating unbalances cause a risk of injury.

 On initial start-up, the current consumption must be measured individ-

ually in all three phases and must correspond to the specifications on

the type plate.

 The terminal box cover must never be opened in the presence of volt-

age.

Special regulations for operation in an potentially explosive at-

mosphere:

 In ATEX-zones 21 and 22, the frequency converter may control the

frequency between 20 Hz and 50 Hz or 20 Hz and 60 Hz at constant

torque (linear Volt-Hertz curve). Observe maximum frequency on the

type plate.

 For operation with frequency converter in ATEX-zones the PTC ther-

mistor must be connected.

 The terminal box cover must never be opened in a potentially explosive

atmosphere.

 NEA/NEG may only be operated in atmospheres that do not damage

the material of the vibrators.

Carry out the following measures before start-up:

1. Check that the NEA/NEG have been mounted correctly and are in per-

fect condition.

2. Check that the NEA/NEG have been properly connected and earthed.
