The main voltage and the main frequency must comply with the nomi-
nal voltage and nominal frequency indicated on the type plate.
Permissible Voltage deviation: +/- 5 %
Permissible frequency deviation: +/- 2 %
Possible power supply with:
•
fixed voltage and frequency or
•
frequency converter
The operation of NEG with frequency converters allows rotary speeds
> nominal frequency. If the NEG are operated with a frequency con-
verter, the maximum centrifugal force must not be exceeded (accord-
ing to the type plate). The compliance with the electromagnetic com-
patibility directive 2014/30/EU has to be ensured.
In the ATEX-zones 21 and 22 the frequency converter may regu-
late the frequency between 20 Hz and 50 Hz or 20 Hz and 60 Hz at a
constant torque load (linear volt-hertz-curve). Please observe the max.
frequency on the type plate. For operation with frequency converter in
ATEX-zones the PTC thermistor must be connected.
2-pole: 3000 rpm 50 Hz / 3600 rpm 60 Hz.
4-pole: 1500 rpm 50 Hz / 1800 rpm 60 Hz.
6-pole: 1000 rpm 50 Hz / 1200 rpm 60 Hz.
8-pole: 750 rpm 50 Hz / 900 rpm 60 Hz.
-20 °C to 40 °C or
-20 °C to 55 °C
The maximum ambient temperature specified on the type plate must
not be exceeded.
These values are valid for operation with an ON-period of 100 %. For
the following operation modes special requirements apply:
•
cycled operation or
•
frequency-controlled operation or
•
synchronous operation.
These must be clarified with
From housing size 170 upwards with thermistor type PTC 130 °C as
standard.
For smaller vibrators available on request as initial equipment.
If the NEA/NEG is operated in environments with potentially explo-
sive dust (zone 21/22), it is mandatory to connect the PTC-thermistor.
This regulation does not apply if the unit is not equipped with a PTC-
thermistor.
Depending on type ≤ 70 dB(A)
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-
