OUTPUT
Declared power according to ISO 8528-1 (temperature 25°C, 30% relative humidity, altitude 100 m above sea level).
(*Stand-by) = maximum available power for use at variable loads for a yearly number of hours limited at 500 h. No overload is
admitted.
(**Prime power PRP) = maximum available power for use at variable loads for a yearly illimited number of hours. The average
power to be taken during a period of 24 h must not be over 80% of the PRP.
It’s admitted overload of 10% each hour every 12 h.
In an approximative way one reduces: of 1% every 100 m altitude and of 2.5% for every 5°C above 25°C.
ACOUSTIC POWER LEVEL
ATTENTION: The concrete risk due to the machine depends on the conditions in which it is used. Therefore, it is up to the end-
user and under his direct responsibility to make a correct evaluation of the same risk and to adopt specic precautions (for
instance, adopting a I.P.D. -Individual Protection Device)
Acoustic Noise Level (LwA) - Measure Unit dB(A): it stands for acoustic noise released in a certain delay of time. This is not
submitted to the distance of measurement.
Acoustic Pressure (Lp) - Measure Unit dB(A): it measures the pressure originated by sound waves emission. Its value changes
in proportion to the distance of measurement.
The here below table shows examples of acoustic pressure (Lp) at different distances from a machine with Acoustic Noise Level
(LwA) of 95 dB(A)
Lp a 1 meter = 95 dB(A) - 8 dB(A) = 87 dB(A) Lp a 7 meters = 95 dB(A) - 25 dB(A) = 70 dB(A)
Lp a 4 meters = 95 dB(A) - 20 dB(A) = 75 dB(A) Lp a 10 meters = 95 dB(A) - 28 dB(A) = 67 dB(A)
PLEASE NOTE: the symbol when with acoustic noise values, indicates that the device respects noise emission limits
according to 2000/14/CE directive.
