1. The system's internal temperature controls the rotating speed of the fan module. Therefore,
this standard value might be exceeded if the maximum load continues under high-
temperature environment or if a failure occurs in the system.
2. Sound pressure level (LA) changes from 66 dB or 75 dB, according to the ambient
temperature, drive configuration, and operating status. Maximum volume can reach 79 dB
during maintenance procedure for a failed ENC or power supply.
3. Acoustic power level (LwA) measured by the ISO 7779 standard is 7.2 B. This value changes
from 7.2 B to 8.1 B, according to the ambient temperature, drive configuration, and operating
status.
