WARNING
Hearing damage
Hearing damage may occur if the motor exceeds a sound pressure level of 70 dB (A) due to
the type of mounting or pulse frequency.
• Reduce the sound pressure level by implementing sound damping and/or soundproofing
measures.
When operated in the speed range 0 to rated speed, 1FT2 motors can reach the following

The motors are certified for a wide range of installation and operating conditions. These
conditions such as rigid or vibration-isolated foundation design influence noise emission,
sometimes significantly.
