Electrical safety
Motor protection relay
Motor protection devices must be set to the nominal motor current. A relay set too low
prevents optimum use of the motor. A relay set too high does not guarantee full thermal
protection.
Thermistor protection (TF contact)
For motors that are frequently started and stopped, intermittently operated, use a high
switching frequency or power controller, it is essential to use a motor protection relay and
thermistor protection. This is to avoid prematurely switching the motor protection relay or
overheating of the motor winding in these operational conditions.
Sound level
The A-weighted emission sound pressure level L
pA
at workstations does not exceed 70dB(A).
Note
The sound pressure level applies to typical pallets made of wood or plastic.
Pallets made of other materials might increase the sound level.
Note
Factors like the state of the machine, filling degrees of products, state of the
bearings, geometry and surface of the building, external noise sources also
influence the noise level. The user should carry out additional measurements for
workplace noise assessments after the machine is in full operation.
Personal safety
For your own safety use personal protective equipment.
Always wear proper personal protective equipment when working with, on or near the
machine.
