Overheating during periodic duty

CAUTION
Periodic duty
For all operating modes, operate the external fan according to DIN EN 60034-1. Also for non-
periodic operation, the machine can be thermally overloaded. This can result in damage to
the machine.
In the case of extended non-operational periods, the fan should be in operation until the
machine has approximately reached the temperature of the coolant, see S2-operation in
DIN EN 60034‑1.
Use a suitable circuit to ensure that the external fan is appropriately operated.
4.7

Noise emission

Noise emissions
During operation, the machine's noise emission levels can exceed those permitted at the
work place. which can cause hearing damage.
Take steps to reduce noise, such as introducing covers and protective insulation or adopting
hearing protection measures, so that the machine can be operated safely within your system.
4.8 Rotational speed limit values
Permissible speed
Excessive rotational speed can lead to serious damage to the machine. This can result in
death, serious injury, or material damage.
The controller must ensure that operation at impermissible speeds is prevented. Observe the
information about the speeds on the rating plate.
