Overheating during periodic duty

NOTICE
Non-periodic duty
In all of the operating modes, always operate the external fan according to DIN EN 60034-1.
For non-periodic operation, it is possible that the machine is 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
● Use a suitable circuit to ensure that the external fan is appropriately operated.
NOTICE
EC fan control via an input signal
The fan motor can overheat if the external EC fan is operated at low fan speeds as a result
of the setpoint signal it receives.
● Monitor the motor using the integrated temperature sensors.
● Integrate the temperature monitoring into the interlocking circuit.
4.9 Noise emissions
Noise emissions
During operation, the machine's noise emission levels can exceed those permitted at the
workplace, 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.
