4.4 Cooling water inlet temperature (plug-on shaft)
Cooling water intake temperature
The maximum cooling water intake temperature is 25 °C.
NOTICE
Condensation for an excessively low cooling water intake temperature
If the temperature difference between cooling water and ambient temperature is greater than
5 K, this may result in condensation forming in the machine. This results in material damage.
● Make sure that the condensation can drain away freely.
● Adopt appropriate measures to achieve the required intake temperature of the cooling
● Alternatively, dry the ambient air.

Noise emissions

Noise emissions
During operation, the machine's noise emission levels can exceed those permitted at the
workplace, which can cause hearing damage.
● Ensure that nobody is in the area of increased noise emissions during machine operation.
● Take steps to reduce noise so that the machine can be operated safely within your system.
