5.4 Connecting the cooling water supply
NOTICE
Damage to bearings or the shaft
Large output masses and their centers of gravity outside the shaft extensions can lead to
resonance in operation. This can result in damage to the bearings and shaft.
Ensure that the permissible loads for the forces on the shaft extension are adhered to in
accordance with the catalog data or configuration data.
5.4
Connecting the cooling water supply
Seen from the shaft extension, connection of the water is possible from the right and from the
left.

Cooling water connection pipe
If the cooling water cannot flow freely, the machine will not be cooled properly. The machine
will overheat, which could result in material damage or even a write-off.

Filling the cooling circuit
1. Fill the cooling circuit with water until the air is completely forced out of the cooling circuit.
2. Perform a pressure check to see whether the cooling water supply is airtight. In doing so,
