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.

Connecting the cooling water supply
The inlet and outlet sockets for the cooling water supply are situated on the non-drive end in
the bearing shield area. On the end shield, two hexagonal couplers with

" female thread are
each screwed onto a washer.
1. Only use valves, fittings and cooling water pipes made of non-corrosive, high-grade steel
in the cooling system.
2. Make sure that the cooling water meets the required cooling water specification, see section
headed "Cooling Water Quality" (Page 25).
3. Make sure that the appropriate volume of cooling water is available, see Rating Plate
Flow rate
Pressure drop

1.6 bar
4. Hold the hexagon head steady with an open-ended spanner while you screw in the water
pipes.
5. Screw the cooling water pipes into the female thread. You can connect the inlet and outlet
as required.
NOTICE
Securing the hexagonal couplers
The hexagonal couples are connected directly to the water pipes inside the machine. The
application of excessive torque during screwing in can damage the pipe system.
Hold the couplers steady with an open-ended spanner when you screw in the water pipes.
6. Ensure that the maximum permissible operating pressure does not exceed 6 bar.
