Connection of the converter-side deionized water circuit
The converter-side deionized water circuit is connected to the collecting pipes of the
adjacent Cabinet Module using permanently installed pipes:
● When option W34 is ordered, the fixed pipe connections are routed downward to the
right-hand side of the Heat Exchanger Module.
The Heat Exchanger Module can therefore be installed at the left-hand end of the drive
lineup and connected to the deionized water circuit on the converter side.
● When option W36 is ordered, the fixed pipe connections are routed downward to the left-
hand side of the Heat Exchanger Module.
As a consequence, the Heat Exchanger Module can be installed at the right-hand end of
the drive lineup and connected to the deionized water circuit on the converter side.
● For a transport unit (option Y11), these connections to the deionized water circuit on the
converter side are already installed at the factory; when supplied separately, after the
cabinet units have been mechanically connected, then they must be connected up on the
plant side.
Establishing the connections
Connection with the collecting pipes of the adjacent Cabinet Modules:
1. For this connection, use "COMBI-GRIP" pipe couplings.
These are pipe couplings that are used to connect pipes manufactured out of different
materials (plastic and steel).
It is important that the pipe couplings are used with the correct alignment, otherwise the
connections will not be watertight.
2. Ensure that the support rings are inserted in the connection locations of the collection
pipe. Ensure that the support rings are flush with the collection pipe.
3. Insert the pipe couplings into the collecting pipes of the left-hand or right-hand cabinet
unit.
4. Move the cabinet units together to the final installation dimension, also see Chapter
"Connecting the cooling circuit collecting pipes (Page 58)".
5. Align the individual cabinet units so that they are in a perfectly straight line and at the
same height. This may require the use of leveling measures, such as the insertion of
spacer plates. Ensure that the water pipes precisely line up axially with one another:
