7.3 Removing components for maintenance
NOTICE
Malfunction due to changing the connection configuration
The pumping station connections are pre-configured at the factory. If the control lines on the connec-
tor are mixed up, this causes the pumping station to malfunction or fail.
► When removing components, note their original layout for subsequent re-assembly.
► Make a note of the accessories configuration and important setting values from the DCU before
disassembly of the pumping station or components.
Customer maintenance on pumping station components may require removal from the pumping station
frame.
