Secure cable glands tightly.
Ensure that no drips can run into the electronic module:
• Bend the cables into a drain loop near the threaded cable gland
• Unused cable glands should be sealed with the sealing washers provided and screwed
tight.
The mains cable should be laid in such a way that it can under no circumstances come into
contact with the pipe and/or the pump and motor housing. When pumps are used with fluid
