In order to ensure drip protection and strain relief on the cable connections, only cables
with a suitable outer diameter may be used (for the required cross-section, please see
the table "Cable cross-sections").
Secure cable glands tightly.
Ensure that no drips can run into the electronic module:
ƒ
Bend the cables into a drain loop near the threaded cable gland
ƒ
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 temperatures above 90°C, a mains cable with suitable thermal resistance
must be used.
