5.3 Cables

The cables for the level switches and the pump(s) can be led into
the pit in different ways. Often the cables are led into the pit
through a cable entry in the side of the pit. If the pit is equipped
with a vent pipe, the pipe can be used as cable entry.
When dismantling or assembling the pump, make
sure not to pinch or damage the cables.
Caution
After mounting the pump and cables, the cables
must be suspended in such manner that any
stress are relieved from the cables.
