installation and wiring read and follow
the detailed instructions given in this

8.1.2 Cable Splicing
To connect the motor cable with a cable extension
you should connect the cable ends with a splicing kit.
It is very important that the cable joints are fully
sealed otherwise moisture could cause a short
circuit. This will damage the pump system.
For more information about connecting cable
ends with a splicing kit see the “submersible cable
splicing” manual in the package of the splicing kit.
a
CAUTION – Cable splice failures are
a common source of errors. Check the
splice for proper connections.
CAUTION – Bad cable splicing can
damage the controller and/or the pump.
Such damage is excluded from the
warranty.
