Electrical Connection
The terminal box is screwed to the electrode by means of a self-locking fixing nut.
Before establishing the electrical connection you can turn the terminal box by max. +/– 180 ° to the
desired position (cable outlet).
A flexible multi-core control cable, min. conductor size 0.75 mm
2
can be used for wiring.
