Note
The preassembled systems are prewired.
Warning
The electrical connection should be carried out
by qualified personnel!
Observe the local safety regulations!
Protect the cable connections and plugs against
corrosion and humidity.
Cables for single-rod electrodes or electrodes (A1, A2, B1)
1. Cut the electrode cables to the desired length + approximately
80 mm for the connections.
2. Remove 80 mm of the outer insulation.
3. Disentangle the braided screen until you reach the next part of
the insulation, and twist it to form a wire.
4. Strip the braided screen (for instance using a shrink tube), and
fit a wire end ferrule.
5. Remove the black (conductive) sheath of the insulated
electrode wire until you reach the insulation.
