3 How to Install

3.3 Electrical Installation

NB!
Cables General
All cabling must comply with national and local regulations on cable cross-sections and ambient temperature. Copper (75°C) conductors
are recommended.
3
Aluminium Conductors
Terminals can accept aluminium conductors but the conductor surface has to be clean and the oxidation must be removed and sealed by neutral acid-
free Vaseline grease before the conductor is connected.
Furthermore the terminal screw must be retightened after two days due to softness of the aluminium. It is crucial to keep the connection a gas tight
joint, otherwise the aluminium surface will oxidize again.
