7 Electrical Installation
7.1 Connections- Unit Sizes 1x, 2x and 3x
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.
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.

7.1.1 Removal of Knockouts for Extra Cables
1.
Remove cable entry from the frequency converter (Avoiding foreign parts falling into the frequency converter when removing knockouts)
2.
Cable entry has to be supported around the knockout you intend to remove.
3.
The knockout can now be removed with a strong mandrel and a hammer.
4.
Remove burrs from the hole.
5.
Mount Cable entry on frequency converter.
