Print PageSector-shaped solid wires SE must correspond to wire class 1, sector-shaped, solid, α = 90 °.
When making contact, the large radius must always be contacted with the conductor rail of the terminal block in order to
achieve the maximum possible contact surface.
The following processing instructions for pre-treatment of conductors also apply to the connection of aluminum wires:
Right after the stripping process, a thin, nonconductive oxide layer forms on the surface of aluminum wires. This layer must
be removed in order to establish a conductive, gas-tight connection.
For this reason, it is necessary to perform the following measures in order to guarantee a safe contact:
•
The installation and operating location must be kept free of moisture or aggressive atmosphere.
•
The stripping length specified in the technical data of the terminals must be strictly observed.
•
Use a scraper to rid the wire end of the oxidized layer. Then immediately submerge it in Vaseline (a neutral, acid-
free and alkaline-free substance) and quickly connect to the terminal block.
•
The screw in the clamping part of the screw terminal block must be closed with the maximum permissible
tightening torque of the respective modular terminal block.
•
Retighten the connection after a few days in order to ensure that it is still secure.
•
Repeat this preparation process when you need to connect a new wire or reconnect an already used wire.
