Note on conductor pretreatment
The following measures are required for durable and reliable contacting of
the aluminum conductor: the stripped end of the aluminum conductor must
be separated from the oxide layer using a blade, and immediately dipped
in non-acid and non-alkali Vaseline. The pretreatment must be repeated
when connecting the conductors anew.
