Installation
M70A_262 support Cu stranded wire, Cu flexible conducor, Al stranded wire and
aluminum solid (include sector wire).
Cu stranded
• Cu:
The Cu flexible wire need stamp with terminal, for the other model wiring with
bear wire is available.
• Al:
The oxide layer at the end of the terminal must be removed when
connecting the aluminum wire. After removing the oxide layer,
we recommended cost the neutral fat or acid-free, alkali-free
vaseline on the end of the conductor and connect the conductor
immediately. It's necessary to treat the oxide layer when reconnect
the wire.
* The sector wiring direction is shown as right figure.
If not following the above pretreatment, the contact resistance will
-
increase significantly which will lead to the excessive temperature
rise, even catch fire.
