For aluminum connections, follow these steps to prepare the wires, one wire at a time.
a) Remove the appropriate amount of wire insulation
b) Use a wire brush to remove the oxidation layer from the aluminum conductors.
c) Immediately apply neutral dielectric grease (such as Noalox) and connect the cable to the terminal.
If the connection is not made within 30 seconds of applying the grease, repeat this process as an oxidized
layer may have formed on top of the conductor. An oxidized layer is a poor conductor which could lead to
thermal issues, production loss, or damage to the inverter.
