Before connecting aluminum wires to terminals:
1. Remove oxide from the exposed wires with emery paper or a
steel wire brush
2. Clean dust with a cloth and Isopropyl alcohol (IPA)
3. Coat wires with a designated antioxidant aluminum wire
grease immediately after cleaning
CAUTION!Connection of oxidize aluminum wires may result
in resistance and high temperatures at contact points.
Improper execution of the following procedure may cause
damage to the unit.
