ABQ2026IQE01_A - Installation and Operation Manual
•
The inverter busbars are made of copper. We recommend using tined copper terminals, while copper
terminals are allowed. If you use aluminum cables, you must use bimetallic terminals or other
components that eliminate the galvanic couple of the joint.
•
Use the screws, washers and nuts specified by Ingeteam.
•
All torques indicated must be respected and maintained.

* To facilitate handling of the wiring, Ingeteam recommends using more than one smaller gauge cable instead of one large gauge
cable. For example, it is preferable to use two 200 mm
