Permitted Cables

Cables with the following structure can be connected to the AC and DC terminals of the
inverter:
Cu / Al
Connecting Alu- The terminals are designed for connecting single-wire, round aluminum cables. The follow-
minum Cables ing points must be taken into account when connecting aluminum cables due to the non-
conducting oxide layer of aluminum:

the connection requirements listed below.
NOTE! Take into account local specifications when configuring cable cross sec-
tions.
Carefully clean off the oxide layer of the stripped end of the cable, e.g., using a knife.
After removing the oxide layer of the cable end, rub in a neutral grease, e.g., acid-free
and alkali-free Vaseline.
Then immediately connect it to the terminal.
