Cable routes
If it is possible, install the input, output and control cables in separate trays.
If the control cables must go over power cables, align them at an angle of 90 degrees.
Make sure that the control cables are installed at least 20 cm (8 inches) from the DC
input and AC output cables. Do not put any cables behind the inverter.
Ground and bond metal cable trays to each other. Aluminum trays improve potential
equalization.
Route all cables so that they do not prevent access to the DC switch (if present).
1. DC input cables
2. Control cables
3. AC output cable
4. Separate PE cable, if applicable
