For outdoor use, ensure that an appropriate cable is used. If the
cable is very stiff, an intermediate terminal should be used in
order to change from a stiff to a more flexible cable before
entering the inverter. For some cables it might be sufficient to
remove the hard outer mantle of the part of the cable inside
the inverter enclosure. This is to protect the PCB-mounted
RJ-45 Ethernet ports from excessive strain, which could lead
to damage or connection issues.
