5.5.2 Assembling DC Cable to Connector

All DC cables are equipped with water-proof direct plug-in connectors, which match
the DC terminals at the bottom of the inverter.
The positive and negative connectors are marked with polarity symbols
and should be equipped with correctly colored cables.
e.g. Red cable should be connected with DC positive terminal while the
blue one should be connected with the negative.
