CAUTION
If an open circuit voltage of more than 100 V is supplied to the connected solar
module, the controller will be destroyed. When selecting the solar module, it
is important to bear in mind that the open circuit voltage should never exceed
100 V over the entire working temperature range.
When using solar modules with a maximum open circuit voltage of between
75 and 100 V (over the entire temperature range), all installation steps must be
carried in accordance with protection class II.
