Explanation/remedy
Because the temperatures inside the unit are too high, the
inverter reduces its power to prevent damage to the unit. Note
the technical data. Ensure that the convection cooling is not
impeded from the exterior. Do not cover the cooling fi ns.
 Provide for suffi cient cooling of the unit.
 Do not cover the cooling fi ns.
If the "priwatt" function is not activated, the potential-free
contact functions as a fault signal relay and therefore indicates
errors. However, if additional devices that are provided for the
"priwatt" function are connected to the inverter via the con-
tact, they can still start up when the inverter experiences an
error, because the contact is connected at that point in time. If
you deactivate the "priwatt" function, we recommend that you
disconnect devices from the inverter that were connected for
this function.
