This causes themaximum input power per path to increase with the input voltage.NOTEThe overall power of the unit continues to be limited. If one input is connected to more than P(D-Cmax)/2, the maximum input power of the second input decreases accordingly. Take care that themaximum input power is not exceeded.7.4.2 ConnectionDANGERRisk of fatal injury due to electric shock (electric arc)! Wrong assignment of MPP trackers willseriously damage the inverter.Severe injury or death will result if the live connections are touched.› Make sure that each MPP tracker can be disconnected from all poles.› Observe recommended standard connection.• 1.) Standard connection - Two generators each onone MPP tracker• 2.) Unconnected inputs for unused MPP trackersEqual MPP voltages must be applied to input 1 and 2,as well as inputs 3 and 4. The MPP voltages of the twoDC paths can be different. They are tracked by separate,independently operating MPP trackers (MPP trackers Aand B). (n 1=n 2, n 3=n 4).If one of the MPP trackers (A or B) is not used, then it mustbe short-circuited, otherwise faults can occur in the self-test of the unit and the feed-in operation is not guaran-teed.The short-circuiting of an MPP tracker does not result inthe device being damaged.
