DANGER
Risk of fatal injury due to electric shock (electric arc)!
Wrong assignment of MPP trackers will seriously 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.
Equal MPP voltages must be applied to input 1 and 2, as well as inputs 3 and 4. The MPP voltages of the two DC
paths can be different. They are tracked by separate, independently operating MPP trackers (MPP trackers A and B).
