Caution! Overvoltage
Check the system design using the "Sunny
Design" design tool (
www.SMA.de ) or by
calling the Sunny Boy Hotline.
Overvoltages may lead to the destruction
of the Sunny Boy SB 1100LV.
Warning! High voltage!
Work on the Sunny Boy with the cover removed must be carried out by a
qualified electrician. High voltages are present in the device. Before
working on the Sunny Boy with the cover removed, the AC and DC
voltages must be disconnected from the Sunny Boy and the capacitors
must be discharged.
The Sunny Boy must be disconnected from the mains grid and precautions
must be taken to prevent the grid being reconnected. In addition, the
connections to the PV generator must be disconnected.
After isolating the AC and DC voltage, you must wait approx. 30 minutes
for the capacitors in the Sunny Boy to discharge. Only then is it safe to
open the unit by removing the cover. You must also make sure that no
voltage is present in the device.
Caution! Electrostatic charge!
When working on the Sunny Boy SB 1100LV and handling the
components, remember to observe all ESD safety regulations. Electronic
components are susceptible to electrostatic charge. Discharge any
electrostatic charge by touching the grounded enclosure before handling
any electronic component.
