2 Safety information
Work on the Sunny Boy 3800 with the
cover removed must be carried out by a
qualified electrician! Before working on
the Sunny Boy 3800 with the cover
removed, the AC and DC voltage MUST
be disconnected from the Sunny Boy
3800.
The Sunny Boy 3800 must be
disconnected from the mains grid and
precautions must be taken to prevent the
grid being reconnected. The connection to
the DC voltage must also be removed.
After isolating the AC and DC voltage you
must wait approx. 30 minutes for the capacitors in the Sunny Boy
3800 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.
The Sunny Boy 3800 is equipped with an independent mains disconnection
device, the "SMA grid guard". It ensures that the Sunny Boy 3800 complies
with the VDEW (Verband der Elektrizitätswirtschaft – German Electricity
Industry Association) regulations for the connection and parallel operation of
electrical power units to the low-voltage grid of the electricity supply company
and with DIN VDE 0126 (4.99), which forms a part of these regulations.
