3 Safety Instructions
3.1 Handling of the Sunny Mini Central
All work on and in the Sunny Mini Central must be carried out by a
qualified electrician. The electrician must be approved by the local energy
supplier.
Open and close the Sunny Mini Central only as described in section 10
"Opening and Closing the Sunny Mini Central" (Page 58) and follow the
safety instructions listed there.
The Sunny Mini Central weighs approximately 63 kg. Two people must
carry the unit or a suitable transport trolley must be used. Safety boots
must be worn.
The temperature of individual parts of the housing and of components
inside the Sunny Mini Central can reach more than 60 °C. Touching these
parts could result in severe burns.
Once the handle of the Electronic Solar Switch has been pulled out, the
Sunny Mini Central provides protection rating IP21. Thus it is no longer
protected against water seepage and foreign objects.
Check the system design using the Sunny Design program ( www.SMA.de )
or by calling the Sunny Boy Serviceline before installing the Sunny Mini
Central. Overvoltages lead to the destruction of the Sunny Mini Central,
thereby voiding all warranty claims.
Avoid contact with the PV modules when they are running, as a minimal
displacement current could flow and cause a secondary accident due to
shock. Therefore, maintenance work may only be performed on the solar
generator when it is disconnected. Disconnecting the Sunny Mini Central
from the grid is not sufficient.
In addition, touchable conducting parts such as the framework of the PV
generator should be grounded.
