The inverter is supplied with pre-installed type 2 AC and DC
surge protection devices. Type 1+2 combined surge protection
devices can be ordered as accessories.
To install the type 1+2 combination surge protection devices,
the inverter must be opened. Therefore, it is best to install the
type 1+2 combined surge protection devices before mounting the
inverter and in a dry environment. The easiest way to do this is
with the inverter horizontal.
Install the combined surge protection devices before connect-
ing the inverter to the grid and solar modules. If the inverter is
already in operation, the replacement is considerably more com-
plicated for safety reasons.
All screws, spring washers and washers of the pre-installed
type 2 surge protection devices must be reused for the type 1+2
combined surge protection devices. Take precautions to ensure
that these parts cannot fall down and get lost during installation!
