6.2.1.4 Parallel connection
The power and current increase if supply modules are connected in parallel. Take into account
that the total is derated by a factor of 0.8 in doing so.
The charging capacity of the supply modules can be increased by a parallel connection only if
the power grid supply is connected to all supply modules simultaneously. Increasing the
charging capacity also requires derating the total by a factor of 0.8.
The following table shows example combinations for parallel connection.
