4.3.2 Multiple HHS-1X5K/10K/15K/20K in parallel
Up to 3 pcs HHS-1X5K/10K/15K/20K can be connected in parallel. The power conductor of the
combined HHS-1X5K/10K/15K/20K output shall be according to the total current rated.
Consider using a distribution box when combining positive and negative output from
multiple HHS-1X5K/10K/15K/20K as illustrated below. Choose proper conductor / cable in a way
that the current during normal or fault condition (fault current) do not lead to excessive heating of
the material or fire hazard.
