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.

(dashed square represents the DC combiner box, recommended for installers.)
