Installation Information

29.Required parallel system wiring length should be in accordance with the following rule, as referenced to the diagram below, to ensure approximately equal current sharing, when in static bypass mode:

(Total length of 1A + 1B) ￿ (Total length of 2A + 2B) ￿ (Total length of 3A + 3B) ￿￿(Total length of 4A + 4B)

This rule has a tolerance of approximately H10% for the combined input and output wire lengths.

If installing only two UPMs in a fully redundant system, this requirement is no longer required, as each UPM is capable of supporting the full bypass requirement. However, this would preclude future expansion.
