Table 7. Recommendedcablesandfusesforthe(4)UPSwithSPMwiringdiagrams.
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 +/- 10% for the combined input and output wire
lengths. If installing only two UPS modules, this requirement is no longer required, as each
UPS is capable of supporting the full bypass requirement. However, this would preclude future
expansion.
