Figure 41. Distributed Bypass Wire Length
NOTE
Required parallel system wiring length must be equal to ensure approximately equal current sharing when in Bypass mode. For proper
operation the following must be true:
1A + 1B = 2A + 2B =
3A + 3B = 4A + 4B
NOTE
Any difference in wire length will result in decreased capacity of the UPS system while on bypass. For example, a 10% difference
between the longest and shortest wire lengths will result in a decrease in bypass capacity of 10%.
