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%.
