Figure 3-9. 93PM External Parallel 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 = 2A = 3A = 4A

1B = 2B = 3B = 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%.
