UPS Installation Plan and Unpacking
• External parallel system wiring length should be in accordance with
equal current sharing when in bypass mode.

Figure 11. 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:
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%.
