These configurations have the same restrictions as explained in 6.2 - Alternate Grounding Config-

uration, Wye-Connected Service, except for the wye input. The UPS input and bypass must be fed 

from the same source. The load must be strictly 3-wire. And the GFI time delay should be set to at 

least 0.2 seconds to prevent tripping during transfer or retransfer operations.

Failure to properly set the ground fault interrupters could cause loss of power to the critical 

load.
