Only one ground conductor is required ineach conduit.Raceway applications:* Positive and negative battery cables must be run side by side in the raceway in an alternating pattern (+ - + - + - + -).* There must be a ground cable running in the raceway with the battery cables.NOTE If a 4-pole Automatic Transfer Switch (ATS) is used to connect the UPS to a generator or alternative input source, it mayinterrupt the UPS input neutral during its transition between sources. For the 9395 UPS:The ATS transition must be open in both directions. The "break" time for the contacts must be at least 50 ms. This allows the UPS tooperate properly, however it is important to evaluate whether the critical load will function properly as its neutral reference is rapidly(50 ms) switched. Note also that if the UPS load is on bypass, an ATS switchover with interruption of the neutral, will interrupt thereturn current path and cause a loss of all phase-to-neutral loads.If an overlapping neutral or make-before-break ATS switch is used, the neutrals must overlap for a minimum of 50 ms during thetransition.UPS Installation Plan and Unpacking
