Battery Conductor Sizing
: Eaton strongly recommends using the specified DC conductor size and quantity shown above for
optimum system performance and battery run time.
Battery Cable Routing Requirements
Conduit applications:
* Each conduit must have a Positive, Negative, and Ground conductor.
* There must be an equal number of positive and negative conductors in a single conduit. Only one ground conductor is required in
each 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 may
interrupt the UPS input neutral during its transition between sources. For the 9395P 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 to
operate 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 the
return 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 the
transition.
