Electrical Circuit and Wiring Information B-3

NOTE

As shown in Figure B-2, the power inputs for the ftServer

system are labeled X and Y in the diagrams in this

appendix to eliminate any ambiguities in the

nomenclature. For single-phase applications, the X input

is connected to the L (Line) hot input, and the Y input is

connected to the N (Neutral) input. However, for

split-phase or three-phase applications, the X and Y

inputs are connected to L1, L2, or L3 (separate lines).

Therefore, for split-phase or three-phase applications,

both X and Y can be electrically hot with respect to the

system base (earth reference ground). Figure B-2

illustrates the physical locations of the X and Y inputs on

the system base.
