Circuit Wiring Diagrams
The following circuit wiring diagrams show how the hot, ground, and/or neutral AC
signals should be connected to the system’s power input plug:
•
Figure C-3 illustrates a single-phase 120V AC circuit connection (for ftServer 5600
and 3300 only).
•
Figure C-4 illustrates a single-phase 240V AC circuit connection.
•
Figure C-5 illustrates a split-phase 120/240V AC circuit connection.
•
Figure C-6 illustrates a three-phase 208V AC, Y-, or
∆
-source circuit connection,
phase-to-neutral.
•
Figure C-7 illustrates a three-phase 208V AC, Y-, or
∆
-source circuit connection,
phase-to-phase.
•
Figure C-8 illustrates a three-phase 380V AC, Y-, or
∆
-source circuit connection,
phase-to-neutral.
In the diagrams in this appendix, the power inputs for the ftServer system are labeled
X and Y, as shown in
Figure C-2 , 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 C-2 shows the
physical locations of the X and Y inputs on the system base.
