1 — Input LED	3 — Fault LED
2 — Output LED

CAUTION:

The V+ terminals are shunted internally together, as are the V- terminals. The same polarity terminal can be wired together from the same source to provide an additional current path in a higher power chassis. Do not connect the terminals to different sources.

Table 1 describes the LEDs on the DC power supplies.
