CAUTION: On the DC power supply, 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 10 on page 38 describes the LEDs on the DC power supply modules.
