PR bus leads should be connected to like pin#’s
on redundant arrays when equipped with optional
current share transformer. Twist wires and daisy
chain rather than a star connect. Keep length as
short as possible.***

To disable output(s) apply +5 Vdc between pins
10 and 20 in the polarity indicated
* Removable jumpers in J4 are factory installed for local sensing. For remote sensing and redundant
parallel arrays as illustrated above the +Sense pins should be tied to the same point on the +Out
power
bus; the -Sense pins should be tied to the same point the -Out power bus.
** There should be one master module, this is realized by choosing one module to be the master and
shorting the SC to –S on the other module. Units configured from the factory as paralled will already
have this configured. This should be verified by direct inspection prior to system integration.
*** There should be one master module, this is realized by choosing one module to be the master and
shorting the SC to –S on the other module. This is done by installing a 0
Ω resistor in the space
provided on the lugmate / plugmate.
