POWER CONNECTIONS BETWEEN ASSEMBLIES
AND OPTIONAL HEATSINKS
To minimize the offset voltage between assembly grounds,
the resistance of the ground power cabling should be
inversely proportional to the number of power sections
that connect through the ground cabling. In other words,
if the master assembly has five power sections and the
slave assembly has four power sections, then the resis-
tance of the master ground cabling should be 4/5 of the
slave ground cable resistance. Figure 11 shows how to
make a ground cable that is 4/5 the resistance of a refer-
ence ground cable.

to Minimize the Offset Voltage Between Assembly Grounds
