three series-connected units. These figures allow other configurations, e.g., five parallel-con-
nected units or two series connected units, etc. to be easily deduced. Figure 2-12 shows the
connections for a typical 3 X 2 (two parallel branches each consisting of three series-connected
units) configuration, as well as simplified diagrams showing required arrangements for 2 X 2.
CAUTION: FOR PARALLEL CONFIGURATIONS, REMOVE LINKS BETWEEN (COM S)
AND (COM OUT) TERMINALS OF ALL SLAVES TO PREVENT DAMAGE TO
THE UNIT AND MAINTAIN SYSTEM ACCURACY.
The following connections are required.
• Power cables
• Sense connections (either local or remote)
• All interconnection cables and terminations required for parallel, series, 2 X 2 or 3 X 2
configurations are supplied in the applicable Interconnection Kit (see Table 1-5 for part
number).
2.8.1 MULTIPLE UNIT SOURCE POWER
Multiple units must all be connected to the same a-c input power source.
CAUTION: CONNECTING MULTIPLE UNITS TO DIFFERENT A-C INPUT SOURCES MAY
DAMAGE THE BOP POWER SUPPLIES AND/OR THE LOAD.
2.8.2 MULTIPLE UNIT PROTECTION
For multiple unit configurations it is necessary to configure the protection so that a fault will shut
down all the interconnected power supplies. Figure 2-8 is a simplified diagram showing typical
interconnections for master/slave configurations.
