3.7 Single-Phase and Three Phase Multiple Box System Configurations

Three Phase System:
Refer to Figure 3-4 for the output power connections for a 3-phase power system. For
connections to a single power source disregard the connections to the Auxiliary power sources
shown in Figure 3-4.
All multi-source systems must be interconnected using the system Interface cable. All of the
respective outputs from the power sources must be connected at an external terminal block as
shown in Figure 3-4. The connections to the Output Sense terminal block of the Master power
sources should be connected to the point where the voltage is to be regulated. If the sense lines
are not connected the programmed output voltage will be regulated and the output of the Master
Power source.
For all multi-source power systems only the Master power source can control and report the
measured system output.
Single Phase System:
Refer to Figure 3-4. If the Single Phase mode is programmed the Phase B and C output from all
power sources must be connected to Phase A. The Master power source will still monitor the
total output current from all of the power sources for each phase.
The units must all be connected with the system interface cable.
NOTE: The three Output Neutral connections from each source should be tied together. The
Output Neutrals are connected internally but in the 1-phase mode because of the increased
current they must be also connected external to the power source. In addition, the power
source's also programmed to single phase. ( Menu 3 Ultility1  Voltage/Current control
