Figure 6–12: Parallel Connection with Remote Sensing
CAUTION
Make sure the connection between –V terminals is reliable to prevent disconnection during
operation. Disconnection may cause damage to the power supply.
NOTE
With local sensing, it is important to minimize wire length to decrease wire resistance. In addition,
the positive and negative wire lengths should be as close as possible to each other to achieve
better current balance between power supplies.
6.9.3 Advanced Parallel System Acknowledge
The acknowledge system prevents unintended changes of advanced paralleling assembled
systems.
Following initial system assembly, the new assembled system has to be “acknowledged”. Any
further change in the system configuration has to be “acknowledged” (A change in the system can
be done by removing slave units, adding additional slave units or changing the role of a unit from
slave to master).
The acknowledge process is performed on the master unit. The acknowledge process is available
via the Front Panel or communications.
