AVS parallel connection
AVS series connection
ACS parallel connection
To work properly, user needs to group the modules connected in parallel or series. To work properly, the
modules must be connected in parallel or series. Only modules of the same model can be connected in series
or in parallel. When a certain module will be included in the group, there are restrictions in place to protect
the user and system. Please refer to Section 5.1.5.2 for Module Grouping configuration and Section 6 for
Module Grouping details.
4.5.3.1 AVS Parallel Connection
All modules connected in parallel should:
be grouped as one using ISOCOMM WebTool.
have the same module configuration.
have positive terminals connected in parallel.
have negative terminals connected in parallel.
have “ISHARE” signals (Module’s J2 pin 10) star connected.
have “A_RTN” signals (Module’s J2 pin 4) star connected.
have “REMOTE_SENSE_+” signals star connected and connected to the desired point of regulation.
have “REMOTE_SENSE_-” signals star connected and connected to the desired point of regulation.
have “SYS_RTN” signals (Module’s J1 pin 8) star connected
have “0-10VEXT_VPROG” signals (Module’s J1 pin 1) star connected if system will be operating using 0-
10VEXT_VPROG.
have “0-5VEXT_VPROG” signal (Module’s J1 pin 2) signals star connected if system will be operating
using 0-5VEXT_VPROG.
Warning! - Module’s J2 signals and output voltage are isolated from module’s J1 signals.
4.5.3.1.1 AVS Parallel Connection Protection
Each individual module in a group will protect independently and will protect as stated in Section 4.5.1.
4.5.3.2 AVS Series Connection
All modules connected in series should:
be group as one using ISOCOMM WebTool
have the same module configuration.
have output terminals connected in series.
have each module’s “REMOTE_SENSE_+” connected to its own positive output terminal.
have each module’s “REMOTE_SENSE_-” connected to its own negative output terminal.
