4.10 CAN Bus Interfaces (X6, X7)
The unit can be controlled and monitored via the 10-pin CAN bus
connector X6, if the SBS is installed in a power supply cabinet with
PSM control unit.
The CAN bus connector X7 is always required for communication
with the INV when operated with SBS. In this case, only the end of
the bus on the INV must have a terminating resistor connected; a bus
terminating resistor is integrated in the SBS! (See Figure 1.)
4.11 DIL Switch
An 8-pin DIL switch is located below the LCD. All settings of/ changes
to the DIL switch are only activated at mains operation, i.e. when the
operating status is "on". Also press the Reset button to take over the
settings of the DIL switches. It is counted from the left S3.1 to the
right S3.8, switches that are pushed in at the bottom signify "open"!
The setting of the switches is shown on the display as a check
whenever a change is made; 0 = open; 1 = closed.
Switches S3.1, S3.2 and S3.3: Number of parallel INVs in the
system
The settings must be the same on all INVs and the SBS!
Example: 4 INVs are in the system, at least 3 INVs should run,
i.e. 1 INV is redundant: S3.1=0; S3.2=1; S3.3=1; S3.7=0; S3.8=1
