Operation

Maximum Number of Blocks That Can Be Linked
Basic Blocks can be linked using Bus Line Connectors.

N+1 Redundant Systems
To ensure stable operation when there is a failure in one of the
Blocks, use within the derating curve for N+1 redundant systems.
Multi-output Power Supply
Up to 4 Basic Blocks with different output voltage specifications
can be linked.
Selecting Bus Line Connectors
Select Bus Line Connectors according to the linking method as
follows:
• Using parallel operation:
S8T-BUS01 (DC line connected)
The S8T-BUS01 Bus Line Connector is equipped with a selector
to prevent erroneous connection of Blocks with different output
voltage specifications. Slide the selector to the output voltage for
parallel operation.

Mounting and Removing Bus Line Connectors
Pay attention to the following points to maintain electrical charac-
teristics.
• Do not insert/remove the Connectors more than 20 times.
• Do not touch the Connector terminals.
• To remove the Connectors, insert a flat-bladed screwdriver alter-
nately at both ends.
Wiring Linked Blocks
When linking Blocks together, wire input lines to one Block only,
otherwise inputs may be shorted internally resulting in damage to
the Block.
Do not wire inputs to more than one Block.
L N L
Do not cross-wire Blocks or wire between a Block and another
device. If the rated current is exceeded, Bus Line Connectors may
be damaged.
Do not use cross-wire Blocks.

When Basic Blocks are linked together, it is necessary to wire the
GR terminal of only one Block, not all the Blocks.
Series Operation and ± Output
Using 2 Basic Blocks enables series operation and the use of
± output. An external diode is not required for S8TS-06024
S8TS-03012 models but is required for S8TS-02505
