<Backup Operation>
Backup operation is possible if you use two Power Supplies of the
same model.
Even if one Power Supply fails, operation can be continued with the
other Power Supply.
Make sure that the maximum load does not exceed the capacity of
one Power Supply.
Use the S8VK-R or connect external diodes.
For backup operation with 240-W Power Supplies, use the S8VK-
R20.
• Use the following information as a guide to the diode type, dialectic
strength, and current.
DIN rail mounting
To mounting on a DIN Rail, hook portion (A) of the Block onto the rail
and press in the (B) direction.
To dismount the Block, pull down portion (C) with a flat-blade
screwdriver and pull out the Block.

Insert the solid wire or ferrule straight into the terminal block until the
end touches the terminal block.
• If a wire is difficult to connect because it is too thin, use a flat-blade
screwdriver in the same way as when connecting stranded wire.
