Connecting Backup Devices
Observe the following precautions when using a backup device, such
as one from OMRON's S8T Series.
• When a backup device is connected to the S8V-CP output, backup
current is supplied to the other output through the internal circuit,
and at the same time, internal components may be degraded or
damaged. When you use a backup device together, be sure to
connect it to the power input side of the S8V-CP.
• If you connect the backup device to the S8V-CP input terminal, the
backup time will be shorter than usual due to the consumption of
internal power. Always confirm the backup time when using a
backup device.
DIN rail mounting
S8V-CP0424/S8V-CP0424S
To mount the Product to a DIN rail, pull down the rail stopper until you
hear it clicks open, hook portion (A) of the Product onto the DIN rail,
press the Product in direction (B), and then push up the rail stopper to
lock the Product in place.
S8V-CP0824
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.
Connecting Wires to the Push-In Plus Terminal
Block
Part Names of the Terminal Block
Connecting Wires with Ferrules and Solid Wires
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 wires.
Connecting Stranded Wires
Use the following procedure to connect the wires to the terminal block.
1.
Hold a flat-blade screwdriver at an angle and insert it into the
release hole. The angle should be between 10° to 15°. If the flat-
blade screwdriver is inserted correctly, you will feel the spring in
the release hole.
2.
With the flat-blade screwdriver still inserted into the release hole,
insert the wire into the terminal hole until it strikes the terminal
block. Always twist stranded wires together before inserting them.
3.
Remove the flat-blade screwdriver from the release hole.
Checking Connections
• After the insertion, pull gently on the wire to make sure that it will
not come off and the wire is securely fastened to the terminal block
• If you use the recommended ferrule, part of the conductor may be
visible after the ferrule is inserted into the terminal block, but the
Product insulation distance will still be satisfied.
Removing Wires from the Push-In Plus Terminal
Block
Use the following procedure to remove wires from the terminal block.
The same method is used to remove stranded wires, solid wires, and
ferrules.
1.
Hold a flat-blade screwdriver at an angle and insert it into the
release hole.
2.
With the flat-blade screwdriver still inserted into the release hole,
remove the wire from the terminal insertion hole.
3.
Remove the flat-blade screwdriver from the release hole.
