CONNECTION WITH UPPER COMMUNICATION CABLE
Make sure that the power is off while wiring.
Be sure to use the specified communication cable.
The communication distance should be within the specification.
When the main units (SC-GU1-485) are connect-
ed to each other, max. 31 nodes can be connect-
ed. Wire them as shown in the right figure.
The wire process length should be 7mm.
7mm
Do not plate the wire connected to the terminal
block connector with solder etc., since the
connected wire may come off by loosening screws.
The tightening torque of the screws for wire
fixing should be 0.5N m or less.
The screws of the flange part should be tighten
as well so that the terminal block connector
does not come off from the main body. The
tightening torque should be 0.5N m or less
For the communication cable, use a shielded
twist-pair cable. Furthermore, the shield should
be connect to the frame ground (F.G.).
<Recommended>
KPEV-S 0.5SQ 1P manufactured by Sumitomo Electric
Industries, Ltd.
Note that the frame ground (F.G.) terminal has
not been connected to inside the unit.
Be sure that the DIP switch/termination select
on the main unit in the termination node is set
to ON side, and the DIP switch/termination
select on the main units other than the
termination node is set to OFF side.
Connect a termination resistance (100 ) in
the termination node.
Note: The termination resistance is fit in the main unit.
Be sure that the DIP switch/termination select on the main unit in the termination node is set
to ON side, and the DIP switch/termination select on the main units other than the termination
node is set to OFF side.

HOW TO CHANGE THE LENGTH OF LINK CABLE (SC-GU1-CC02)
The link cable (SC-GU1-CC02) can be shortened with the
desired length. However, the cable cannot be extended.
Procedure
Use a flathead screwdriver (Blade width: 2mm or less) to push
the operating lever (white) located at the wire inlet on the main
unit side connector of the link cable until it is locked.
Cut the link cable at the desired length.
Process the core length to 7 to 8mm in accordance with 'STRIP GAUGE' indicated
on the side of the connector, and twist the core
several times.
When using shielded wires, be sure to twist
the wire to a diameter of
I
nsert the wire to the bottom of the wire inlet.
Check that the shielded part of the wire is
properly inserted into the wire inlet as well
as that the core end has passed through
the wire connection area as shown in the
right figure.

CAUTIONS
This product has been developed / produced for industrial use only.
Make sure that the power supply is off while wiring and adding the units.
Take care that wrong wiring will damage the sensor.
Verify that the supply voltage variation is within the rating including the
sensor amplifer.
In case noise generating equipment (switching regulator, inverter motor,
etc.) is used in the vicinity of this product, connect the frame ground (F.G.)
terminal of the equipment to an actual ground.
Do not use during the initial transient time (1 sec.) after the power supply is switched on.
This sensor is suitable for indoor use only.
Do not use this sensor in places having excessive vapor, dust, etc.
Take care that the product does not come in contact with water, oil, grease,
organic solvents, such as, thinner, etc., or strong acid and alkaline.
This sensor cannot be used in an environment containing inflammable or explosive gases.
Never disassemble or modify the sensor.
