①
②
Fit the rear part of the mounting section of the unit
on a 35mm width DIN rail.
Press down the rear part of the mounting section of
the unit on the 35mm width DIN rail and fit the front
part of the mounting section to the DIN rail.
How to mount
Take care that if the front part is lifted without pushing the
amplifier forward, the hook on the rear portion of the mounting section is likely to break.
Note:
How to remove

Be sure that the power supply is off while adding or removing the units and
mounting or removing the link cable (SC-GU1-CC02), the quick-connection
cable and the wire-saving connector (CN-701).
When the amplifiers are mounted in cascade, mount the optional end plates (MS-DIN-E)
at the both ends of the amplifiers to hold them between the flat sides of the plates.
Up to maximum 16 sensor amplifers can be connected in cascade between
the main unit (SC-GU1-485) and the end unit(SC-GU1-EU).
In case two different models of sensor amplifer are mounted in cascade, be
sure to mount identical models together.
Max. 31 nodes connection is possible with this communication unit.
For the cautions of the sensor amplifers, refer to the instruction manual
enclosed with the amplifiers.

Pressing the projection at the top of
each connector, pull out the connector.
Remove the main unit, the end unit
and the sensor amplifers.
Note: Take care that if the connector is pulled out without pressing the projection, the projection may
break. Do not use a link cable, quick-connection cable or wire-saving connector whose
projection has broken.
Furthermore, do not pull by holding the cable, as this can cause a cable-break.

●The link cable (SC-GU1-CC02) can be shortened with the
desired length. However, the cable cannot be extended.
HOW TO CHANGE THE LENGTH OF LINK CABLE (SC-GU1-CC02)

Procedure
①Use 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.
②
③
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 φ1.2mm or less.
④Insert 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.

⑤Place the head of a flathead screwdriver
underneath the operating lever (white)
through the releasing slot, and lift the
screwdriver head.
If you hear a snap, the operating lever
(white) is returned and the wire is fixed.

⑦
Slightly pull the wire to ensure that the wire
is not loose.
Also, check that they are not in contact with
each other.
Fit the cover to the connector.

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
connected to each other, max. 31 nodes can be
connected. Wire them as shown in the right figure.
The wire process length should be 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.).
