MOUNTING AND CONNECTION
How to mount
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 remove
Push the amplifier forward.
Lift up the front part of the amplifier to remove it.
Note: 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.
How to connect
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.
Mount the main unit, the end unit and
the sensor amplifer, one by one, on
the 35mm DIN rail and set them
close to each other.
Insert the main unit side connector of
the link cable (accessory) to
side of the main unit, and insert the
quick-connection cable (accessory) to
the side of the main unit.
When inserting them, be sure to hold
the connector part.
Fit the cover to the main unit side
connector of the link cable (accessory).
Insert the quick-connection cable
(optional) or the wire-saving connec-
tor (optional) to the connector of the
sensor amplifer.
When inserting them, be sure to hold
the connector part.
Insert the end unit side connector of
the link cable to the connector of the
end unit.
When inserting them, be sure to hold
the connector part.
Mount the end plates (optional) at
both ends to hold the amplifiers
between their flat sides.
Tighten the screws to fix the end
plates.
How to dismantle
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.
