WARNING
Warnings are indicated when mishandling this prod-
uct might result in death or serious injury to the user.
CAUTION
Cautions are indicated when mishandling this product
might result in minor injury to the user, or only physi-
cal damage to this product.
WARNING
Before removing, mounting, or wiring this device, be sure to
turn off the power to the device and any connected devices.
Failure to do so might cause electric shock.
Before starting transmission to the NX-SWA, be sure to verify
that it is wired properly. A wiring mistake can cause faulty op-
eration or a dangerous accident.
CAUTION
Use a tool such as a screwdriver to mount and remove the DIN
rail locking tab.
CAUTION
Do not disassemble the NX-SWA. Doing so might cause device
failure.
Do not block ventilation holes. Doing so might cause fire or
device failure.
Do not allow wire clippings, metal shavings or water to enter the
controller case. They might cause fire or device failure.
Do not touch electrically charged parts such as the power ter-
minals. Doing so might cause electric shock.
Before wiring the NX-SWA except network cables, be sure to
turn the power OFF. Failure to do so might cause device failure.
Wire the NX-SWA properly using the specified types of wire
and following recognized installation methods. Failure to do so
might cause electric shock, fire or device failure.
Make sure that there are no loose connections. Failure to do so
might cause overheating or device failure.
Ensure the total power consumption of all linked modules does
not exceed 70 W. Failure to do so might cause fire or faulty
operation.
Supply power to all linked modules from the same power
source. Using two or more power sources can cause fire or
faulty operation.
Do not use unused terminals on the NX-SWA as relay terminals.
Doing so might cause electric shock, fire or device failure.
Firmly tighten the terminal screws to the torque listed in the
specifications. Insufficient tightening of terminal screws might
cause electric shock or fire.
If there is a risk of a power surge caused by lightning, use a
surge absorber (surge protector). Failure to do so may cause
fire or device failure.
Use the NX-SWA within the operating ranges recommended in
the specifications (temperature, humidity, voltage, vibration,
shock, mounting direction, atmosphere, etc.). Failure to do so
might cause fire or device failure.
When disposing of the NX-SWA, dispose of it appropriately as
industrial waste in accordance with local regulations.
The NX-SWA should be handled by a specialist with expertise in
electrical circuits.
If the NX-SWA is used in a manner not specified by the
manufacturer, the protection provided by the device may be
impaired.
If the NX-SWA is dirty, wipe it with a soft dry cloth. Never use an
organic solvent like benzene or thinner.
Make sure that devices and equipment connected to the NX-
SWA have reinforced insulation suitable for the maximum oper-
ating voltage of its power supply, inputs, and outputs.
OVERVIEW
The NX-SWA Industrial Switching Hub is a 4-port switching hub. It has
connectors on the left and right sides for expansion, allowing it to be used
as a 6-port switching hub when connected to a communication adapter.
In addition, if multiple NX-SWA units are linked together by the side
connectors, a cascade connection is possible without the use of cables.
Two models are available: the NX-SWAR for ring communication using
an Ethernet trunk line, and the NX-SWAN, which is not compatible with
ring communication.
As an optional extra, models compatible with fiber-optic cable are available.
