WARNING
Warnings are indicated when mishandling this prod-
uct might result in death or serious injury to the user.

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 de-
vices. Failure to do so might cause electric shock.
Before starting transmission to the NX-CB1, be sure to
verify that it is wired properly. A wiring mistake can
cause faulty operation or a dangerous accident.
CAUTION
Use a tool such as a screwdriver to mount and remove
the DIN rail locking tab.
Do not disassemble the NX-CB1. 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 terminals. Doing so might cause electric shock.
Before wiring the NX-CB1 except network cables, be
sure to turn the power OFF. Failure to do so might cause
device failure.
Wire the NX-CB1 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 mod-
ules 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-CB1 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-CB1 within the operating ranges recom-
mended in the specifications (temperature, humidity,
voltage, vibration, shock, mounting direction, atmo-
sphere, etc.). Failure to do so might cause fire or device
failure.
When disposing of the NX-CB1, dispose of it appro-
priately as industrial waste in accordance with local
regulations.
The NX-CB1 should be handled by a specialist with ex-
pertise in electrical circuits.
If the NX-CB1 is used in a manner not specified by the
manufacturer, the protection provided by the device
may be impaired.
If the NX-CB1 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-CB1 have reinforced insulation suitable for the
maximum operating voltage of its power supply, inputs,
and outputs.
OVERVIEW
Linked by Ethernet, Network Instrumentation Modules make dis-
tributed instrumentation, high-speed communications, and easy in-
stallation all possible at the same time. The module also creates value
for customers by offering reduced environmental impact, superior
product quality, and higher productivity.
The NX-CB1 communication box is a switching hub that connects
Ethernet peer networks.
