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-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.
CAUTION
Do not disassemble the NX-CB2. 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-CB2 except network cables, be sure to turn the
power OFF. Failure to do so might cause device failure.
Wire the NX-CB2 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-CB2 as relay terminals.
Doing so might cause electric shock, fire or device failure.
Firmly tighten the terminal screws to the torque listed in the speci-
fications. 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-CB2 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-CB2, dispose of it appropriately as indus-
trial waste in accordance with local regulations.
The NX-CB2 should be handled by a specialist with expertise in elec-
trical circuits.
If the NX-CB2 is used in a manner not specified by the manufacturer,
the protection provided by the device may be impaired.
If the NX-CB2 is dirty, wipe it with a soft dry cloth. Never use an or-
ganic solvent like benzene or thinner.
Make sure that devices and equipment connected to the NX-CB2
have reinforced insulation suitable for the maximum operating volt-
age of its power supply, inputs, and outputs.
OVERVIEW
Linked by Ethernet, Network Instrumentation Modules make distributed
instrumentation, high-speed communications, and easy installation 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-CB2 communication box is a switching hub that connects
Ethernet peer networks.
As an optional extra, models compatible with fiber-optic cable are
available.
