WARNING
Before removing, mounting, or wiring the NX-S11/12/21,
be sure to turn off the module and all connected devices.
Failure to do so might cause electric shock.
Before starting transmission to the NX-S11/12/21, 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 or remove the
DIN rail locking tab. Otherwise, you might be injured.
Do not disassemble the NX-S11/12/21. 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 live parts such as the power terminals.
Doing so might cause electric shock.
Before wiring the NX-S11/12/21, be sure to turn the
power OFF. Failure to do so might cause device failure.
Wire the NX-S11/12/21 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.
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-S11/12/21 as relay termi-
nals. Doing so might cause electric shock, fire or device failure.
Do not short-circuit the outputs. Doing so might cause
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) to prevent fire or
device failure.
