WARNING
Power supply
To prevent a fire hazard, ensure that the power supply voltage specified for the product matches the local line voltage before
connecting the system to the DC power. When using the optional AC adapter, check the voltage range of the AC power
outlet before connecting.
AC adapter
To prevent an electric shock or fire hazard, use an optional accessory AC adapter (SA-10A-EDS).
Avoid using in environment with inflammable gas, etc.
To prevent the risk of fire hazard or explosion, do not use the product in an environment with inflammable gas, vapor, or
dust.
If any trouble occurs
To prevent a fire hazard, if smoke is emerging from the product, immediately turn OFF the power switch and disconnect the
DC power cable or AC adapter to terminate the system operation.
In case if any foreign matters or water are entered or the product is dropped, immediately turn OFF the power.
When it started thundering, do not touch the product or cables. Otherwise, it may cause electric shock.
Protective ground
Be sure to connect the GND terminal to the ground. Otherwise, it may cause an electric shock hazard, lower the
performance, and cause trouble.

To prevent troubles and accidents caused by erroneous handling and installation, fully understand the operating instructions and
operating environment and properly use the product with special care to have the product safely fulfill its performance.
CAUTION

Do not use the product outdoors.
Otherwise, it may cause an electric shock, fire hazard, lower the performance and cause trouble.
Before touching terminals of the product, be sure to discharge static electricity from your body.
Otherwise, it may lower the performance and other issues may occur.
When using the NTB-51A, the following points should be remembered.
Do not use the product in an environment where the wind blows directly to terminals. Otherwise, it may lower the
performance and interrupt the measurements. If use under direct wind is inevitable, prepare a windshield or take proper
measures.
When soldering lead wires, do not heat the lugs of the soldering, screw-fixed terminal block for a long time by using a
soldering iron. Otherwise, it may damage the terminal block plastic and internal PCB.
Wire the product properly based on the terminal array.
To prevent short-circuit trouble, fasten screws on a terminal block.
Use the product with the temperature ranging from -10 to 50℃.
Otherwise, it may lower the performance and other issues may occur.
If use under direct sunlight or in a cold place is inevitable, prepare a sunscreen or take proper measures to keep it warm.
Use the product in the specified operating humidity range 20 to 85%.
Use in a humid place exceeding the specified range or where it is exposed to splashing water may lower the performance
and cause trouble.
Do not use the product immediately after the change in the environment.
Allow the product adequate time to adjust to the ambient environment prior to use.
In addition, abrupt changes in ambient temperature during transportation, etc. may cause condensation, which may result in
lower performance and or damage the system.
