• Disconnecting the cable between a support tool and the NA Unit.
• Do not connect an AC power supply to the DC power terminals.
• Do not perform a dielectric strength test.
• Use a DC power with a slight voltage fluctuation and that will provide a stable output even if the input
is momentarily interrupted for 10 ms. Also use the one with reinforced insulation or double insulation.
Rated Power Supply Voltage: 24 VDC (Allowable range 19.2 to 28.8 VDC)
• Use a power cable with AWG#12 to #22 thick (0.35 mm
and tighten the terminal screw with the torque in the range of 0.5 to 0.6 N·m. Also confirm if the termi-
nal screw is tighten appropriately.
• Ground the NA Unit correctly.
• When using the NA5-W-V1, to help prevent electrical shock, ground to 100 Ω or less by
using dedicated ground wires (with cross-section area of 2 mm
screw on the protective ground terminal to a torque of 1.0 to 1.2 N·m.
• Do not use any battery if strong impact is applied to it (e.g. by dropping on the floor) because such a
battery may cause a leakage.
• Confirm the type of the battery to install the battery properly.
• Apply power for at least five minutes before changing the battery. Mount a new battery within five
minutes after turning OFF the power supply. If power is not supplied for at least five minutes, the
clock data may be lost. Check the clock data after changing the battery.
• Do not dismantle a battery nor let it short-circuit.
• Do not apply an impact with the lithium battery, charge it, dispose it into a fire, or heat it. Doing either
of them may cause an ignition or a bursting.
• Dispose of the NA Units and batteries according to local ordinances as they apply.
• The following precaution must be displayed on all products containing lithium primary batteries with a
perchlorate content of 6 ppb or higher when exporting them to or shipping them through California,
USA.
Perchlorate Material - special handling may apply.
See www.dtsc.ca.gov/hazardouswaste/perchlorate
The NA-Series contains a lithium primary battery with a perchlorate content of 6 ppb or higher. When
exporting a product containing the NA-Series to or shipping such a product through California, USA,
label all packing and shipping containers appropriately.
• Do not connect the USB devices in the environment subject to the strong vibration.
• Use a USB memory device for temporary purposes such as data transfer.
• Do not connect USB devices which are not allowed to connect to NA Unit.
• Start actual system application only after checking normal operation of the system including storage
devices such as USB memory and SD card.
• When connecting peripheral devices which do not meet the performance level of the NA Unit for
noise and static electricity, ensure sufficient countermeasures against noise and static electricity dur-
ing installation of the peripheral devices to the NA Unit.
• Do not carry out the following operations when accessing USB devices or SD card:
• Turning OFF the power supply of the NA Unit
• Press the Reset switch of the NA Unit
• Pull out the USB devices or SD card
• When using the No. 6 pin of the serial port connector for a voltage of DC+5 V, make sure the supply
equipment's current capacity is below 250 mA before using it. The DC+5 V voltage output of the NA
Unit is +5 V±5%, and the maximum current is 250 mA.
