

Equipment must be correctly mounted so that the main terminal of the V9 series will not be touched
inadvertently. Otherwise, an accident or electric shock may occur.



Tighten the mounting screw on the fixtures of the V9 series to an equal torque of 0.6 N·m.
Excessive tightening may distort the panel surface. Loose mounting screws may cause the unit to fall down,
malfunction, or short-circuit.



Check periodically that terminal screws on the power supply terminal block and fixtures are firmly tightened.
Loosened screws or nuts may result in fire or malfunction.



Tighten the terminal screws on the power supply terminal block of the V9 series to an equal torque of 7.1 to
8.8 inch-lbf (0.8 to 1.0 N·m). Improper tightening of screws may result in fire, malfunction, or other serious
trouble.



The V9 series has a glass screen. Do not drop the unit or impart physical shocks to the unit. Otherwise, the
screen may be damaged.



Correctly connect cables to the terminals of the V9 series in accordance with the specified voltage and
wattage. Overvoltage, overwattage, or incorrect cable connection could cause fire, malfunction, or damage
to the unit.



Always ground the V9 series. The FG terminal must be used exclusively for the V9 series with the level of
grounding resistance less than 100



. Otherwise, electric shock or a fire may occur.



Prevent any conductive particles from entering the V9 series. Failure to do so may lead to fire, damage, or
malfunction.



After wiring is finished, remove the paper used as a dust cover before starting operation of the V9 series.
Operation with the dust cover attached may result in accidents, fire, malfunction, or other trouble.



Do not attempt to repair the V9 series yourself. Contact Hakko Electronics or the designated contractor for
repairs.



Do not repair, disassemble, or modify the V9 series. Hakko Electronics Co., Ltd. is not responsible for any
damages resulting from repair, disassembly, or modification of the unit that was performed by an
unauthorized person.



Do not use sharp-pointed tools to press touch switches. Doing so may damage the display unit.



Only experts are authorized to set up the unit, connect cables, and perform maintenance and inspection.



Lithium batteries contain combustible material such as lithium and organic solvents. Mishandling may cause
heat, explosion, or ignition resulting in fire or injury. Read the related manuals carefully and correctly handle
the lithium battery as instructed.



Do not press two or more positions on the screen at the same time. If two or more positions are pressed at
the same time, the switch located between the pressed positions may be activated.



Take safety precautions during operations such as changing settings when the unit is running, forced output,
and starting and stopping the unit. Any misoperations may cause unexpected machine movement, resulting
in machine accidents or damage.



In facilities where the failure of the V9 series could lead to accidents that threaten human life or other serious
damage, be sure that such facilities are equipped with adequate safeguards.



When disposing of the V9 series, it must be treated as industrial waste.



Before touching the V9 series, discharge static electricity from your body by touching grounded metal.
Excessive static electricity may cause malfunction or trouble.



Insert an SD card into the unit in the same orientation as pictured on the unit. Failure to do so may damage
the SD card or the slot on the unit.



The SD card access LED flashes red when the SD card is being accessed. Never remove the SD card or
turn off power to the unit while the LED is flashing. Doing so may destroy the data on the SD card. Check
that the LED has turned off before removing the SD card or turning off the power to the unit.
