● Use the product within the environmental limits given in the catalog and manual. Use of the product inhigh-temperature or high-humidity environments, or in locations where it is exposed to condensation,
corrosive gas or large shock loads can create the risk of electrocution and fire.
● The HG2J-7U is designed for use in pollution degree 2. Use the HG2J-7U in environments of pollution
degree 2. (based on the IEC60664-1 rating)● Install the HG2J-7U according to the instructions in the User’s Manual. Improper installation will resultin falling, failure, electrical shock, fire hazard, or malfunction of the HG2J-7U.
● Prevent metal fragments or wire chips from dropping inside the HG2J-7U housing. Ingress of suchfragments and chips may cause fire hazard, damage, and malfunction.
● Use a power supply of the rated value. Using a wrong power supply may cause fire hazard.
● The HG2J-7U uses “ PS2 of EN61131 ” as DC power supply. (based on the IEC / EN61131 rating)● Use wire of a proper size to meet the voltage and current requirements.
● When exporting the HG2J-7U to Europe, use an EN60127 (IEC60127) approved fuse on the powerline outside the HG2J-7U.
● When exporting the HG2J-7U to Europe, use an EU-approved circuit protector.
● Make sure of safety before starting and stopping the HG2J-7U. Incorrect operation of the HG2J-7U
may cause mechanical damage or accidents.
● Use the HG2J-7U in a local area network if you download, upload or monitor the project data via the
Ethernet port.
● The touch panel of the HG2J-7U is made of glass, and will break if exposed to excessive shock.
Take due care when handling it.
● The protective film attached to the display of the programmable display is to protect the product fromscratches during transportation. Please remove the protective film before use. If the display is usedwith protective film, the film may become cloudy and stick to the display depending on the usage
environment and may become unremovable.
● Do not push hard or scratch the touch panel and protection sheet with a hard object such as a tool,
because they are damaged easily.
● For applications which require clock accuracy, adjust the clock periodically.
● Do not install the HG2J-7U in areas subjected to strong ultraviolet rays, since ultraviolet rays
may impair the quality of the LCD.
● Do not attempt to disassemble, repair or modify the HG2J-7U. This can create the risk of fire orelectrocution.
● When disposing of the HG2J-7U, do so as an industrial waste.
● Do not switch off the power or pull out the USB flash drive while it is being accessed, as this may
result in destruction of the stored data. If the data on the USB flash drive is corrupted, format the USB
flash drive.

Electrical Specifications● Make sure to turn off the power to the HG2J-7U before wiring each interface.

1such as applications for medical devices, nuclear power, railroads, aerospace, and automotive devices.
The HG2J-7U should not be used for such applications.
● Turn off the power to the HG2J-7U before installation, removal, wiring, maintenance, and inspectionof the HG2J-7U. Failure to turn power off may cause electrical shock or fire hazard.
● Special expertise is required to install, wire, configure, and operate the HG2J-7U. People without such
expertise must not use the HG2J-7U.
● The HG2J-7U uses an LCD (liquid crystal display) as a display device. The liquid inside the LCD is harmful
to the skin. If the LCD is broken and the liquid attaches to your skin or clothes, wash the liquid off
using soap, and consult a doctor immediately.
● Emergency and interlocking circuits must be configured outside of the HG2J-7U.
● Do not use touch switches for an emergency circuit or an interlocking circuit.
If the HG2J-7U fails, external equipment connected to the HG2J-7U will no longer be protected, andserious injury to operators and equipment damage may be caused.
● Stop using the HG2J-7U if it is accidentally dropped or exposed to significant shocks, check the
HG2J-7U for damage, and confirm that its various functions work safely and correctly.
● For the HG2J-7U connect the FG wire to grounding resistance of 100 Ω or less. Otherwise there is arisk of electric shock or mistaken operation.
● Although the screen will not be visible if the backlight of the HG2J-7U burns out, the touch panel willremain functional.
Incorrect touch panel operation will occur when operating the touch panel when the backlight appears
to be turned off but is actually burnt out. Because such erroneous operation could result in damage,the touch panel should not be used after the backlight has burned out.

8.4 Cautions for using the HG2J-7U connected to a personal computer
When connecting the HG2J-7U to a personal computer via the USB interfaces, the HG2J-7U or the
personal computer may break down depending on the conditions of the personal computer.
Make sure of the following cautions, in order to prevent an accident.
● If the personal computer has a 3-pin power plug or power plug with a ground lead type, make sure touse a plug socket including a ground input electrode or ground the earth lead, respectively.
● If the personal computer has a 2-pin power plug without ground lead, follow the procedure below
when connect the HG2J-7U to the personal computer.
(1) Pull out the power plug of the personal computer from the AC outlet.
(2) Connect the HG2J-7U to the personal computer.
(3) Insert the power plug of the personal computer into the AC outlet.

● Mount the HG2J-7U on a rigid panel.

About the printed contents of the main unit
“Mark A” indicates that you can refer to this instruction sheet by using the QR code.
For details, "8. Wiring" section.

● Do not tighten with excessive force, otherwise the HG2J-7U may warp on the display, or impair thewaterproof characteristics.

● If the mounting clips are tightened obliquely to the panel, the HG2J-7U may fall off the panel.
● When installing the HG2J-7U into a panel cut-out, make sure that the gasket is not twisted.

Especially when re-installing, take special care because any twists in the gasket will impair thewaterproof characteristics.

78Installation

7.1 Operating Environment
For designed performance and safety of the HG2J-7U, do not install the HG2J-7U in the following
environments:● Where dust, briny air, or iron particles exist.
● Where oil or chemical splashes for a long time.
● Where space is filled with oil mist.
● Where direct sunlight falls on the HG2J-7U.
● Where strong ultraviolet rays fall on the HG2J-7U.
● Where corrosive or combustible gasses exist.
● Where shocks or vibrations are transmitted.
● Where condensation occurs due to rapid temperature change.
● Where high-voltage or arc-generating equipment (electromagnetic contactors or circuit protectors)
exists in the vicinity.

Wiring● Turn off the power supply before wiring.

● Make the wiring as short as possible and run all wires as far away as possible from high-voltage andlarge-current cables. Follow all the procedures and precautions when wiring the HG2J-7U.
● Separate the HG2J-7U ower supply wiring from the power lines of I/O devices and motor equipment.
● Ground the functional earth terminal to make sure of correct operation.
● Use the SELV (Safety Extra-Low Voltage) circuit and LIM (Limited Energy) circuit for power supply.
● Use wire copper conductor only.
8.1 Power Supply Terminal● Pin assignment is shown in the following table.

7.2 Ambient Temperature● Allow sufficient space for ventilation, and install the equipment away from heat sources.
● Allow at least 100mm between the HG2J-7U and walls or other equipment.
● Do not install the HG2J-7U where the ambient temperature exceeds the rated operating ambient
temperature range. When mounting the HG2J-7U in such locations, provide a forced air-cooling fan
or air-conditioner to keep the ambient temperature within the rated temperature range.
7.3 HG2J-7U Orientation
The HG2J-7U is designed to install on a vertical landscape. The operating ambient temperature andthe output current of the USB interface (total of USB1 and USB2) are limited as shown in the tablebelow.

Check the terminals and connectors to make sure of no incomplete
insertion, or disconnected lines.
Make sure that all mounting clips and screws are tightened sufficiently.
If the mounting clips are loose, tighten the screw to the recommended
tightening torque.
The HG2J-7U’s backlight cannot be replaced by the customer.
