• Be certain to read this manual carefully before performing installation, wiring, or maintenance work, or operating
the HG5G/4G/3G/2G-V, HG4G/3G, HG2G-5F/-5T, HG1G/1P.
• The HG5G/4G/3G/2G-V, HG4G/3G, HG2G-5F/-5T, HG1G/1P has been manufactured with careful regard to quality.
However, if you intend to use this product in applications where failure of this equipment may result in damage to
property or injury, ensure that it used in conjunction with appropriate fail-safe backup equipment.
• In this manual, safety precautions are categorized in order of importance to Warning and Caution:
• When using the HG5G/4G/3G/2G-V, HG4G/3G, HG2G-5F/-5T, HG1G/1P in applications which require high level of
safety, add a failsafe or backup functionality, and verify an adequate level of safety using the product specifications.
• Turn off the power to the HG5G/4G/3G/2G-V, HG4G/3G, HG2G-5F/-5T, HG1G/1P before installation, removal,
wiring, maintenance, and inspection of the HG5G/4G/3G/2G-V, HG4G/3G, HG2G-5F/-5T, HG1G/1P. Failure to
turn power off may cause electrical shock or fire hazard.
• Special expertise is required to install, wire, configure, and operate the HG5G/4G/3G/2G-V, HG4G/3G, HG2G-5F/-5T,
HG1G/1P. People without such expertise must not use the HG5G/4G/3G/2G-V, HG4G/3G, HG2G-5F/-5T, HG1G/1P.
• The HG5G/4G/3G/2G-V, HG4G/3G, HG2G-5F/-5T, HG1G/1P 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 HG5G/4G/3G/2G-V, HG4G/3G, HG2G-5F/-5T,
HG1G/1P.
• Do not use touch switches and the function keys for an emergency circuit or an interlocking circuit. If the HG5G/
4G/3G/2G-V, HG4G/3G, HG2G-5F/-5T, HG1G/1P fails, equipment connected to the HG5G/4G/3G/2G-V, HG4G/3G,
HG2G-5F/-5T, HG1G/1P will no longer be protected, and serious injury to operators and equipment damage may
be caused.
• For the emergency stop switch and the enabling switch on the HG1P, note the following points:
- Connect the emergency stop switch to function as either a category 0 or category 1 stop in accordance with
IEC/EN60204-1.
- Perform regular checks to confirm that the emergency stop switch and enabling switch work properly. It is
extremely dangerous if the enabling switch no longer returns to position 1 due to a foreign object becoming
lodged in the switch.
- Do not, under any circumstances, hold the enabling switch in position 2 with tape, string, or deform the
rubber cover. The function of the enabling switch will be lost, and the enabling switch may not work in an
emergency.
- Place your finger firmly on the enabling switch.
• Stop using the HG5G/4G/3G/2G-V, HG4G/3G, HG2G-5F/-5T, HG1G/1P if it is accidentally dropped or exposed to
significant shock, check the HG5G/4G/3G/2G-V, HG4G/3G, HG2G-5F/-5T, HG1G/1P for damage, and confirm that
its various functions work safely and correctly.
• For the HG5G/4G/3G/2G-V, HG4G/3G, HG2G-5F/-5T, HG1G/1P, connect the FG wire to grounding resistance of
100 Ω or less. Otherwise there is a risk of electric shock or mistaken operation.
• The screen will not be visible if the backlight of the HG5G/4G/3G/2G-V, HG4G/3G, HG2G-5F/-5T, HG1G/1P burns
out, the touch panel and the function keys will remain functional. Incorrect touch panel operation or incorrect
function key operation will occur when operating the touch panel when the backlight appears to be off but is
actually burnt out. Because such erroneous operations could result in damage, the touch panel and the function
key should not be used after the backlight has burned out.
• When more than one button is pressed at the same time, due to the detection characteristics of an analog type
touch panel, only the center of the pressed area is sensed and the unit assumes that only one button is pressed.
Therefore, do not operate the HG5G/4G/3G/2G-V, HG4G/3G, HG2G-5F/-5T, HG1G/1P by pressing more than one
button simultaneously.
