[MOUNTING PRECAUTIONS]
For GT2512F-S, GT2510F-V, and GT2508F-V, attach an environmental protection sheet dedicated
to the open frame model (sold separately) to the display section.
Or, attach a user-prepared environmental protection sheet.
Not doing so may damage or soil the GOT or cause foreign matter to enter the GOT, resulting in a
failure or malfunction.
When installing the supplied fittings on GT2512F-S, GT2510F-V, or GT2508F-V, tighten screws in
the specified torque range (0.8 N•m to 1.0 N•m).
Meld studs on the control panel to fasten the fittings.
The studs must have strength adequate to withstand a tightening torque of 0.9 N•m or more.
Make sure that no foreign matter such as welding waste is at and around the bases of the studs.
Tighten nuts on the studs in the specified torque range (0.8 N•m to 0.9 N•m) with a wrench for M4
nuts.
Undertightening a screw or nut may cause the GOT to drop, short-circuit, or malfunction.
Overtightening a screw or nut may damage it or the GOT, causing the GOT to drop, short-circuit, or
malfunction.
Operate and store the GOT in environments without direct sunlight, high temperature, dust, humidity,
and vibrations.
When using the GOT in the environment of oil or chemicals, use the protective cover for oil.
Failure to do so may cause failure or malfunction due to the oil or chemical entering into the GOT.
[WIRING PRECAUTIONS]
Be sure to shut off all phases of the external power supply used by the system before wiring.
Failure to do so may result in an electric shock, product damage or malfunctions.
[WIRING PRECAUTIONS]
When grounding the FG terminal and LG terminal of the GOT power supply section, note the
following points.
Not doing so may cause an electric shock or malfunction.
• GT27, GT25, GT23, GT2107, GT2105-Q
Make sure to ground the FG terminal and LG terminal of the GOT power supply section solely for
the GOT (ground resistance: 100 Ω or less, ground cable diameter: 1.6 mm or more). (GT2705-V,
GT25-W, GT2107 and GT2105-Q do not have the LG terminal.)
• GT2104-R, GT2104-P, GT2103-P
Make sure to ground the FG terminal of the GOT power supply section with a ground resistance of
100 Ω or less. (For GT2104-PMBLS and GT2103-PMBLS, grounding is unnecessary.)
