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.
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-W, 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-W 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.)
Correctly wire the GOT power supply section after confirming the rated voltage and terminal
arrangement of the product.
Not doing so can cause a fire or failure.
Tighten the terminal screws of the GOT power supply section in the specified torque range.
Undertightening can cause a short circuit or malfunction.
Overtightening can cause a short circuit or malfunction due to the damage of the screws or the GOT.
Exercise care to avoid foreign matter such as chips and wire offcuts entering the GOT.
Not doing so can cause a fire, failure or malfunction.
Plug the communication cable into the connector to be connected, and tighten the mounting screws
and the terminal screws in the specified torque range.
Undertightening can cause a short circuit or malfunction.
Overtightening can cause a short circuit or malfunction due to the damage of the screws or unit.
