[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). (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.)
When tightening the terminal screws, use the following screwdrivers.
• GT27, GT25, GT23, GT2107, GT2105-Q
Use a Phillips-head screwdriver No. 2.
• GT2104-R, GT2104-P, GT2103-P
For the usable screwdrivers, refer to the following.
➠ GOT2000 Series User's Manual (Hardware)
Tighten the terminal screws of the GOT power supply section in the following specified torque range.
• GT27, GT25, GT23
Specified torque range (0.5 N•m to 0.8 N•m)
For a terminal processing of a wire to the GOT power supply section, use the following terminal.
• GT27, GT25, GT23, GT2107, GT2105-Q
Use applicable solderless terminals for terminal processing of a wire and tighten them with the
specified torque.
Not doing so can cause a fire, failure or malfunction.
• GT2104-R, GT2104-P, GT2103-P
Connect a stranded wire or a solid wire directly, or use a rod terminal with an insulation sleeve.
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 following specified torque range.
• GT27, GT25, GT23, GT2107, GT2105-Q
Specified torque range (0.5 N•m to 0.8 N•m)
• GT2104-R, GT2104-P, GT2103-P
Specified torque range (0.22 N•m to 0.25 N•m)
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.
The module has an ingress prevention label on its top to prevent foreign matter, such as wire offcuts,
from entering the module during wiring.
Do not peel this label during wiring.Before starting system operation, be sure to peel this label
because of heat dissipation. (GT27, GT25 Only)
Plug the communication cable into the GOT interface or the connector of the connected unit, 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.
