Precautions (GT27, GT25, GT23, GT2107-W, GT2105)
■Treatment on power cables
For 100 V AC, 200 V AC, and 24 V DC cables, use thick wires as much as possible (Cable cross section: 0.75 mm
2
mm ), and make sure to twist them to the terminals.
To prevent a short circuit due to loose screws, use a solderless terminal with an insulation sleeve.
■Grounding
After connecting the LG terminal and the FG terminal, make sure to connect them to the ground.
Otherwise, the system is susceptible to noise.
The LG terminal has a potential equal to a half of the input voltage.
Therefore, touching the terminal may lead to an electric shock.
For GT2705-V, GT25-W, GT2107-W, and GT2105, ground only the FG terminal because the models do not have the LG
terminal.
Precautions (GT2104-R, GT2104-P, GT2103-P)
■Terminal processing of power cables
Connect a stranded wire or a solid wire directly, or use a rod terminal with an insulation sleeve.
Do not tighten the terminal screws in the specified torque range or more. Doing so can cause a failure or malfunction.
• When connecting a stranded wire or a solid wire directly
Twist the end of the stranded wire to prevent the elemental wires from protruding.
Do not apply solder plating on the wire terminal.

• When using a rod terminal with an insulation sleeve
A wire with a thick sheath cannot enter the insulation sleeve smoothly. Select a wire referring to the figure of external
dimensions below.

■Tool
Tighten the power supply terminal using a commercially-available small screwdriver. The tip of the screwdriver must be
straight and as wide as the shaft, as shown in the figure below.
