Power Supply Wiring to the GOT
The following shows the examples of wiring the power cable, ground cable and other cables to the GOT power supply
terminal.
Ground cable
■1. Precautions (GT27, GT25, GT2107, GT2105)
(1) 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
to 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.
(2) 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, GT2105 connect only the FG terminal because the model does not have the LG terminal.
