7.1 Power Supply Wiring
Connect the power supply to the power terminals on the back panel of the GOT.
Use a specified size power supply wire to prevent voltage drop, and tighten the terminal screws firmly to a
specified torque.
Do not exceed the number of wires that are allowed to be connected.
Secure the wires to prevent stress from being directly applied to the terminal block or wire connections.
In the case of GT1020-LBL, GOT power is supplied via the communication cable.
7.1.1 Cable types and wire end processing
Process the end of the electrical wire (solid or stranded), or attach a ferrules with plastic sleeve to the wire
end.
1 Electrical wire size
2 Wire end processing
(1) Connecting the wire directly
(a) Twist the end of the stranded wire. Make sure there are no wire whiskers.
(b) Do not solder the wire end.
(2) Using a ferrules with plastic sleeve to connect the wire
A wire with a too thick of a wire sheath may not fit the insulation sleeve.
Refer to the outline drawing for how to select the proper size wire.
7.1.2 Tools
Use a small driver with a straight, untapered blade as shown on the right to
tighten the power terminals.
