• When attaching a wire to the ST's rear face FG terminal, (on the Power Input
Terminal Block), be sure to create an exclusive ground.

• The FG terminal and the ST's internal 0V power are connected. Be sure to con-
firm that this type of connection is allowed in your current system.
Please pay special attention to the following instructions when connecting the power
cord. Use the power plug and connects to the ST power connector.
• Between the line and the ground, be sure to use a low-noise power supply.
• Input and Output signal lines must be separated from all power control cables
used for operational circuits.
• To increase noise resistance, be sure to twist the ends of the power cord wires
before connecting them to the ST power connector.
• The ST's power supply cord should not be bundled with or kept close to main
circuit lines (high voltage, high current), or input/output signal lines.
• Connect a surge absorber to handle power surges.
• To reduce noise, make the power cord as short as possible.
• All ST Input and Output signal lines must be separated from all operating circuit
(power) cords.
• If this is not possible, use a shielded cord and ground the shield.

Power Supply Cautions
When dirt collects on the surface or the frame of the display, soak a soft cloth in
water with a neutral detergent, wiring the cloth tightly, and wipe the display.
• Do not use paint thinner, organic solvents, or strong acid com-
pounds to clean the unit.
• Do not use hard or pointed objects to operate the touch-screen
panel, since it can damage the panel surface.
