Power Supply Cautions
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.

Grounding Cautions
• 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.

Input/Output Signal Line Cautions
• 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.

Maintenance and Periodic Inspection
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.

Backlight
• The ST unit's backlights cannot be replaced by the customer. When the back-
lights need to be replaced, please contST403-AG41-24Vact your local ST dis-
tributor.
