GT10/GT30
Installation and Wiring

2.1 Installation
Power Supply Wiring
- For the power supply, use twisted wire (strand wire).
- There is sufficient noise resistance to offset power line noise, but we recommend
reducing noise by measures such as installing an insulated transformer.
- Separate wiring systems should be used for the power supply unit and the
operating unit.
Static Electricity/Noise
- Keep the GT10/GT30 main unit, PLC connecting cable, and other wiring as far
away as possible from machines which are likely to produce noise (welding
equipment, power lines, inverters, motors, etc.).
- For use in environments where the frequent occurrence of static electricity,
radiation, or induced noise can be expected, the use of shielded cable on all
wiring and grounding of shield (1-point ground) is recommended. When wiring
the equipment, shielded wires should be electrically insulated to signal lines and
signal grounds.
- If excessive static electricity is applied to the panel surface, the LCD display unit
may be damaged.
Battery Service Life
- The service life of the internal battery will be radically shortened if used
continually in ambient operating temperatures of more than 40
°
C/104
°
F
(50
°
C/122
°
F for the GT30) or when the operating voltage exceeds 25V DC. Use
caution when using the clock and device hold area functions.
Other Precautions
- Do not leave the GT10 connected to the TOOL port of the FP Programmer II.
- Always operate the touch panel with your fingers. Excessive load (about 98
N/cm
2
) or impact (operating with tools, etc.) will cause damage. Touch panel
operation must be within the standard operating power range. Uniform pressure
should be used to avoid abnormal wear of electrodes which may disable
operation. Operate the unit only by touch.
- Never dismantle, re-assemble, or alter the unit. Performance cannot be
warranted if this precaution is disregarded.
