2.1 Installation
2.1.1 Installation Environment
When installing and using the GT series, always make sure the following conditions are
observed.
Usage Conditions
When installing the product, make sure it is used within the range of the general
specifications. Do not use in the following environments:
– Areas where the unit may come in contact with water (the unit is warranted by
IP65 for the installed panel, but this applies to initial values and operation cannot
be guaranteed in areas where the unit is constantly subjected to water or to
extreme temperatures or humidity).
– Areas where the ambient temperature exceeds the range 0
°
C to 40
°
C/32
°
F to
104
°
F (0
°
C to 50
°
C/32
°
F to 122
°
F for the GT30).
– Areas where the ambient humidity exceeds 20% RH to 85% RH.
– If the control panel and other parts are installed in an environment where the air
tends to be poorly ventilated, forced cooling should be used to keep the ambient
temperature of the from going over 40
°
C/104
°
F (50
°
C/122
°
F for the GT30). This
prevents the temperature of the GT display unit from rising.
– Locations where condensation may form because of sudden fluctuations in
temperature.
– Locations where flammable or corrosive gases are present.
– Locations where there are high concentrations of dust or iron filings.
– Locations where substances such as organic solvents (thinner, benzene, etc.) or
strong alkali substances (ammonia, caustic soda, etc.) might adhere to the
product.
– Locations where the product is subject to extreme vibration and/or impact.
– Avoid installing the product near high–voltage lines, high–voltage devices, power
lines, power devices, amateur radio sets and other transmitters, and devices that
generate strong current surges.
– Avoid locations where the display unit is subject to direct sunlight.
Safety Precautions
– The switch functions of the programmable display unit should not be used to
design systems which may pose a threat to human life or which may cause
severe injury or damage. Designs should include safety mechanisms for use in
the event that switch functions do not function correctly.
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.
