9. Do not use in an area where dust, powder dust, water or oil is in the air.
It will cause failure or malfunction.
10. Do not use in an area where a magnetic field is generated.
It will cause failure or malfunction.
11. Do not
install in the environment of flammable gas, corrosive gas and explosive gas.
It could lead to fire, explosion and corrosion.
12. Radiant heat from strong heat supplys such as a furnace, direct sunlight, etc. should not be
applied to the product.
It will cause failure of the gateway unit or its peripheral devices.
13. Do not use the product in an environment subject to a temperature cycle.
It will cause failure of the gateway unit or its peripheral devices.
14. Do not use in a place where surges are generated.
When there are units that generate a large amount of surge around the product (e.g., solenoid type
lifters, high frequency induction furnaces, motors, etc.), this may cause deterioration or damage to
the product’s' internal circuit. Avoid supplys of surge generation and crossed lines.
15. The product is not immune to lightening strikes. Take measures against lightening strikes in
the system.
16. Do not install this product in an environment under the effect of vibrations and impacts.
It will cause failure or malfunction.
17. If this product is used with a relay or solenoid valve, they should be the surge absorbing
element built-in type.
16.3 Mounting
1. The
gateway unit
and its peripheral devices should be installed on a fire-proof material.
A direct installation on or near a flammable material may cause fire.
2. Do not install this product in a place subject to vibrations and impacts.
It may cause an electric shock, fire, or injury.
3. Take measure so that the operating temperature of this
gateway unit
and its peripheral
devices are within the range of the specifications. Also, this controller should be installed
with 50mm or larger spaces between each side of it and the other structures or components.
It may cause a malfunction of the controller and its peripheral devices and a fire.
4. Do not mount this
gateway unit
and its peripheral devices together with a large-sized
electromagnetic contactor or no-fuse breaker, which generates vibration, on the same panel.
Mount them on different panels, or keep the controller and its peripheral devices away from
such a vibration supply.
5. This
gateway unit
and its peripheral devices should be installed on a flat surface.
If the mounting surface is distorted or not flat, an unacceptable force may be added to the housing,
etc. to cause troubles.
