- Water leakage and dust a large amount of dust, powder and other conductive power, oil mist, salt, of
organic solvent exists.
- Mechanical vibrations of impacts are transmitted directly to the module body.
- Direct sunlight.
- Dew condensation due to sudden temperature change.
- High or low temperatures (outside the range of 0 to 55 °C)
2) Installing and Wiring.
- During wiring or other work do not allow any wire scraps to enter into it.
- Install it on locations that are convenient for operation.
- Make sure that it is not located near high voltage equipment located..
- Make sure that the distance from the walls of duct and external equipment be 50 mm or more.
- Be sure to be grounded to locations that have good ambient noise immunity.
3.1.2 Handling Precautions
▶ From unpacking to installing the thermocouple input module, be sure to check the following:
1) Do not drop it off, and make sure that strong impacts should not be applied.
2) Do not dismount printed circuit boards from the case. It can cause malfunctions.
