USING THE ROBOT SAFEL
Y
Storage humidity
Storage humidity Below 95% RH (no condensation)
The controller should be stored in a location at an ambient humidity below 95% RH
(no condensation) when not being used. If the robot controller is stored in a location
at high humidity for an extended period of time, rust may form on the electronic
components in the robot controller.
Vibration and shock
Do not apply strong shocks to the controller. Do not install the controller in locations
subject to large vibrations or shocks. The controller may malfunction or break down
if subjected to large vibrations or shocks.
Environments
The controller is not designed to meet explosion-proof, dust-proof, and drip-proof
specifications, and so do not use it in the following locations. If used in these
locations, component corrosion, improper installation, or fire may result.
1) Environments containing combustible gases or dust particles, or flammable liquids,
etc.
2) Environments where conductive substances such as metal cutting chips are
present.
3) Environments where water, cutting water, oils, dust, metal particles, or organic
solvents are present.
4) Environments containing corrosive gases or substances such as acid or alkali.
5) Environments containing mist such as cutting fluids or grinding fluids.
If using the controller in locations where dust particles of gases may generate, it is
recommended to install the controller in a box with a cooling unit.
Installation location
Always install the robot controller indoors, at a height of less than 1000 meters above
sea level.
Install the controller in a control panel with a structure that does not allow water, oil,
carbon or dust particles to penetrate it.
Do not install the controller in the following locations:
1) Near devices which may be a source of electrical noise, such as large inverters,
high-output high-frequency generators, large contactors, and welding machines.
2) Locations where electrostatic noise is generated.
3) Locations subject to radio frequency interference.
4) Locations where there is a possibility of exposure to radioactivity.
5) Locations where dangerous items such as ignitable, flammable or explosive
materials are present.
6) Near combustible materials.
7) Environments exposed to direct sunlight.
8) Narrow space where tasks (teaching, inspections, etc.) cannot be performed
safely.
