The peripheral units, such as the control unit and CRT/MDI, have been
designed on the assumption that they are housed in closed cabinets. In
this manual “cabinet” refers to the following:
D Cabinet manufactured by the machine tool builder for housing
the control unit or peripheral units;
D Operation pendant for housing the CRT/MDI or operator’s
panel.
D Equivalent to the above.
The environmental conditions of internal unit when installing these
cabinets shall conform to the following table.
Ambient
In operation 0_Cto 55_C
temperature
In store or transportation –20_C to +60_C
Relative humidity
30% to 95%
(no condensation)
Vibration
In operation: 0.5G or less
In store or transportation: 1.0G or less
Pollutant
Special care should be taken.
Each unit should be placed in a cabinet to keep it from
pollutants (such as dust, coolant, organic solvents,
acid, corrosive gas, and salt).
Heat sink of outer of cabinet: The heat sinks should
be protected from direct exposure to coolant, lubri-
cant, and metal chips.
Radiation
(ionizing or nonion-
izing)
If a unit is to be used in an environment where it is
likely to be exposed to radiations (such as microwave,
ultraviolet rays, laser beams, and X–rays), a shielding
provision should be available for it.
Height above sea
level
In operation: Up to 1,000 m
In store or transportation: Up to 12,000 m
NOTE
Relative humidity of DPL/MDI is below :
In operation : 20 to 85% (no condensation)
In store or transportation : 20 to 90% (no condensation)
Section 3.3 describes the installation and design conditions of a cabinet
satisfying these conditions.
