The following is explanations of the handling precautions and
installation environment which is common to modules when handling
D75P2 from unpacking to installation.
For the details of loading and installation of the module, refer to User's
Manual of programmable controller CPU module to be used.
4.1 Handling precautions
1) The module case is made of plastic. Be sure not to drop it
or subject it to strong vibration.
2) Do not remove the printed circuit board of the module from
the case. This may cause malfunctions.
3) Be careful not to let foreign matters such as filings or wire
chips get inside the module during wiring. When such
matters do enter, be sure to remove them.
4) Tighten the module installation screws and terminal screws
within the following tightening torque range.
4.2 Installation environment
Do not install the A series programmable controller in the following
environments.
1) Where the ambient temperature exceeds the 0 to 55°C
range.
2) Where the ambient humidity exceeds the 10 to 90 % RH
range.
3) Where condensation is produced by sudden temperature
changes.
4) Where corrosive or combustible gas is present.
5) Where dust, iron powder and other conductive powder, oil
mist, salt, or organic solvents are prevalent.
6) In direct sunlight.
7) Where a strong electric or magnetic field is generated.
8) Where vibration and shock may be transmitted directly to
the module.
