4. Mounting and Installation
This section describes the handling precautions for procedures from
unpacking to installation of the A1SJ71AP21/AR21 and its installation
environment.
For details, refer to the user's manual for your PLC CPU.
4.1 Handling Precautions
In this section, handling precautions for the module are described.
(1) The module case is made of resin, so do not drop it or apply strong
impacts on it.
(2) Do not remove the PC board from the module case. This may cause a
fault.
(3) Be careful to prevent foreign matter from entering from the module top
during wiring.
(4) Tighten the module fixing screws within the following ranges.

4.2 Installation Environment
Do not install PLCs in the following environments:
(1) Locations where the ambient temperature is outside the range 0
55 .
(2) Locations where the ambient humidity is outside the range 10% RH to
90%RH.
(3) Locations where dewing occurs due to sudden temperature changes.
(4) Locations exposed to corrosive or combustible gases.
(5) Locations exposed to large amounts of highly conductive dust, iron
powder, oil mist, salt or organic solvents.
(6) Locations where the module is exposed to direct sunlight.
(7) Locations where a strong electric or magnetic field is generated.
(8) Locations where the module will be subject to direct vibration or
impact.

5.3 Securing space for the cables
The radius of the fiber-optic cables or coaxial cables must not be smaller
than the allowable bend radius.
When connecting a fiber-optic cable or coaxial cable to a link module, make
sure that there is enough space for the cable to be bent to a larger radius
than the allowable bend radius.
For connector A and bend radius r of the fiber-optic cable, contact Mitsubishi
Electric System & Service Corporation.
