3. INSTALLATION
The following section explains the precautions when handling the
A1SJ71PB93D, from the time they are unpacked until they are installed.
For more details on the module installation, see the user's manual for
the PLC CPU used.
3.1 Handling Precautions
(1) Do not drop the module case or subject it to heavy impact since it is
made of resin.
(2) Do not remove the PCB of each module from its case. This may
cause a failure in the module.

module during wiring. In the event any foreign object enters,
remove it immediately.
(4) Tighten the module mounting screws and connector mounting
screws using torque within the following ranges.
