3.1 Handling Precautions
This section describes the precautions on handling the module.
1) Do not drop or give a strong impact to the module case and/or connecter.
2) Do not remove the printed-circuit board of the module from the case.
Doing so may cause a failure.
3) Be careful to prevent foreign matters such as cutting chips or wire chips
from entering the module.
Failure to do so may cause a fire, failure or malfunction.
4) A protective film is attached to the module top to prevent foreign matter
such as wire chips from entering the module during wiring.
Do not remove the film during wiring.
Be sure to remove it for heat dissipation before system operation.
5) Tighten the module fixing screws within the following specified torque
range.
Insufficient tightening torque could result in a drop, short circuit or
malfunction.
Excessive tightening may damage the screw and/or the module, resulting
in a drop, short circuit or malfunction.

*1 The module can be easily fixed onto the base unit using the hook at the top
of the module.
However, it is recommended to secure the module with the module fixing
screws if the module is subject to significant vibration or shock.
6) When mounting the module to the base unit, insert the module fixing
projection into the fixing hole in the base unit, and mount the module using
the hole as a supporting point.
Incorrect module mounting may cause a malfunction, failure, or drop of the
module.
