Handling Precautions

This section describes precautions on handling the QD63P6.
(1) Do not drop the module case and/or connector or apply a strong impact
to it.
(2) Do not remove the printed-circuit board of the module from the case.
Doing so will cause failure.
(3) Be careful to prevent foreign matter such as wire chips from entering the
module.
Failure to do 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 screws such as module fixing screws within the following
ranges.
If the screw is too loose, it may cause a drop, short circuit, or
malfunction.
Excessive tightening may damage the screw and/or the module,
resulting in a drop, short circuit or malfunction.

However, it is recommended to secure the module with the module fixing screw if the module is
subject to significant vibration.
(6) To mount the module on the base unit, fully insert the module fixing
projection into the fixing hole in the base unit and press the module
using the hole as a fulcrum.
Incorrect module mounting may cause a malfunction, failure, or drop of
the module.
