OPERATION
This chapter describes the operating procedures before operation, part names, settings,
and wiring of the QD63P6.
4.1
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 fixing screws within the following torque 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.
* 1 The module can be easily mounted to a base unit, using the hook on the upper part of the module.
However, it is recommended to secure it with the module fixing screws when used in an
environment where constant vibrations may occur.
(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.
