CHAPTER 5 SETTINGS AND PROCEDURE
BEFORE OPERATION
This chapter describes the procedure prior to the QD65PD2 operation, the name and setting of each part of the
QD65PD2, and the wiring method.
5.1 Handling Precautions
This section describes the precautions for handling the QD65PD2.
• Do not drop or apply strong shock to the module case or connectors.
• Do not remove the printed-circuit board of the module from its case.
Doing so may cause breakdowns.
• Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter can cause a
fire, failure, or malfunction.
• A protective film is attached to the top of the module to prevent foreign matter, such as wire chips, from
entering the module during wiring. Do not remove the film during wiring. Remove it for heat dissipation
before system operation.
• Tighten the screw within the specified torque range as follows. Undertightening can cause drop of the screw,
short circuit or malfunction. Overtightening can damage the screw and/or module, resulting in 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 screw if the module is subject to significant vibration.
• To mount the module, while pressing the module mounting lever located in the lower part of the module, fully
insert the module fixing projection(s) into the hole(s) in the base unit and press the module until it snaps into
place. Incorrect interconnection may cause malfunction, failure, or drop of the module.
When using the programmable controller in an environment of frequent vibrations, fix the module with a
screw.
