Installation Precautions - Mitsubishi Electric Q12DCCPU-V User Manual

[Design Precautions]
Do not install the control lines or communication cables together with the main circuit lines or power
cables.
Keep a distance of 100mm (3.94 inches) or more between them.
Failure to do so may result in malfunction due to noise.
When a device such as a lamp, heater, or solenoid valve is controlled through an output module, a
large current (approximately ten times greater than normal) may flow when the output is turned from
off to on. Take measures such as replacing the module with one having a sufficient current rating.
After the C Controller module is powered on or is reset, the time taken to enter the RUN status varies
depending on the system configuration, parameter setting, and/or program size.
Design circuits so that the entire system will always operate safely, regardless of the time.

[Installation Precautions]

Use the C Controller module in an environment that meets the general specifications in this manual.
Failure to do so may result in an electric shock, fire, malfunction, or damage to or deterioration of the
product.
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 mounting may cause malfunction, failure or drop of the module.
When using the module in an environment of frequent vibrations, fix the module with a screw.
Tighten the screw within the specified torque range.
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.
