Mitsubishi Electric QD77MS User Manual page 9

When not using the module for a long time, disconnect the power line from the module or servo
amplifier.
Place the module and servo amplifier in static electricity preventing vinyl bags and store.
When storing for a long time, please contact with our sales representative.
Also, execute a trial operation.
Make sure that the connectors for the servo amplifier and peripheral devices have been securely
installed until a click is heard.
Not doing so could lead to a poor connection, resulting in erroneous input and output.
Use the programmable controller in an environment that meets the general specifications in the
user's manual for the CPU module used. Failure to do so may result in 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 programmable controller in an environment of frequent vibrations, fix the module
with a screw.
Tighten the screws 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.
Do not directly touch any conductive parts and electronic components of the module. Doing so
can cause malfunction or failure of the module.
When fumigants that contain halogen materials such as fluorine, chlorine, bromine, and iodine
are used for disinfecting and protecting wooden packaging from insects, they cause malfunction
when entering our products.
Please take necessary precautions to ensure that remaining materials from fumigant do not enter
our products, or treat packaging with methods other than fumigation (heat method). Additionally,
disinfect and protect wood from insects before packing products.
The module and the servo amplifier must not be used with parts which contain halogen-series
flame retardant materials (such as bromine) under coexisting conditions.
(4) Wiring
Shut off the external power supply (all phases) used in the system before wiring.
Failure to do so may result in electric shock or cause the module to fail or malfunction.
