[WIRING PRECAUTIONS]
 Always ground the FG terminal of the Q62AD-DGH.
Not doing so can cause an electric shock or malfunction.
 When turning on the power and operating the module after wiring is completed, always attach
the terminal cover that comes with the product.
There is a risk of electric shock if the terminal cover is not attached.
 Use applicable solderless terminals and tighten them with the specified torque.If any solderless
spade terminal is used, it may be disconnected when the terminal screw comes loose, resulting
in failure.
 Tighten the terminal screws within the range of specified torque.
Undertightening can cause short circuit, fire, or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or
malfunction.
 Be careful not to let foreign matter such as sawdust or wire chips get inside the module.
They may cause fires, failure or malfunction.
 The top surface of the module is covered with protective film to prevent foreign objects such as
cable offcuts from entering the module when wiring.
Do not remove this film until the wiring is complete.
Before operating the system, be sure to remove the film to provide adequate ventilation.
[STARTING AND MAINTENANCE PRECAUTIONS]
 Do not touch the connector while the power is on.
Doing so may cause electric shock or malfunction.
 Be sure to switch off all phases of the externally supplied power used in the system before
cleaning the module or retightening the terminal screws, connector mounting screws, and
module fixing screws.
Not doing so may cause electric shock, or failure and malfunction of the module.
If the screws are loose, it may cause the module to fallout, short circuits, or malfunction.
If the screws are tightened too much, it may cause damages to the screws and/or the module,
resulting in the module falling out, short circuits or malfunction.
