[WIRING PRECAUTIONS]
Tighten the terminal screws of the GOT power supply section in the specified
torque range. Undertightening can cause a short circuit or malfunction.
Overtightening can cause a short circuit or malfunction due to the damage of
the screws or the GOT.
Exercise care to avoid foreign matter such as chips and wire offcuts entering
the GOT. Not doing so can cause a fire, failure or malfunction.
The module has an ingress prevention label on its top to prevent foreign
matter, such as wire offcuts, from entering the module during wiring.
Do not peel this label during wiring.
Before starting system operation, be sure to peel this label because of heat
dissipation.
Plug the communication cable into the connector of the connected unit and
tighten the mounting and terminal screws in the specified torque range.
Undertightening can cause a short circuit or malfunction.
Overtightening can cause a short circuit or malfunction due to the damage of
the screws or unit.
Plug the QnA/ACPU/Motion controller(A series) bus connection cable by
inserting it into the connector of the connected unit until it "clicks".
After plugging, check that it has been inserted snugly.
Not doing so can cause a malfunction due to a contact fault.
[TEST OPERATION PRECAUTIONS]
Before performing the test operations of the user creation monitor screen
(such as turning ON or OFF bit device, changing the word device current
value, changing the settings or current values of the timer or counter, and
changing the buffer memory current value), read through the manual carefully
and make yourself familiar with the operation method.
During test operation, never change the data of the devices which are used to
perform significant operation for the system.
False output or malfunction can cause an accident.
