[WIRING PRECAUTIONS]
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. (GT27, GT25 Only)
[TEST OPERATION PRECAUTIONS]
Before testing the operation of a user-created monitor screen (such as turning on or off a bit device,
changing the current value of a word device, changing the set value or current value of a timer or
counter, and changing the current value of a buffer memory), thoroughly read the manual to fully
understand the operating procedures.
During the 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.
[STARTUP/MAINTENANCE PRECAUTIONS]
When power is on, do not touch the terminals.
Doing so can cause an electric shock or malfunction.
Correctly connect the battery connector.
Do not charge, disassemble, heat, short-circuit, solder, or throw the battery into the fire.
Doing so will cause the battery to produce heat, explode, or ignite, resulting in injury and fire.
Before starting cleaning or terminal screw retightening, always switch off the power externally in all
phases.
Not switching the power off in all phases can cause a unit failure or malfunction.
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.
