[WIRING PRECAUTIONS]
CAUTION
● Tighten the terminal screws of the GOT power supply section in the following specified torque range.
[GT27, GT25, GT23, GT2107-W, GT2105-Q]
Specified torque range (0.5 N•m to 0.8 N•m)
[GT2104-R, GT2104-P, GT2103-P]
Specified torque range (0.22 N•m to 0.25 N•m)
● 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 labelbecause
of heat dissipation. (GT27, GT25 Only)
● Plug the communication cable into the GOT interface or the connector of the connected unit,
andtighten the mounting screws and the 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 theconnector
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)
● When you use the Handy GOT, run the connected cable in ducts or clamp the cable.
Not doing so can cause the unit or cable to be damaged due to the dangling, motion or
accidentalpulling of the cables or can cause a malfunction due to a cable connection fault.
● When you remove a cable from the Handy GOT, do not pull the cable portion.
Doing so can cause the unit or cable to be damaged or can cause a malfunction due to a
cableconnection fault.
[TEST OPERATION PRECAUTIONS]
WARNING
● 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.
