CAUTION
•
Exercise care to avoid foreign matter such as chips and wire offcuts entering the
module.
Not doing so can cause a fire, failure or malfunction.
•
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 module.
•
Plug the bus connection cable by inserting it into the connector of the connected
module until it "clicks".
After plugging, check that it has been inserted snugly.
Not doing so can cause a malfunction due to a contact fault.
•
Plug the communication cable into the connector of the connected module 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 module.
•
Do not touch the conductive and electronic parts of the module directly.
Doing so can cause a module malfunction or failure.
(1) Do not drop the module or give it strong impact.
Doing so can cause a failure because the display device is made of glass.
(2) Do not remove the printed circuit board of the module from the case.
Doing so can cause a failure.
(3) When mounting the main unit to a control box or the like, set the display section as
shown below.
• When the temperature inside the enclosure is 40 to 55°C or less, the mounting
angle should be in the range 60 to 105 degrees.

• The GOT will be deteriorated earlier if it is used at the mounting angle other than
the above. Therefore, the temperature inside the enclosure should be within 40°C.
(4) Tighten the screws in the following specified range.
