Mitsubishi Electric A960GOT User Manual page 3

[Design Precautions]
• Incorrect operation of the touch switch(s) may lead to a serious accident if the GOT backlight is
gone out.
When the GOT backlight goes out, the display section turns black and causes the monitor
screen to appear blank, while the input of the touch switch(s) still remains active.
This may confuse an operator in thinking that the GOT is in "screensaver" mode, who then tries
to release the GOT from this mode by touching the display section, which may cause a touch
switch to operate.
Note that the following occurs on the GOT when the backlight goes out.
• The monitor screen disappears even when the screensaver is not set.
• The monitor screen will not come back on by touching the display section, even if the
screensaver is set.
• Do not bundle the control and communication cables with main-circuit, power or other wiring.
Run the above cables separately from such wiring and keep them a minimum of 100mm apart.
Not doing so noise can cause a malfunction.
[Mounting Precautions]
• Before installing or removing the GOT main unit to or from an enclosure, always switch off the
GOT power externally in all phases.
Not doing so can cause a module failure or malfunction.
• Before loading or unloading the communication board, communication module or memory board
to or from the GOT, always switch off the GOT power externally in all phases.
Not doing so can cause a module failure or malfunction.
• The GOT should be used in the environment given in the general specifications of the GOT
user's manual.
Not doing so can cause an electric shock, fire, malfunction or product damage or deterioration.
• When mounting the GOT main unit to an enclosure, tighten the mounting screws in the specified
torque range.
Undertightening can cause a drop, short circuit or malfunction.
Overtightening can cause a drop, short circuit or malfunction due to the damage of the screws
or module.
