Mitsubishi Electric GOT 1000 Connection Manual page 4

[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 POWER LED flickers (green/orange) and the display section
turns black and causes the monitor screen to appear blank, while the input of the touch switch(s)
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 POWER LED flickers (green/orange) and the monitor screen appears blank.
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]
Be sure to shut off all phases of the external power supply used by the system before mounting or
removing the GOT to/from the panel.
Not doing so can cause the GOT to fail or malfunction.
Be sure to shut off all phases of the external power supply used by the system before mounting or
removing the communication unit, option function board or multi-color display board onto/from the GOT.
Not doing so can cause the unit to fail or malfunction.
Before mounting an optional function board or Multi-color display board, wear a static discharge wrist
strap to prevent the board from being damaged by static electricity.
Use the GOT in the environment that satisfies the general specifications described in this manual.
Not doing so can cause an electric shock, fire, malfunction or product damage or deterioration.
When mounting the GOT to the control panel, tighten the mounting screws in the specified torque
range.
Undertightening can cause the GOT to drop, short circuit or malfunction.
Overtightening can cause a drop, short circuit or malfunction due to the damage of the screws or the
GOT.
