P
DANGER

● Switch OFF the power supply of the operator terminal before starting
the installation work or wiring and before mounting or removing the
option function board.
● When the communication between the operation terminal and the
PLC fails it is impossible to operate keys or devices via the operation
terminal. Therefore emergency stops and other safety functions must
not be controlled via the PLC.
E
CAUTION
● Do not disassemble or modify the unit. Doing so can cause a failure,
malfunction, injury or fire.
● Use the GOT in the environment that satisfies the general specifica-
tions described in this manual. Don't mount the operation terminal in
an enviroment that contains high explosive risks, strong magnetic
fields, direct sunlight or large, sudden temperature changes.
B
● Never allow fluids, metal filings or wiring debris to enter any openings

Mounting
A GOT is designed to be installed into the door of a control cabinet or into
a control panel.
When the temperature inside the control cabinet or
control panel is 40 to 55 °C the mounting angle
105°
should be in the range 60° to 105° degrees.
GOT
60°
Prepare a hole in the panel with the dimensions shown on the left.
Insert the GOT from the front of the
panel or the control cabinet into
the cut out.
E
GOT
Place the mounting fittings (sup-
plied) into the provided openings
of the GOT and tighten the screws
until the GOT is fixed. Please use all
four supplied mounting fittings
and tighten the mounting screws
with a torque of 0.36 to 0.48 Nm.
After mounting, remove the protection film from the operator terminal
display.
Power Supply Wiring
E
CAUTION
● Do not lay signal cables close to the main circuit, high-voltage power
lines, or load lines. Otherwise effects of noise or surge induction are
likely to take place. Keep a safe distance of more than 100 mm from
the above when wiring.
● When connecting the power supply please confirm the rated voltage
and the polarity. Not doing so can cause a fire or failure.
Connect the power supply to the power terminals on the back panel of the GOT.

Grounding
Ground the GOT using the ground terminal at the lower left corner of the oper-
ator terminal (Refer to the figure at the top of this column).
● The grounding resistance should be 100
● The grounding point should be close to the GOT. Keep the grounding wires
as short as possible.
Cut out
● The ground wire size should be at least 2 mm
● Independent grounding should be performed for best results. When inde-
pendent grounding is not performed, perform "shared grounding" of the

Connection to the control system
An operator panel of the GOT2000 series can be connected not only to PLCs
from Mitsubishi Electric but also to inverters, servo amplifiers, CNC as well and
to PLCs from third party manufacturers and many other devices. For further
