ESD Precautions
Integrated circuits on computer boards are sensitive to static electricity. To
avoid damaging chips from electrostatic discharge, observe the following
precautions:
 Do not remove boards or integrated circuits from their anti-static
packaging until you are ready to install them.
 Before handling a board or integrated circuit, touch an unpainted
portion of the system unit chassis for a few seconds. This helps to
discharge any static electricity on your body.
 Wear a wrist-grounding strap, available from most electronic
component stores, when handling boards and components.

Installation Instructions
2.1 Mounting Instructions
2.1.1 Location Considerations
Care should be taken when locating equipment behind the unit to
ensure that AC power wiring, PLC output modules, contactors, starters
and relays, and any other source of electrical interference are located
away from the back of the unit.
Particular note should be taken to the position of variable speed drives
and switching power supplies. Their input and load cables should be
screened to a central star earth point.
2.1.2 Making a NEMA-4 Mounting
Panel Details The unit can be mounted into panels with a depth of
4”(105mm). It is recommended that the unit be
mounted on the front panel of a steel enclosure,
through an appropriate opening*. Allow a clearance of
1”(25mm) around the sides of the unit for mounting
hardware. Allow clearance for cable connections to
the back of the unit. Unit depth may vary according to
cable type used. Typically, plan a depth to
accommodate at least 4”(105mm) behind the panel.
NEMA-4
Mounting
Put the unit through the panel cut out. Slide the
clamps into the 6 holes provided around the case.
Tighten the clamping screws in an even pattern until
the unit is secured in the panel.
Caution! Do not over tighten mounting clamps!
Note: Specifications Note:
To seal to NEMA-4 specifications, all supplied
mounting clamps must be used and panel cannot flex
more than 0.010”.

2.1.3 Environmental Considerations
 The GOT-2770S are to be used indoors as built in displays. Make
sure that the displays are installed correctly and that the
operating limits are followed (See Specifications).
 Do not operate the unit in areas subject to explosion hazards due
to flammable gases, vapors or dusts.
 The unit should not be installed where fast temperature variations
and/or high humidity are present. This will cause condensation of
water in the device.
 Do not install these terminals in environments where have
inflammable gases.

GOT-2770S User’s Manual
2.2.1 Power Requirements
Power The GOT-2770S can be powered by DC power only.
The specified voltage range is +21 to 25 Volts DC.
This insures compatibility with most controller DC
systems. The power conditioning circuitry inside the
unit is accomplished by a switching power supply.
The peak starting current can be as high as 700mA.
Fusing
Requirements
If the display does not come on within 2 seconds of
power up, remove power. An internal fuse will
prevent damage if the polarity of the DC power is
incorrect. Check wiring to insure proper connections
and try to power up again.
Caution
High Voltage
An Internal fuse will prevent damage for over voltage
condition however it isn’t guaranteed.
DC voltage sources should provide proper isolation
from main AC power and similar hazards.
Caution
Emergency
Stop
A Hard-wired EMERGENCY STOP should be fitted
in any system using a GOT-2770S to comply with
ICS Safety Recommendations.
Caution
Supply Voltage
Condition
Do not power the GOT-2770S and inductive DC
loads, or input circuitry to the controller, with the
same power supply. Note: The 24 VDC output from
some controllers may not have enough current to
power the GOT-2770S.
Caution
Wire Routing
Wire lengths should be minimized (Maximum 1600’
(500 m) shielded, 1000’ (300 m) unshielded).
Wires should be run in pairs with a neutral or
common paired with a hot or signal line.
If wiring is to be exposed to lightning or surges, use
appropriate surge suppression devices.
Keep AC, high energy, and rapidly switching DC
wiring separate from signal wires.
Equip ungrounded DC supplies with a resistor and

capacitor in parallel to earth ground. This provides a
path for static and high frequency dissipation.
Typical values to use are 1MOhm and 4700pF.
Connection To make a connection, strip about 3/8” of insulation
off the end of the wire, turn the connector screw
counterclockwise until the gap is wide open, insert
the wire all the way in, and turn the screw clockwise
until it’s tight.
Connect positive DC line to the ‘+24V’ terminal and
the DC ground to the ‘GND‘ terminal.
FUSE Replacement:
The fuse use on GOT-2770S is:

Rating: 1A
Size: 5x20mm
Warning:
1. Make sure the power off before replace the fuse.
2. Do not replace the fuse with a different rating fuse.

GOT-2770S User’s Manual
2.2.2 Grounding Requirements
Chassis ground must be used. DC ground is not directly coupled to
Earth ground internally. It is preferable not to ground DC negative
return to chassis ground as poor site earths can introduce noise into a
system, but if necessary an earth connection should be made, from the
power supply return point to the central star earth point. Ground
conductors should be as short and as large in size as possible. The
conductors must always be large enough to carry the maximum short
circuit current of the path being considered. Ground conductors should
be connected to a tree from a central star earth ground point. This
ensures that no ground conductor carries current from any other
branch.
2.2.3 CE Requirements
To make an GOT-2770S comply with EMC directives, and to reduce
susceptibility to electrical interference, a separate #14 AWG ground
wire should be taken to the chassis ground terminal of the power
connector. This ground connection should be run directly to the central
star earth connection point (as recommended in most Installation
Instructions).

2.2.4 Safety Guidelines
This section presents recommended installation practices, and
procedures. Since no two applications are identical, these
recommendations should be considered as guidelines.
Hardware Considerations WARNING!
The system designer should be aware that devices in Controller
systems could fail and thereby create an unsafe condition.
Furthermore, electrical interference in an operator interface, such as a
GOT-2770S, can lead to equipment start-up, which could result in
property damage and/or physical injury to the equipment operator.
If you, or your company, use any programmable control systems that
require an operator or attendant, you should be aware that this
potential safety hazard exists and take appropriate precautions.
Although the specific design steps depend on your particular
application, the following precautions generally apply to installation of
solid-state programmable control devices. In addition, these
precautions conform to the guidelines for installation of Controllers as
recommended in the NEMA ICS 3-304 Control Standards.
Programming Considerations
To conform with ICS Safety Recommendations, checks should be
placed in the controller to ensure that all writable registers that control
critical parts of plant or machinery have limit checks built into the
program, with an out-of-limit safe shut down procedure to ensure
safety of personnel.
Installation Instructions 11

GOT-2770S User’s Manual
ICS 3-304.81 Safety Recommendations:
Consideration should be given to the use of an emergency stop
function, which is independent of the programmable controller.
Where the operator is exposed to the machinery, such as in loading or
unloading a machine tool, or where the machine cycles automatically,
consideration should be given to the use of an electromechanical
override or other redundant means, independent of the programmable
controller, for starting and interrupting the cycle.
If provision is required for changing programs while the equipment is in
operation, consideration should be given to the use of locks or other
means of assuring that only authorized personnel can make such
changes.
These recommendations are intended as safeguards against the
failure of critical components and the effects of such failures or the
inadvertent errors that might be introduced if programs are changed
while the equipment is in operation. *
