Power Supply Precautions

Be aware of the following items when attaching the power cord terminals to the GP's

power terminal block.

•  When operating the GP where large power fluctuations will occur, install a constant

voltage transformer.

•  When attaching an expansion unit to the GP, be sure to read the expansion unit's

Installation Instructions.

•  To reduce wire-to-wire or wire-to-earth noise as much possible, use a low-noise

power supply. If noise is excessive, use a Noise Reducing Transformer.

•  Be sure to separate all GP power, I/O unit and Operation unit lines.
•  To increase the noise resistance of the power wires, twist the ends before attaching the

Ring Terminal.

•  Do not bundle or position the GP's power cord near main circuit lines (high voltage,

strong current), or I/O signal lines.

•  To prevent damage from lightning, be sure to install a lightning surge absorber
•  To minimize line noise, make the GP's power cord as short as possible.

Grounding Precautions

•  When attaching a wire to the GP's rear face FG terminal, (on the Power Input Terminal

Block), be sure to create an exclusive ground.

*1

•  Inside the GP377R-TC-24V unit, SG(Signal Ground) and FG(Frame Ground) termi-

nals are connected to each other.

•  When attaching an expansion unit to the GP, be sure to read the expansion unit's

Installation Instructions.

I/O (Input/Output) Signal Line Precautions

  All GP Input and Output signal lines must be separated from all operating circuit

(power) cables.

  If this is not possible, use a shielded cable and ground the shield.

*1  Use a grounding resistance of 100

, a wire of 2mm

2

 or thicker, or your country's

applicable standard.

The GP-377R-TC11-24V unit’s backlight cannot be changed by the User. When backlight
change becomes necessary, please contact your local GP distributor for service.
When the GP-377R-TC11-24V unit's backlight burns out, the unit’s orange colored status
LED will light. If the “USE TOPUCHPANEL AFTER BACKLIGHT BURNOUT” is previ-
ously set to “NO”, the GP’s touch panel will now become disabled.
The GP uses a long-life type CFL type backlight, however, the lifetime of each user’s back-
light will depend on the actual usage conditions.
The average GP’s backlight lifetime (i.e. until the backlight’s brightness dims to half of the
original level) should be 50,000 hours (approx. 5.7 years), when continuously lit with appro-
priate voltage, used in the room temperature.
