When using the GP477R-EG11, GP577R-TC11, 577R-SC11 models, please pay
special attention to the following items.
If the supplied voltage exceeds the
GP unit's range, connect a voltage
transformer.
Chapter 2, "Speci-
fications", for the allowable
voltage range.
For between the line and ground,
select a power supply that is low
in noise. If there is an excess
amount of noise, connect a noise
reducing transformer.
Use Voltage and Noise Reducing
transformers with capacities
exceeding 100VA.
When supplying power to the GP
unit, please separate the input/
output and operation unit lines as
shown in the figure.
To increase the noise resistance
quality of the power cable, simply
twist each power wire before
attaching the Ring Terminal.
The power supply cable must not
be bundled or positioned close to
main circuit lines (high voltage,
high current), or input/output
signal lines.
