Please pay special attention to the following instructions when connecting the power cord
terminals to the Xpanel unit.
• If the power supply voltage exceeds the GP's specified range, connect a voltage
transformer.
• Between the line and the ground, be sure to use a low noise power supply. If there is still
an excessive amount of noise, connect a noise reducing transformer.
• The power supply cord should not be bundled with or kept close to main circuit lines (high
voltage, high current), or input/output signal lines.
• Connect a surge absorber to handle power surges.
• To reduce noise, make the power cord as short as possible.
When grounding to the rear face FG terminal of the Xpanel, (on the Power Input Terminal
Block), be sure to create an exclusive ground.
• Inside the Xpanel unit, the SG (Signal Ground) and FG (Frame Ground) terminals are
connected to each other.
• When connecting an external device to the Xpanel with the SG terminal, ensure that no
short-circuit loop is created when you setup the system.
