2. Connection with external power
supply
To avoid an electric shock, prior to
connecting the GP3000H’s power cord
terminals to the power terminal block,
confirm that the GP3000H’s power
supply is completely turned OFF, via a
breaker, or similar unit.
Any other power level can damage both
the GP3000H and the power supply.
When the FG terminal is connected, be
sure the wire is grounded.
• To improve noise resistance, be sure to use
the Common Mode Filter included with
this product.
• The common mode filter uses a metal
chassis. When installing the common
mode filter on the panel:
- IF you can ground FG, the provided FG
wire is not required.
- IF you cannot ground FG, use the
provided FG wire and the M3 screw to
fasten the common mode filter and
provided FG wire.
Power Supply Cautions
• Input and Output signal lines must be
separated from the power control cables
for operational circuits.
• The GP3000H’s power supply cord should
not be bundled with or kept close to main
circuit lines (high voltage, high current), or
input/output signal lines.
• To improve noise resistance, make the
power cord as short as possible.
• If the supplied voltage exceeds the
GP3000H’s range, connect a voltage
transformer.
• Between the line and the ground, be sure to
use a low noise power supply. If there is an
excess amount of noise, connect a noise
reducing transformer.
• Use voltage and noise reducing
transformers with capacities exceeding
the GP3000H’s Power Consumption
value.
• Connect a surge absorber to handle
power surges.
• Be sure to ground the surge absorber
(E1) separately from the GP2000H
Conversion Adapter (E2). Select a
surge absorber that has a maximum
circuit voltage greater than that of the
peak voltage of the power supply.
