Wiring Precautions
WARNING
Before Wiring
• Ground the instrument before connecting the instrument to the target device.
The power cord that comes with the instrument is a three-prong type power
cord. Insert the power cord into a grounded three-prong outlet.
• Be sure to turn OFF the GS820 output when connecting the DUT.
Wiring
• Only use lead wires whose conductive parts are covered for connecting to the
output terminals. Exposed conductive parts can lead to electric shock.
• Do not use lead wires whose conductive parts are exposed due to tears in the
insulation or broken cables as they may lead to a short circuit or electric shock.
• Do not connect a voltage source in voltage source mode or a current source in
current source mode. An incorrect connection may damage the GS820.
• Do not connect a load that exceeds the maximum output indicated below across
the OUTPUT Hi and OUTPUT Lo or across the SENSE Hi and SENSE Lo
terminals.

• The maximum allowable voltage between the case and each terminal is ±250
Vpeak. Applying a voltage exceeding this value can damage the GS820.
• Keep the voltage that is generated across OUTPUT Hi and SENSE Hi and
across OUTPUT Lo and SENSE Lo less than or equal to ±0.5 Vpeak.
• When making a four-terminal connection, be careful that the connection to
the SENSE terminal does not get cut. If the voltage is not sensed correctly,
abnormal voltage will appear across the OUTPUT Hi and OUTPUT Lo terminals.
• When making a two-terminal connection, use the OUTPUT terminals. If the
SENSE terminals are used, the current flows through the SENSE line prohibiting
the GS820 from generating correcting and causing damage.
