Installing the Test System
Connecting the test circuit
“DSI1020 test circuits:
two types” (p. 22)
“DSI3020 test circuits:
five types” (p. 23)
Connect this product, the AC power supplies, and the EUT to construct the test circuit.
Connect the wires according to the test circuit connection diagram that corresponds to your
product model.
• When using model DSI1020, you can use two types of test circuits.
See
“DSI1020 test circuits: two types” (p. 22) .
• When using model DSI3020, you can use five types of test circuits.
See
“DSI3020 test circuits: five types” (p. 23) .
Select the test circuit appropriate for your EUT.
Connecting wires
 Terminal screw sizes
• I/O terminal screw size of the DSI (this product): M6
• Output terminal screw sizes of AC power supplies
See
WARNING
Risk of electric shock.
• Be sure to attach the terminal cover of this product. High voltage will be applied to the
terminals.
• Before you connect cables to the AC power supplies’ OUTPUT terminal blocks, be
sure to turn the POWER switch off, and then shut off the power supply from the
switchboard.
• Be sure to ground the product to prevent electric shock.
• Never connect the INPUT terminal block of this product to the AC line. The internal
circuit of this product is not designed to be connected to the AC line.
• Fasten the terminal screws securely. Loose screws are dangerous because the
wires may come loose or the connection may heat up.
• The G terminal in the connect diagrams is not the protective conductor terminal (the main
ground terminal to be connected to an external protective conductor).
This product does not include wires for connecting devices or crimping terminals for the
wires. Check the screw sizes of the I/O terminals of each device, and use appropriate single-
core wires and crimping terminals. We recommend that you use wires with a nominal cross-
sectional area of at least 8 mm

(AWG8).
