Preparation
Preparing for Connecting a DUT
This product does not include cables for connecting a DUT. Prepare connectors and cables according to
the DUT. You need to prepare as many connectors and cables as the channels you use in tests.

Cable current capacity
Cables will not be damaged even if the DUT is short-circuited when you use the ones having a capacity
that meets or exceeds the rated output current. The cables to be used must have sufficient current
capacities for the rated output current of this product. Using the following table as a reference, select
wiring whose nominal cross-sectional area is as thick as possible.
 Dependence of the cables’ allowable current on the insulation’s maximum allowable
temperature
A cable’s temperature is determined by the resistive loss based on the current, the ambient temperature,
and the cable’s external thermal resistance. The following table shows the current capacity of heat-
resistant vinyl cables that have a maximum allowable temperature of 60 °C when one of the cables is
separated and stretched out horizontally in air in an ambient temperature of 30 °C. The current must be
reduced under certain conditions, such as when vinyl cables that have a low heat resistance are used,
when the ambient temperature is 30 °C or greater, or when cables are bundled together and little heat is
radiated.
WARNING Risk of fire.
• Use output cables whose capacity is adequate for the product’s rated output
current.
• The output terminal and its surrounding area become very hot. Use cables whose
covers have an allowable temperature of 85 °C or higher.
Risk of electric shock.
• Use output cables with a voltage rating that meets or exceeds the product’s
isolation voltage. For details on the product’s isolation voltage, see “General
Specifications”
(p.45) .
• If the DUT will be subject to high temperature, such as by placing it in a temperature
chamber, pay attention to the allowable temperature of the output cable. If the heat
resistance is insufficient, the DUT will be in a dangerous situation due to poor
insulation, increased contact resistance, and so on.
CAUTION
• Use output cables with a wire diameter that is appropriate for the amount of current being
used and with sturdy, flame-resistant insulation.
• Twist the cables (+ and -) to achieve stable operation, reduce the influence of noise, and
prevent a malfunction. Do not let the cables get tangled or crossed.
