Choose either of the following two available methods of doing so:
1.
Connect the AC power cord to a three-contact grounded
electrical outlet.
2.
Connect the protective conductor terminal on the rear panel to
the earth ground. Have specialized engineers select,
manufacture, and install cables.To ensure secure connection,
use proper tools.
1.7 Checking Operations
！
WARNING
Use only the interlock jumper to quickly cancel the protection
status.
When using this tester, use the interlock function as much as possible to
ensure a safe operating environment. To use jigs in withstanding voltage or
insulation resistance testing, provide a cover or other means for the DUT to
prevent electric shock by cutting off the output when the cover is opened. It
is also recommended that an enclosure be provided around the operating
area and that output be cut off every time the door is opened.
Before turning on the power, confirm that the allowable voltage range
indicated on the power supply is the same as that indicated on the rear
panel of the tester.
When the power is turned on, the tester lights all LEDs on the front panel
and self-diagnosis is started.
Before starting up the tester, confirm that all LEDs are on to ensure safety.
It is particularly dangerous to start a test when the DANGER lamp is broken.
Note that, in self-diagnosis, even when the DANGER lamp is lighting, no
output or voltage is being generated.

CAUTION
After turning off the POWER switch, wait several seconds
before turning it back on. Turning the POWER switch on/off repeatedly with
insufficient intervals may damage the tester.
