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 the interlock jumper only 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
on. Turning the POWER switch on/off repeatedly with insufficient intervals may damage
the tester.
Checking procedure:
1. Confirm that the allowable voltage range indicated on the power supply is the same as
that indicated on the rear panel.
2. Confirm that the AC power cord is properly connected to the AC LINE connector on
Earth
ground
