GHT-118
The GHT-118 High Voltage / Ground Bond Adapter Box is an optional accessory
of the GPT-9000 Series Electrical Safety Tester aimed at providing a convenient
way to connect the DUT’s AC line socket for the AC withstanding, DC
withstanding, Insulation Resistance and Ground Bond tests. Among the
GPT-9000 Series Electrical Safety Tester, the Ground Bond testing function is
only available on the GPT-9804 and the GPT-9904.
Consideration
Warning
The GPT-9000 series Electrical Safety Testers operate at up
to 5kVAC and 6kVDC. To prevent electrical shock, the
grounding wire of the adapter box (green/yellow wire)
must be connected to the ground connector of the GPT-9000
rear panel. Please also make sure that the GPT-9000 is
properly grounded via its AC line input. Please refer to the
GPT-9000 User Manual for more information regarding
safety and the earth ground connection.
