Safety Precautions
Operate the Guardian 6100 Plus unit with its chassis connected to earth ground.
The instrument is shipped with a three-prong power cord to provide this
connection to ground. This power cord should only be plugged in to a receptacle
that provides earth ground. Serious injury can result if the Guardian 6100 Plus is
not connected to earth ground.
Tightly connect cable(s) to the (black) DRIVE- terminal. If this is not done, the
DUT's casing can be charged to the high voltage test level and serious injury or
electrical shock hazards could result if the DUT is touched.
For High Current Ground Bond Testing, make the connection to the DRIVE+ and
DRIVE- terminals with the spade lug behind the nut. Use the Bushing Driver
Tool included to secure the nut as shown in Figure COI-2.
Never touch the metal of the High Voltage probe directly. Touch only the
insulated parts of the lead(s).
Never touch the test leads, test fixure or DUT in any manner (this includes
insulation on all wires and clips) when the high voltage is applied and the red
