Safety Precautions - QuadTech Guardian 6100 Plus Instruction Manual

The Guardian 6100 Plus Electrical Safety Analyzer can provide an output voltage as high
as 6000VDC (5000VAC) to the external device under test (DUT). Although the
Guardian unit is designed with full attention to operator safety, serious hazards could
occur if the instrument is used improperly and these safety instructions are not followed.

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
DANGER light is ON.
Before turning on the Guardian unit, make sure there is no device (DUT) or
fixture connected to the test leads.
After each test, press the
voltage being applied to the output terminals.
When the red DANGER

Before touching the test lead wires or output terminals make sure :
a) The red [STOP] button has been pressed
b) The red DANGER LED is OFF.
In the case of an emergency, turn OFF the POWER switch using a "hot stick" and
disconnect the AC power cord from the wall. DO NOT TOUCH THE Guardian
6100 Plus INSTRUMENT.
Position the equipment so it is easy to disconnect.Always disconnect by means of
the power plug or power connector.

When the Guardian 6100 Plus instrument is remotely controlled, be extremely
careful. The High Voltage Output is being turned On/Off with an external signal.
