CAUTION!
The test tap is not self-grounding!
The bushing can be destroyed if the test tap is not grounded. Because the capacitance (C
is usually relatively small, the test tap must never be open-circuited when applying a
voltage to the bushing. It must always be grounded or connected to an external impedance.
CAUTION!
Do not energize the bushing without the cover or a test adapter installed. The cover
connects the outermost conductive foil to ground and will prevent damage to the bushing.
CAUTION!
Make sure that the cover is correctly installed with the O-ring in place, when the bushing is
not in use. The purpose is to prevent dust and water from entering the tap.
