Getting Started
Use your own good judgement and common sense. You must
protect yourself from the effects of lightning.
You must assume that hazardous voltages will be present on
exposed surfaces of this product if it is connected to a source
exposed to lightning. The insulation of this product will not
protect you from these hazardous voltages.
Do not connect this product to any source which might be subject to
the effects of lightning
If thunderstorms or lightning are in your vicinity:
When weather conditions that could lead to lightning activity
exist in your area, you could be at risk of a lightning strike
before the cloud is close enough for you to hear thunder or see
lightning.
When lightning strikes a structure or facility, current travels
through the rebar, concrete, pipes, cables, vent stacks, and
electrical system.
Lightning can induce electric and magnetic fields into structures
and portions of wiring. The length of a conductor affected by the
magnetic field of a lightning strike may exceed two miles.
Be alert and aware of the effects of lightning
When lightning strikes a conductor, which in turn introduces the
current into an area some distance from the ground strike point,
equipment can be damaged and personnel injured if they
become an indirect path in the completion of the ground circuit.
Conductors such as the braided shields of cables or unshielded
wires will have significant transient currents flowing in them in
regions exposed to the electric field effect of lightning.
Induced voltages may cause breakdown of insulation in wiring at
connectors and in electrical components or breakdown of air.
