Grounding the System
Proper Grounding Practices
Grounding is one of the most important parts of equipment installation. When you properly ground systems
during installation, you reduce or prevent shock hazards, equipment damage due to transients, and data
corruption.

Grounding Recommendations
Electromagnetic Noise Severity
Level
Environment
All lightning protection devices
must be installed in strict
accordance with manufacturer
recommendations. Conductors
carrying lightning current should
be spaced away from power and
data lines in accordance with
applicable recommendations and
codes. Best grounding
recommendations must be closely
followed.
High
Commercial building is subjected
to direct lightning strikes.
For example, some places in the
United States, such as Florida, are
subject to more lightning strikes
than are other areas.
Best grounding recommendations
must be closely followed.
High
Commercial building is located in
an area where lightning storms
frequently occur but is not subject
to direct lightning strikes.
Best grounding recommendations
must be closely followed.
Medium to high
Commercial building contains a
mix of information technology
equipment and industrial
equipment, such as welding.
Determine source and cause of
noise if possible, and mitigate as
closely as possible at the noise
source or reduce coupling from the
noise source to the affected
equipment. Best grounding
recommendations must be closely
followed.
Medium
Existing commercial building is not
subject to natural environmental
noise or man made industrial noise.
This building contains a standard
office environment. This
installation has a history of
malfunction due to electromagnetic
noise.
