Best grounding recommendations
must be closely followed.
Medium to highCommercial 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.
MediumExisting 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.
Electromagnetic noise problems are
not anticipated, but installing a
grounding system in a new building
is often the least expensive route
and the best way to plan for the
future. Best grounding
recommendations should be
followed as closely as possible.
LowNew commercial building is not
subject to natural environmental
noise or man-made industrial noise.
This building contains a standard
office environment.
Electromagnetic noise problems are
not anticipated, but installing a
grounding system is always
recommended. Best grounding
recommendations should be
followed as much as possible.
LowExisting commercial building is not
subject to natural environmental
noise or man-made industrial noise.
This building contains a standard
office environment.
In all situations, grounding practices must comply with local National Electric Code (NEC) requirements or
local laws and regulations.
Note
Always ensure that all of the modules are completely installed and that the captive installation screws are
fully tightened. In addition, ensure that all I/O cables and power cords are properly seated. These practices
are normal installation practices and must be followed in all installations.
Note
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which can occur when modules or other devices are improperly handled,
results in intermittent or complete failures. Modules consist of printed circuit boards that are fixed in metal
carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier.
