Isolated
grounding (IG) is a technique often used with sensitive electronic equipment
to reduce common mode noise. IG insulates the grounding of the sensitive load
equipment from the conduit and raceway grounding system and controls the connection
to the power grounding system. Thus, ground potential shifts due to stray
ground currents flowing in the conduit system are eliminated, and raceways
and conduits provide EMI/RFI shielding. IG is sometimes misinterpreted to
mean a separate "isolated" ground for the sensitive load, and configurations
based on this interpretation are usually unsafe and in conflict with National
Electrical Code requirements. If currents induced in the isolated load equipment
ground are allowed to flow over data, communication, and control cabling,
IG wiring may actually contribute to inductively coupled common mode noise
when applied to circuits that have interconnected load equipment.

Whether you own a home-based business, or a fully networked system, your data is critical, and your power supply is subject to fluctuations in quality and voltage. An Uninterrutible Power Supply not only protects your equipment from dangerous surges, it can also "clean" the power, ensuring compatibility with all systems. | ![]() |
