2.5.1 Sources of Electrical Interference
Ensure that the HI 6200 is protected from sources of electrical interference. The following
table provides examples of electrical interference.
Potential Source
Description
Wall outlets
Power outlets for building maintenance and janitorial equipment, such as
vacuum cleaners and floor buffers, must be wired from circuit breakers on a
power panel separate from the computer system panel. The ground wires from
these outlets must connect to the normal building distribution panel and not to
the system ground. If a separate power source and separate ground are not
provided, maintenance and janitorial equipment can induce electrical noise
that can affect operation of the HI 6200. Your electrician can verify whether
maintenance outlets are on separate panels.
Lightning
In geographical areas subject to lightning storms, you may want install
lightning protection for your HI 6200. The principles of lightning protection and
personnel safety are described in the National Fire Protection Association
(NFPA) Handbook.
Electromagnetic interference Electromagnetic interference can cause various problems. The HI 6200 is
designed to reduce its susceptibility to radiated and conducted interference. A
Hardy Process Solutions representative can advise you about common
causes of electromagnetic interference.
