Installation Considerations
Our products have been designed and tested for operation in the most demanding industrial environments.
Modern solid-state industrial controls are complex electronic equipment that operate at low levels of voltage and
current, co-existing with components that operate at much higher levels of power. The difference in operating
power characteristics between the high and low power control devices creates the possibility of unwanted signals
being generated, thus causing interference. The interference, which is a by-product of electrical noise, is not
present at all times. However, if it appears at random and for brief periods of time, it can cause disruptions and
errors in the operation of a control system.
Enhancement of a system's noise level immunity and its tolerance to other environmental hazards can be
accomplished by following proper system installation guidelines. The recommendations are of a general nature
and constitute good industrial installation practice.
