Pre-Installation Considerations
Introduction
Installation of the controller consists of mounting and wiring the controller according to the guidelines
given in this section. The controller is industrial control equipment that must be panel mounted within an
enclosure. The wiring terminals must be enclosed within the enclosure.
Read the pre-installation information, check the model number interpretation [Controller model number
(page 21)], and become familiar with your model selections, then proceed with installation.
While the UMC800 has been designed for use in most industrial environments, there are certain
requirements that should be considered regarding installation and wiring to ensure optimum performance.
Many of the problems associated with electronic control equipment can be traced to the primary ac power
system. Disturbance, such as electrical noise, power interruptions, and lightning, must be factored into the
planning of the primary power system so the control equipment will perform satisfactorily and
continuously.
In addition to the precaution of the separation of signal and power wiring in separate conduits, this section
suggests some other measures that can be taken to minimize the effects of electromagnetic interference
(EMI) and radio frequency interference (RFI), voltage surges and static electricity.
