Installation
of
A cable that provides both types of shielding is preferred, however, a braided shield alone will usually provide adequate protection. To reduce chances of ground loops, shields should be grounded only on one end, preferably at the signal source.
Selecting An Enclosure
The Emerson Motion Control 525 PMC is designed for the industrial environment. However, no sophisticated electronic system can tolerate certain atmospheric contaminants such as moisture, oils, conductive dust, chemical contaminants and metallic particles. Therefore, if the 525 PMC is going to be subjected to this type of environment, it must be back mounted verticality in a metal NEMA type 12 enclosure. Proper ventilation and filtering must also be provided. If the equipment environment is above 80 F, cooling should be considered.
Enclosure Size
The size of the enclosure will determine how long it takes the temperature inside to rise. It will also affect the thermal transfer of the enclosure. Normally, the larger the enclosure the better the thermal transfer. Thermal transfer is also affected by venting, forced air cooling, and the enclosure material.
