UL 698A Intrinsically Safe Control Panels
Along with building NEMA 7 (explosion proof) panels,
Hydro-Flo also manufactures UL 698A certified panels. UL 698A is the
UL specification for the design and fabrication of
intrinsically safe control panels. We have listed the table of
contents from UL-698A (see below). All of the items covered by
UL-698A are supplied in addition to the items covered by the standard UL-508A
specification.
Any time you have to control a process located
in a hazardous area, Intrinsically safe control panels
are always the preferred method of construction and installation.
These hazardous areas
are often contaminated with a variety of flammable gases and vapors.
Locating the control panel outside the classified area and
installing intrinsically safe barriers (along with other safeguards)
the panel can be classified as intrinsically safe.
If, due to process or operator requirements, the control system must be installed within the classified
area, a NEMA 7
explosion proof panel will be required. |
