All of the required components shall be mounted in a lockable and secure NEMA 4X enclosure that is wall-mounted on stainless steel mounting brackets located within close proximity to the wetwell and valve vault. The wetwell level indicator, low wetwell level bypass switch, and the alarm indicating lights for the high wetwell level and the low wetwell level shall be mounted on a display board in a NEMA 4X enclosure. The flowmeter (digital LED readout) readout shall also be mounted in the same NEMA 4X enclosure as that of the other instrumentation. For details of the instrumentation enclosure, see Drawings DG-08-04, DG-08-04A, and DG-08-04B. (Design Guideline DG-08 § 16.5, dated August 2006)
