ive assembly to assureensure optimum availability of the emergency generators on demand. g. Except for sensors and other equipment that must be mounted directly on the engine or associated piping, the controls and monitoring instruments are installed on a free-standing, floor-mounted panel located on a vibration-free floor area. If the floor is not vibration free, the panel should be equipped with vibration mounts. In the event that the instruments and controls cannot be removed from the engine skid, due to plant design, the controls and instrumentation should be environmentally qualified for vibration service. Until the environmental qualification of the components is completed, the applicant has implemented an augmented inspection, test, and calibration program. Verify that this program has been adequately described in the SAR. 5. Identification of Cables, Raceways, and Terminal Equipment The identification scheme used for safety-related cables, raceways, and terminal equipment in the plant and internal wiring in the control boards is reviewed to see that it is consistent with IEEE Std 384 as augmented by Regulatory Guide 1.75. This includes the criteria for differentiating between (a) safety-related cables, raceways, and terminal equipment of different channels or divisions; (b) nonsafety-related cable which is run in safety raceways; (c) nonsafety-related cable which is not associated physically with any safety division; and (d) safety-related cables, raceways, and terminal equipment of one unit with respect to the other units at a multi-unit site. 6. Vital SupportingAuxiliary Supporting Systems/Features114 The PSBEELB will review those auxiliary supporting systems identified as 115 116 being vital to the operation of safety-related loads and systems. IEEE Std 603, as endorsed by Regulatory Guide 1.153, provides criteria used to evaluate all aspects of the instrumentation, control, and electrical portions of auxiliary supporting systems and features, including
