Connector Type The unit is supplied with a 50-foot cable and male connector. The connector is a Russellstoll 200 Amp plug #DS2504MP000/ DF2504FRAB0 . Customer Facility The facility must have the matching receptacle as specified in Figure 5: Russellstoll Service Outlet . The receptacle is a Russellstoll #DF2504FRAB0. Voltage Surges Transient voltage variations caused by external loads must not: • Exceed + 5% • Exceed five cycles duration • Occur more than ten times an hour. Power Source Monitoring (Facility Only) NOTE: Perform a power audit first. A power analyzer should be used to check the proposed Mobile MRI Series facility site power for average line voltage, surges, sags, reclosures, impulses, frequency and microcuts. A period that includes two weekends should be used to simulate several days of normal use. Analysis of the data and site history of any previous power problems with other X-ray systems or computer installations should be reviewed with your power and ground representative. Verify “brown-out” (low voltage) conditions, which may occur during summer months, will not exceed the allowable range. Some analyzer models that are suitable for power monitoring are: • Dranetz Model 658 • Dranetz Model 656A • BMI 3630 • RPM Ground Conductor An insulated ground conductor sized in accordance with National, State, and local codes shall be installed between the facility vault and the MRI System ground bus location in the power distribution unit. Magnetic Shielding The MRI unit is equipped with magnetic shielding. The exclusion zone for cardiac pacemakers, neurostimulators, and other biostimulation devices is recommended at 5 gauss (0.5mT). Signs provided by Siemens, must be posted to alert all who approach the unit of this requirement. The appropriate warning signs are permanently attached to the scan room doors. The 1.0T and 1.5T magnet systems exclusion zone (5) gauss is restricted to within 6” of the exterior walls of the mobile unit. R.F. Shielding The R.F. shield is included with the MRI system and will provide minimum level of attenuation: • 15Mhz – 128Mhz, 90db.
