This type of notice is meant to inform the operator of useful information.
Support Pad Requirements It is recommended that non- ferrous reinforcement materials be used for pad reinforcement. Siemens must approve plans for pad construction.
The following is a list of recommendations and requirements for a concrete support pad. However, due to varying site conditions, the actual pad design should be prepared by an appropriately licensed structural or architectural engineer. Trailer Weight The weight of the trailer should be considered in the design of the support and service pads. The overall weight of the trailer is approximately 60,000 lbs. The weight on the rear axles is approximately 40,000 lbs. The weight on the King Pin is approximately 20,000 lbs. Recommended Service Pad and Support Pad Requirements A service pad is recommended to provide adequate service access. The recommended size of the pad is 60’ x 18’, For details please see Figure 1 Plan View and Pad Layout. Support Pad Depth Recommendations for the width and length of the pad are given above. Based upon existing site conditions, the depth should be determined by a local contractor. It is recommended that non-ferrous reinforcement materials be used for pad reinforcement. Siemens must approve plans for pad construction.

Support Pad Levelness The support pad must be level to ensure proper operation of the MRI system. The pad must not exceed .125” deviation in 10’-0”. If the minimum support pads are selected, rather than the recommended single pad, they must also meet this specification. Vehicle Access A firm, level surface is required around the mobile unit to provide access to the tractor/trailer, aid with patient handling, servicing the unit, and delivering of cryogens. Steel Reinforced Concrete Pad Nonferrous reinforcement materials are recommended. If ferrous materials are used, contact the Siemens for the maximum weight allowed per foot. Recommended Attachment to Facility An inflatable air bag or soft seal is recommended at the point of connection from the unit to the facility. Fixed or solid connections may hinder imaging quality. Contact AMST or the local Siemens representative prior to construction if the proposed connection varies from the recommended. Exclusion Zone The helium gas must be allowed to vent, unrestricted, to a non-accessible area, allowing the helium gas to dissipate.
To avoid the risk of injury and cold burns and the possibility of asphyxiation, access to the quench tube must be restricted by 10’ to each side and below, and 20’ vertically above the exit vent. Failure to do so could result in severe personal injury or death. Vehicle Movement
The MRI is very sensitive to vibration and moving metal. Consequently, all vehicle traffic shall be kept as far away as possible from the pad. Moving ferrous materials having the listed masses should be limited to areas as described in Siemens site planning publication. Contact Siemens to obtain the latest version. Vibration / Foundation Design Please contact Siemens for the latest system specific vibration requirements. Swing Clearance Note Please verify the actual dimensions of the rearmost projections on the cab of your tractor to the centerline of tandem suspension or centerline of the fifth wheel plate on your tractor. Refer to Figure 7 Turning Requirements for proper tractor sizing information.

Customer Power Requirements It is the operators’ responsibility to verify that the shore power receptacle is of the same type and voltage as the connection that is supplied by AMST. Failure to do this can result in injury or death to the operator of the mobile unit as well as irreparable damage to the mobile unit. The standard connector for the unit is a Russellstoll #DS2504 MP000/ DF2504FRAB0 . If an existing site currently implements a different connector or connector configuration, please contact AMST in order to arrange for a compatible power connector before the unit leaves the facility. Lockout/Tagout
A Lockout/Tagout provision in accordance with OSHA Standard 1910.147 is required. The facility shore power disconnect device must be located within 40’- 0” of the unit and must provide for an effective lockout/tagout to facilitate safe service and maintenance of the unit. Electrical Service One electrical power source receptacle is required for operation of the MRI system. It must be capable of providing 480 Volt A.C., 3 Phase, 112.5 KVA, fused at 150 Amps or 157.6 KVA, fused at 200 Amps (depending on modality’s specifications). One source provides power to the medical system and the trailer systems, such as lighting and air conditioning. Manufacturer System Power Amps Neutral Required Connection Type

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.
