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
