  System Acceptance 2 MAINS AND PROTECTIVE EARTH CONNECTION OF OPTION L EQUIPMENT Optional equipment Is all equipment that Is not powered via the Power Distribution Definition: Unit of the X-ray system. Purpose: To ensure that optional equipment Is connected In accordance with I EC 60601-1-1 ã Switch OFF the system and the optional equipment. Check that the optional equipment Is connected via an Insulating mains transformer: -Thi~ can be via a built-in insulating mains transformer (e .g .: HaemoSphere), or via a multiple portable socket outlet (MPSO) with insulating mains transformer. Check that the Protective Earth (PE) of the optional equipment is connected to the Protective Conductor Bar (PCB): -This can be checked by measuring the resistance between the PE of the optional equipment and the PCB. The expected value is approximately 0.6 Ohm. -Use a Multimeter, do not use an Earth Bonding Tester.
