Appendix B-Contains simulators and settings that may be used to assess the performance of the NIBP module. Maintenance Test Checklist-Contains a blank checklist that can be copied and used to record the results of device maintenance tests.
Safety Considerations The following section describes general warnings and safety considerations for operators and patients. Service technicians should review the safety considerations prior to servicing any equipment and read the manual carefully before attempting to disassemble the unit. Only qualified personnel should service the X Series unit. Federal (U.S.A.) law restricts this unit for use by or on the order of a physician. Safety and effectiveness data submitted by ZOLL Medical Corporation to the Food and Drug Administration (FDA) under section 510(K) of the Medical Device Act to obtain approval to market is based upon the use of ZOLL accessories such as disposable electrodes, patient cables and batteries. The use of external pacing/defibrillation electrodes and adapter units from sources other than ZOLL is not recommended. ZOLL makes no representations or warranties regarding the performance or effectiveness of its products when used in conjunction with pacing/defibrillation electrodes and adapter units from other sources. If unit failure is attributable to pacing/defibrillation electrodes or adapter units not manufactured by ZOLL, this may void ZOLL's warranty. Only qualified personnel should disassemble the X Series unit.
WARNING!
This unit can generate up to 2775 volts with sufficient current to cause lethal shocks. All persons near the equipment must be warned to “STAND CLEAR” prior to discharging the defibrillator. Do not discharge the unit’s internal defibrillator energy more than three times in one minute or damage to the unit may result. Do not discharge a battery pack except in a ZOLL SurePowerTM Charging Station. Do not use the X Series in the presence of flammable agents (such as gasoline), oxygen-rich atmospheres, or flammable anesthetics. Using the unit near the site of a gasoline spill may cause an explosion. Do not use the unit near or within puddles of water.
Additional Reference Material In addition to this guide, there is a X Series Operator’s Guide(REF: 9650-002355-01) which is a comprehensive reference work that describes all the user tasks needed to operate the X Series.

Maintenance Tests
2.0Leakage Current Test Before You Begin ZOLL X Series® and X Series® Advanced defibrillators have been certified as Class 1 ME externally powered per IEC/EN 60601-1 Standards. The device meets the Class 1 standard when operating on battery as the device is internally powered, and again when operating on AC due to the presence of a protective earth connection. The design of X Series and X Series Advanced devices complies with IEC standards, which allow for various methods of protection. Subclause 8.6 of IEC 60601-1 states the following: "Typically, metal ACCESSIBLE PARTS of CLASS I A1E EQUIPMENT are PROTECTIVELY EARTHED. However, they could be separated by other MEANS OF PROTECTION, in accordance with 8.5." Subclause 8.5.1 details the following example: "PATIENT CONNECTIONS and other ACCESSIBLE PARIS are separated from parts different from earth potential by DOUBLE or REINFORCED INSULATION" The X Series and X Series Advanced comply with subclause 8.5.1 as the external power supply is double insulated, and therefore provides protection to the entire rest of the system. Further, an isolation transformer within the external power supply also provides a reduction in voltage from the AC input to 14.5Vdc. The power supply itself remains Class 1 due to the presence of a protective earth; double insulation alone does not mandate that the adapter be classified as Class 2 by the IEC. Per the standards, a protective earth connection is not required to be carried through to the chassis. Any exposed metal components on the chassis, which carry through the power supply, are functional grounds only and are not to be considered protective. As the chassis does not require a protective earth due to the electrical system design, measuring protective Earth resistance is Not Applicable per the standard.
