Protection against defibrillation voltage is however only ensured, if the original SCHILLER patient cable (Part-no.2.400071) is used. Make sure that during ECG recording neither the patient nor the conducting parts of the patient connection or the electrodes (including the neutral electrode) come into contact with other persons or conducting objects (even if these are earthed).
