Additionally, a single supply of sufficient amperage may be shared among multiple mainframes that are
connected to a common power bus - provided that the total current can be supplied while meeting the
voltage specification at the power bus terminals at the rear of the Agilent MCCD.
NOTE: If the external dc power source has an overvoltage protection circuit, it must be set
higher than 30 volts to avoid the possibility of shutting itself down during the discharge
cycle.
