Isolated 120/240 VAC plant power unit.3. 12 VDC secondary (standby) power supply.4. Static power converter to accommodate 16 to 35 VDC secondary power supply (compatible with 24 V,32 V battery).5. 12V lead-acid battery and charger.2-5.1POWERCONNECTIONS. External power connections to power terminals for CD800/830 seriesmodels are designated in Table 2-1 and Figures 2-11 through 2-15.Power transformers are factory-wired for 120 VAC operation, as shown in Figure 2-10 diagram A. Transformerwires may be reconnected for 240 VAC operation, if required, as shown in diagram B.NOTE: Model CD800X third wire ground (green) is connected to terminal board terminal labeled "GND:' ModelCD800P third wire ground (green) is connected to AC power terminal strip, terminal "G."Figure 2-10.
