POWER SUPPLY CONNECTIONS

TM 10-6665-297-13&P 2-5 POWER SUPPLY CONNECTIONS. CD800/830 and CD832 Series Control Modules may utilize the following external power sources: 1. 120/240 VAC external power service line. 2. 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. 2-5.1 POWER CONNECTIONS. External power connections to power terminals for CD800/830 series models 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. Transformer wires 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:' Model CD800P third wire ground (green) is connected to AC power terminal strip, terminal "G."

Both AC and DC power may be connected simultaneously, so that DC power will be automatically supplied should the main AC power input be interrupted. The standby power supply should not operate from the same generator, converter, or other device that provides the primary power supply. DC + and - power connections to the control module or module assembly terminal board are marked 12 V, and + and -, or VDC, +12 an -, depending on the particular model to be installed (CD800P/CD802P: terminals TB-2, 6(+) and 7(-)). 2-5.3 STATIC POWER CONVERTER.
