magnified view of this area on the Mother Board is shown in Figure 3-13, below. TB1 is for
battery connection. TB1 has a 24VDC, 0.5A, power limited, auxiliary power source. Calculate
proper backup battery requirements using Section 3-8 – Battery Care and Backup Battery
Calculations.(Page 3-19). Section 3-9 on Page 3-21 is the AC and battery installation
procedures.
