Installation 15088: J 10/22/99
Step 1
Position the Main Power Supply over the
support bracket in the lower left corner of
the cabinet and carefully push the supply
down until it engages the bracket securely.
Step 2
Secure the Main Power Supply to the
cabinet with the two self-tapping
screws provided.
Figure 3.2-1 Mount the Main Power Supply
Figure 3.2-1 depicts the two-step procedure of mounting the main power supply.
2. Measure time of load.
a. Take a fully charged battery and install the load resistor across the terminals.
b. Measure the voltage across the battery for a period of 20 hours. If during the test the
terminal voltage drops below the minimum acceptable levels (10.2 VDC for a 12 volt
battery and 20.4 VDC for a 24 volt battery), note the number of hours that have elapsed
when the battery voltage drops below its minimum operational level.
3. Calculate the battery capacity.
CAPACITY = TIME x LOAD where:
TIME (in hours) is equal to the measured duration the terminal voltage remained at the
acceptable level and LOAD is equal to the load current value.
If the battery maintained its voltage level above its minimum operational level for 15 hours,
its capacity would be: 15 x 1.25, or 18.75 amp hours.
Conclusion: The battery has only 18.75 amp hour capacity instead of its rated 25 amp hours.
