Notes:
1. The A1 and A2 dc connectors are keyed so that the dc cables are connected to the A1
and A2 connectors in only one way and in opposite orientation from each other. If the dc
cable does not fit the dc connector, flip it 180 degrees and try again. Do not force fit
because you might damage the connectors and short out the power supply.
2. The B1 and B2 dc connectors are keyed so that the dc cables are connected to the B1
and B2 connectors in only one way and in opposite orientation from each other. If the dc
cable does not fit the dc connector, flip it 180 degrees and try again. Do not force fit
because you might damage the connectors and short out the power supply.
Figure 8 on page 12 shows a dc power supply and fan unit and the airflow through
