Figure 21: DC Power Source Cabling Scheme for a Single DC Power Module
The color coding of the source DC power cable leads depends on the color coding of the site DC power source.
Because there is no color code standard for source DC wiring, be sure that power source cables are connected
to the power modules using the proper positive (+) and negative (–) polarity:
• In some cases, the source DC cable leads might have a positive (+) or a negative (–) label. This is a
relatively safe indication of the polarity, but you must also verify the polarity by measuring the voltage
between the DC cable leads . Be sure that the positive (+) and negative (–) cable leads match the positive
(+) and negative (–) labels on the power module when making the measurement.
•
Green (or green and yellow) cable typically indicates that it is a ground cable.
