Wiring the power shelf
Once the power shelf has been installed and firmly secured proceed with the wiring.
CAUTION
The power shelf wiring should be installed by qualified personnel and in accordance with the local electrical codes.
DANGER
Input voltage to the rectifier and the power shelf is at a hazardous potential. Ensure that the power switch is OFF at the AC service panel working on the power shelf. Hazardous voltages may still be present at the terminals even if the rectifiers are OFF. Use a voltmeter to verify the absence of voltage.
DANGER
Improper wiring can cause personal injury and equipment damage. Verify the proper polarity of the battery leads before connecting them to the power shelf, and clearly identify the positive and negative leads.
