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.
