Hazardous voltages are present at the input of power systems. The DC output from rec-
tifiers and batteries, though not dangerous in voltage, has a high short-circuit current
capacity that may cause severe burns and electrical arcing.
• Before working with any live battery or power system, follow these precautions:
a. Remove all metallic jewelry, such as watches, rings, metal rimmed glasses, or necklaces.
b. Wear safety glasses with side shields at all times during the installation.
