Additional requirements include:
• All AC mains and supply conductors to power distribution boxes for the rack-mounted system
must be enclosed in a metal conduit or raceway when specified by local, national, or other
applicable government codes and regulations.
• Ensure that the voltage and frequency of your power source match the voltage and frequency
inscribed on the equipment's electrical rating label.
