Power Cord Requirements for AC-Powered Switches and AC Power
Supplies
An AC power cord is not included with the AC power supply.
Power cords used with AC-powered switches or AC power supplies must meet the
following requirements:
• The power cord must be agency-certied for the country of use.
• The power cord must have an IEC320-C13 connector for connection to the switch or
power supply.
• The power cord must have an appropriately rated and approved wall plug applicable
to the country of installation.
• For cords up to 6 feet (2 m) long, the wire size must be 18 AWG (.75 mm
2
) minimum;
over 6 feet, the minimum wire size is 16 AWG (1.0 mm
2
).
