Power cords used with AC-powered switches or AC power supplies must meet the following
requirements:
• The power cord must be agency-certified 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

The power cords for switches that use either the 1100 W or 715 W power supplies are keyed with a
“notch” to ensure the proper orientation when plugged in. These cords are of 3x14 AWG.
