AC Power Cable Requirements
Use an AC power cable appropriate for your country. Check your local electrical codes and regulatory
agencies for power cable requirements. The countries listed in Table 13 have additional requirements as
listed in the table.
NOTE
When using dual power supplies, make sure that each AC power supply attaches to an independent power source.
Replacing the Power Cable
If the power cable plug is unsuitable and must be replaced, connect the power supply wires for the
switch according to the following scheme:
● Brown wire to the Live (Line) plug terminal, which may be marked with the letter “L” or colored
red.
● Blue wire to the Neutral plug terminal, which may be marked with the letter “N” or colored black.
● Yellow/Green wire to the Ground plug terminal, which may be marked with the letter “E” (the
Earth symbol) or colored yellow/green.
Uninterruptible Power Supply Requirements
An uninterruptible power supply (UPS) is a device that sits between a power supply (such as a wall
outlet) and a device (such as a switch) to prevent outages, sags, surges, and bad harmonics from
adversely affecting the performance of the device.
A UPS traditionally can perform the following functions:
● Absorb relatively small power surges.
● Smooth out noisy power sources.
● Continue to provide power to equipment during line sags.
● Provide power for some time after a blackout has occurred.
In addition, some UPS or UPS plus software combinations provide the following functions:
● Automatically shut down equipment during long power outages.
