● If your switch includes more than one power supply, connect each power supply to a different,
independent power source.
If a power source fails, it will affect only the switch power supply to which it is connected. If all
switch power supplies are connected to a single power source, the entire switch is vulnerable to a
power source failure.
● In regions that are susceptible to electrical storms, we recommend that you plug your system into a
surge suppressor.

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 a Power Cable
If a 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.
