4.2.1 AC Power Supply and Power Cords
I. AC power
Caution:
If an outdoor AC power cord should be directly led to the switch, please serially connect the lightning
arrester for AC Power (Socket Strip with Lightning Protection) before you plug AC power cord into the
switch, thus to prevent the possible damage to the switch due to lightning strike. Refer to the section
“Installation of Power Lightning Arrester” in the appendix.
Rated voltage: 100-240V a.c.; 50/60Hz
Maximum voltage:90-264V a.c.; 50/60Hz

Note:
S3526 Ethernet Switch with AC power input has no power switch on its panel.
II. Recommended AC power socket
A monophase 3-wire power socket with a neutral point connector, or a multi-functional
power socket for the computer is recommended. The neutral point of the power in a
building must be reliably grounded. Normally, the neutral point of the power supply
system in a building is buried in the ground during the construction and wiring. The user
must make sure that the power supply for the building is grounded.
