About This Device

This guide serves as an outline to assist Qualified personnel with the installation
of the Liebert Micro SmartSwitch. The input voltage for this Micro SmartSwitch
unit is 200VAC to 240VAC.
This Micro SmartSwitch includes the following features:
• Mounts in 1U of rack space
• Provides 12 receptacles on 4 circuit breakers
• Protects against electrical line surges and spikes
This Micro SmartSwitch is UL and c-UL listed as Information Technology
Equipment.
WARNING: There is a risk of personal injury from electrical shock
and hazardous energy levels. The installation of options and routine
maintenance and service of the product must be performed by individuals
who are knowledgeable about the procedures, precautions, and hazards
associated with AC power products (trained service technician).
To reduce the risk of electrical shock and/or equipment damage when installing
or servicing the Micro SmartSwitch:
• The Micro SmartSwitch must be disconnected from the product and
unplugged from the AC electrical outlet before servicing or repairing prod-
uct.
• Do not overload the output of the Micro SmartSwitch. The total connected
load should not exceed rated input power.
• Do not exceed the leakage current limit for theMicro SmartSwitch in your
system. See the “Earth Leakage Current” section later in this document for
limits.
Earth Leakage Current
To reduce the risk of electrical shock due to high leakage current, a reliable
grounded (earth) connection is essential before connecting Micro SmartSwitch to
AC power. Observe the following limits when connecting the product to AC
power distribution devices.
For products that have attached AC power cords directly connected to the build-
ing power, the total combined leakage current should not exceed 5 percent of the
rated input current for the device.
For products that have detachable AC power cords, the total combined leakage
current should not exceed 3.5mA.
Voltage Selection
On connected equipment that have voltage select switches, make sure that the
switch is set for the type of voltage you use (208/240 VAC).
