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 the Micro 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).

IMPORTANT SAFETY INSTRUCTIONS  
SAVE THESE INSTRUCTIONS.  
This manual contains important instructions that should be closely followed dur-  
ing installation and maintenance of this product.  
This product is designed for Commercial/Industrial use only. It is not intended  
for use with life support and other U. S. FDA designated “critical” devices. Max-  
imum load must not exceed that shown on the rating label. See Limited Warranty.  
WARNING:Lethal voltages may be present within this unit even when it is  
apparently not operating. Observe all cautions and warnings in this manual.  
Failure to do so MAY result in serious injury.  
This equipment or Micro SmartSwitch is designed for use on a properly  
grounded (earthed), 208/240 VAC, 50Hz or 60Hz supply.  
ELECTROMAGNETIC COMPATIBILITY- The Micro SmartSwitch complies  
with the limits for a CLASS B digital device, pursuant to part 15 of FCC rules.  
These limits provide reasonable protection against harmful interference. If this  
device is not installed and used in accordance with the instruction manual, it may  
cause harmful interference to radio communications. Not operating this device in  
accordance with these instructions may cause harmful interference, which the  
user must correct at their own expense.  
Operate the Micro SmartSwitch in an indoor environment only in an ambient  
temperature range of 0°C to 50°C (32°F to +122°F). Install it in a clean environ-  
ment, free from conductive contaminates, moisture, flammable liquids, gasses, or  
corrosive substances.  
Turn the Micro SmartSwitch off and isolate it from other equipment before  
cleaning. Use a soft cloth, never liquid or aerosol cleaners.  
Keep the vents free from dust accumulation that could restrict airflow.  
Never block or insert any object into the ventilation holes or other openings.

Installation  
Place rear rail [R] over the studs in the front rail [F]. Tighten nuts finger tight.  
The mounting tab [T] will be facing out, so the holes align with the rack sides.  
Adjust length of rail assembly to fit inside rack. Tighten either the wing nuts or  
hex nuts.  
Insert cage nut (one on each side) in rack. Set hooks at rear of rail over holes in  
rack. Use screw [2] (one on each side) to attach rails to rear of rack through cage  
nut. Use screw [2] (two on each side) to attach rails to front of rack.

Ground Bonding Screw  
A ground bond-  
ing screw is pro-  
vided on the rear  
of the unit. This  
feature is pro-  
vided as an  
attachment point  
for conductors  
the rack may  
contain for the  
purpose of func-  
tional grounding  
or bonding of  
ungrounded  
metal parts.  
Ground cables  
are not included.  
Note: The Ground Bonding wire must be a minimum of 10 AWG to maintain  
proper grounding.  
Connecting Devices  
Make sure that  
the devices con-  
nected do not  
exceed the unit  
capabilities.  
This Dual Input  
Micro Smart-  
Switch features  
3 output recepta-  
cles per circuit  
breaker, for a  
total of 12  
receptacles.  
This model is  
rated at 10A per  
breaker.  
Each block of 3  
receptacles has a maximum output rating of 10A. If the total connected load  
exceeds 10A, the circuit breaker will trip and interrupt power to all loads attached  
to that block of receptacles.  
The maximum output of this Micro SmartSwitch is 24A. If the total load con-  
nected to all load segments exceed 24A, the circuit breaker at the wall could trip  
and interrupt power to all loads.

About the Circuit Breakers  
Input power can be verified by the illumination of the two LEDs on the front of  
the unit, marked ~A and ~B.  
Output power can be verified by the illumination of the circuit breaker, when in  
the On position  
If connected device is not powered, verify the respective circuit breaker is On  
and illuminated.  
If power is still not restored, see “Contacts” section later in this document.

Configurations  
The Micro SmartSwitch can be configured to fit several power distribution  
requirements.  
Configuration 1  
This application shows use of the Micro SmartSwitch in conjunction with single-  
line cord devices .  
Note: Each segment can accommodate a maximum current draw of 10A, so the  
individual load connected to it must not exceed 10A or the circuit breaker will  
trip.

accommodate a maximum cur-  
rent draw of 10A, so the individ-  
ual load connected to it must not  
exceed 10A or the circuit  
breaker will trip.
