Safety Instructions
Safety Instructions
As dangerous voltages are present within the UPS, only an Emerson technician or an Emerson-authorized
technician is permitted to open it. Failure to observe this could result in electric shock risk and invalidatio n
of any implied warranty
Transport
• Please transport the UPS system only in the original packaging (to protect against shock and
impact).
Set-up
•
Condensation may occur if the UPS system is moved directly from a cold to a warm environ ment.
The UPS system must be absolutely dry before being installed. Please allow an acclimatization
time of at least two hours.
•
Do not install the UPS system near water or in damp environments.
•
Do not install the UPS system where it would be exposed to direct sunlight or n ear heat source.
•
Do not block off ventilation openings in the UPS system’s hou sin g.
Installation
This manual contains information concerning the installation and operation of the Emerson Network Power
Liebert PSA itON Uninterruptible Power System (UPS)
All relevant parts of the manual should be read prior to commencing the installation.
• Do not connect appliances or equipment (e.g. laser printer) to the output socket, which would
overload the UPS system.
• Place cables in such a way that no one can step on or trip over them.
• Do not connect domestic appliances such as hair dryers to UPS output sockets.
• Connect the UPS system only to an earthed shockproof socket outlet. Connection to any type of
receptacle other than two pole, three wire grounded receptacle may result in shock hazard
• The building wiring socket outlet (shockproof socket outlet) must be easily accessible and close
to the UPS system.
• Please use only VDE-tested, CE-marked mains cable (e.g. the mains cable of your computer) to
connect the UPS system to the building wiring socket outlet (shockproof socket outlet).
• Please use only VDE-tested, CE-marked power cables to connect the loads to the UPS system.
• The UPS must be serviced by an authorized representative of Emerson Network Power. Failure
to do so could result in personnel safety risk, equipment malfunction and invalidation of warranty.
• The Liebert PSA itON has been designed for Commercial/Industrial use only, and is not
recommended for use in life support applications.
• In the event of Emergency press 'OFF' button and disconnect the power cord from AC Power
supply to properly disable the UPS
• Do not plug UPS input to its own output. Do not attach power-strip or surge suppressor to the UPS

Operation
• Do not disconnect the mains cable on the UPS system or the building wiring socket outlet
(shockproof socket outlet) during operations since this would cancel the protectiv e ea rthing of the
UPS system and of all connected loads.
• The UPS system features its own, internal current source (batteries). The UPS output sockets or
output terminals block may be electrically lived even if the UPS system is not connected to the
building wiring socket outlet.
• In order to fully disconnect the UPS system, first press the Standby switch then disconnect the
mains lead.
• Ensure that no fluids or other foreign objects can enter the UPS system.
Maintenance, servicing and faults
• The UPS system operates with hazardous voltages. Repairs may be carried out only by qualified
maintenance personnel.
• Caution - risk of electric shock. Even after the unit is disconnected from the mains power supply
(building wiring socket outlet), components inside the UPS system are still connected to the
battery and are still electrically live and dangerous.
• Before carrying out any kind of servicing and/or maintenance, disconnect the batteries and verify
that no current is present and no hazardous voltage exist in the terminals of high capability
capacitor such as BUS-ca pacitors.
• Only persons who are familiar with batteries and with the required precautionary measures may
replace batteries and supervise operations. Unauthorised persons must be kept well away from
the batteries.
• Caution - risk of electric shock. The battery circuit is not isolated from the input voltage.
Hazardous voltages may occur between the battery terminals and the ground. Before touching,
please verify that no voltage is present!
• Batteries may cause electric shock and have a high short-circuit current. Please take the
precautionary measures specified below and any other measures necessary when working with
batteries:
- remove wristwatches, rings and other metal objects
- use only tools with insulated grips and handles
• Do not short circuit battery terminals
• When changing batteries, install the same number and same type of batteries.
• Do not attempt to dispose of batteries by burning them. This could cause battery explosion.
• Do not open or destroy batteries. Escaping electrolyte can cause injury to the skin and eyes. It
may be toxic.
• Please replace the fuse only by a fuse of the same type and of the same amperage in order to
avoid fire hazards.
• Do not dismantle the UPS system
