1. Important Safety Warning
Please comply with all warnings and operating instructions in this manual. Save this manual
properly and read carefully the following instructions before installing the unit. Do not operate
this unit before reading through all safety information and operating instructions carefully
1-1. Transportation
Please transport the UPS system only in the original package to protect against shock
and impact.
Handling Safety
Do not lift heavy loads without assistance.
This equipment is intended for installation in a controlled temperature indoor area free
from conductive contaminants.
1-2. Preparation
Condensation may occur if the UPS system is moved directly from cold to warm
environment. The UPS system must be absolutely dry before being installed. Please
allow at least two hours for the UPS system to acclimate to the environment.
Do not install the UPS system near water or in moist environments.
Do not install the UPS system where it would be exposed to direct sunlight or near
heater.
Do not block ventilation holes in the UPS housing.
1-3. Installation
Do not connect appliances or devices which would overload the UPS system (e.g. laser
printers) to the UPS output sockets.
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.
The UPS can be operated by any individuals with no previous experience.
Connect the UPS system only to an earthed shockproof outlet which 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 outlet (shockproof outlet).
Please use only VDE-tested, CE-marked power cables to connect the loads to the UPS
system.
Pluggable equipment includes a protective earth conductor that carries the leakage
current from the load devices ( computer equipment ). Total leakage current must not
exceed 3.5mA.

www.powershield.com.au 5
1-4. Operation
Do not disconnect the mains cable on the UPS system or the building wiring outlet
(shockproof socket outlet) during operations since this would cancel the protective
earthing 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 live even if the UPS system is not
connected to the building wiring outlet.
In order to fully disconnect the UPS system, first press the OFF/Enter button to
disconnect the mains.
Prevent no fluids or other foreign objects from inside of the UPS system.
1-5. Maintenance, service 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
(building wiring outlet), components inside the UPS system are still connected to the
battery and electrically live and dangerous.
Before carrying out any kind of service and/or maintenance, disconnect the batteries
and verify that no current is present and no hazardous voltage exists in the terminals of
high capability capacitor such as BUS-capacitors.
Only persons are adequately familiar with batteries and with the required precautionary
measures may replace batteries and supervise operations. Unauthorized 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.
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 is toxic.
Please replace the fuse only with the same type and amperage in order to avoid fire
hazards.
Do not dismantle the UPS system.

Tower Installation
Step 1
Step 2
Step 3
2-3. Setup the UPS
Step 1: UPS input connection
Plug the UPS into a two-pole, three-wire, grounded receptacle only. Avoid using extension cords.
Step 2: UPS output connection
There two kinds of outputs: programmable outlets( white coloured outlets )and general
outlets ( black coloured outlets ).
Please connect non-critical devices to the programmable outlets and critical devices to
the general outlets.
During power failure, you may extend the backup time to critical devices by setting shorter
backup time for non-critical devices.

www.powershield.com.au 8
Step 3: Communication connection
Interface ports:
USB port RS-232 port Intelligent slot
To allow for unattended UPS shutdown/start-up and status monitoring, connect the
communication cable one end to the USB/RS-232 port and the other to the communication port
of your PC. With the monitoring software installed, you can schedule UPS shutdown/start-up and
monitor UPS status through PC.
The Commander RT series are equipped with intelligent slot perfect for either SNMP or AS400
card. When installing either SNMP or AS400 card in the UPS, it will provide advanced
communication and monitoring options.
NOTE : USB port and RS-232 port cannot work at the same time.
Step 5: EPO ( Emergency Power OFF ) function
Keep the pin 1 and pin 2 closed for UPS normal operation. To activate EPO function, cut the wire
between pin 1 and pin 2.
Step 6: External battery connection (for Commander RT 2000 and 3000)
Connect one end of external battery cable to UPS unit and the other end to battery box. Use
supplied battery detection wire in detection port of UPS unit and plug the other end to battery
bank. See below chart for detailed connection.
Models : PSCRT2000,PSCRT3000
PSRTBB8(2K only)/PSRTBB12(3K only)
NOTE: Maximum connected external battery boxes up to 2 units.
It’s in closed status for UPS
normal operation.

www.powershield.com.au 9
Step 7: Turn on the UPS
Press the ON/Mute button on the front panel for two seconds to power on the UPS.

Operating mode
Description
LCD display
ECO mode
When the input voltage is within voltage
regulated range, UPS will power the output
directly from the mains. ECO is an
abbreviation of Efficiency Corrective
Optimizer mode.
In this mode, when battery is fully
charged, the fan will stop working for
energy saving.
Buck mode
when AC is
normal.
When the input voltage is higher than the
voltage regulation range but lower than
high loss point, the buck AVR will be
activated.
Boost mode
when AC is
normal.
When the input voltage is lower than the
voltage regulation range but higher than
low loss point, the boost AVR will be
activated.
Battery mode
When the input voltage is beyond the
acceptable range or power failure and
alarm is sounding 2 beeps every 30
seconds, UPS will backup power from
battery.
Standby mode
UPS is powered off and no output supply
power, but still can charge batteries.
