1. Important Safety Warnings
Strictly comply with all warnings and operating instructions in this manual. Save this manual and carefully
read 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
Transport the UPS system only in the original packaging to protect against shock and impact.
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 a heater.
• Do not block ventilation holes in the UPS housing.
1.3 Installation
• Do not connect devices which may overload the UPS system (e.g. laser printers) to the UPS output
sockets.
• Ensure cables do not present a trip hazard.
• Do not connect domestic appliances (such as hair dryers) to UPS output sockets.
• The UPS may be operated by individuals with no previous experience.
• The UPS may be operated in TN & TT power distribution.
• Connect the UPS system only to an earthed shockproof outlet, easily accessible and close to the
UPS system.
• Use only UL-tested, UL-marked power cables to connect load(s) to the UPS system.
• Ensure that the sum of the leakage current of the UPS and the connected devices does not exceed
3.5mA.
• Units are considered acceptable for use in a maximum ambient of 104°F (40°C). See 5.1 Operation
for more detail.
• CAUTION: The unit is heavy; lifting it requires a minimum of two people.
1.4 Operation
• Do not disconnect the mains cable on the UPS system or the building wiring outlet (shockproof
socket outlet) during operation. This negates the protective earth of the UPS system and all
connected loads.
• The UPS system features its own internal power source (batteries). The UPS output sockets may
be electrically live even if the UPS system is not connected to the building outlet.
• In order to fully disconnect the UPS system, first press the OFF/Enter button and disconnect from
mains.
• Prevent fluids or other foreign objects from getting inside the UPS system.
• The EPO, RS-232 and USB circuits are IEC 60950 safety extra low voltage (SELV) circuits. This
circuit must remain separated from any hazardous voltage circuits by reinforced insulation.

• The UPS system operates with hazardous voltages. Repairs should be carried out only by qualified
maintenance personnel.
DANGER - 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 no
hazardous voltage exists in the terminals of capacitors such as BUS-capacitors.
• To avoid electrical shock, turn off the unit and unplug it from the AC power source before servicing
the battery.
• Only persons adequately familiar with batteries and required precautionary measures should
replace batteries and supervise operations.
DANGER - Risk of electric shock. The battery circuit is not isolated from the input voltage.
Hazardous voltages may occur between battery terminals and ground. Before touching, verify
that no voltage is present.
• Do not dispose of batteries in a fire.
• Do not open or destroy batteries. Escaping electrolyte may be toxic and cause injury to skin and
eyes.
• When replacing batteries, replace with the same number and type of batteries.
Toplite (Guangzhou) Technology

CSB Battery Co Ltd (MH14533)
DANGER – Batteries present a risk of electrical shock and high short-circuit current. The following
precautions should be observed when working on batteries:
a. Remove watches, rings, or other metal objects.
b. Use tools with insulated handles.
c. Wear rubber gloves
and boots.
d. Do not lay tools or metal parts on top of batteries.
e. Disconnect charging source prior to connecting or disconnecting battery terminals.
f. Verify battery is not inadvertently grounded. If inadvertently grounded, remove source
from ground. Contact with any part of a grounded battery can result in electrical shock.
The likelihood of such shock are reduced when such grounds are removed during
installation and maintenance.

Plug the UPS into a two-pole, three-wire, grounded receptacle only. Avoid using extension cords.
Note: If the UPS is connected to an improperly wired outlet, the site wiring fault indicator will
show on the LCD. (Refer to 4. Troubleshooting).
WARNING: For 1 kVA and 1.5 kVA models, to reduce the risk of fire, connect only to a circuit
provided with 15 amperes maximum branch circuit overcurrent protection in accordance with the
National Electric Code, ANSI/NFPA 70.
WARNING: For 2 k VA models, to reduce the risk of fire, connect only to a circuit provided with 20
amperes maximum branch circuit overcurrent protection in accordance with the National Electric
Code, ANSI/NFPA 70.
WARNING: For 3 k VA models, to reduce the risk of fire, connect only to a circuit provided with
30 amperes maximum branch circuit overcurrent protection in accordance with the National
Step 2: UPS output connection
There are two outlet banks: programmable outlets and general outlets. Connect non-critical devices to
the programmable outlets and critical devices to the general outlets. During power failure, the backup
time may be extended to critical devices by providing shorter backup time for non-critical devices.
Step 3: Network connection
RJ45 surge port
Electric Code, ANSI/NFPA 70.
Connect a single modem/phone/fax line into surge-protected “IN” outlet on the back panel of the UPS
unit. Connect from “OUT” to the equipment with another modem/fax/phone line cable.
Step 4: Disable / Enable EPO function
Keep pin 1 and pin 2 closed for UPS normal operation. To activate EPO function, open contact between
pin 1 and pin 2.

When input voltage is beyond the acceptable range or
power failure occurs, alarm will sound every 5 seconds
and UPS is transferred to battery
When input voltage is within acceptable range but UPS
is in overload, UPS will enter bypass mode. Alarm
sounds every 10 seconds.

5.1 Operation
The UPS system contains no user-serviceable parts. If the battery service life (3-5 years at 77°F (25°C)
ambient temperature) has been exceeded, the batteries must be replaced. Contact Staco Energy
Products for replacement battery packs.
5.2 Storage
Before storing, charge the UPS for 5 hours. Store the UPS covered and upright in a cool, dry location.
During storage, recharge the battery in accordance with the following table:
5.3 Recommended Replacement Intervals
Do not discard the UPS or UPS batteries in landfill. The batteries in the UPS are
sealed lead acid and recyclable. Refer to local codes; for proper disposal contact
your local recycling/reuse or hazardous waste center.
The Staco UPS has a long design life. Due to the characteristics of the part, not the design of the UPS,
certain components used in the design have a limited life, even with proper maintenance.
Service and maintenance work should be performed only by factory authorized service
personnel.
Staco recommends these limited-life components be periodically inspected and replaced before the
expected expiration of their life cycle. The recommended replacement schedule is an estimate only. The
life of these parts depends on site conditions such as ambient temperature, load profile, cleanliness of
environment and other factors.
Staco Recommends a Factory Authorized Preventative Maintenance review is schedule at least once a
year.
The functional lifetime of VRLA batteries is significantly affected by the temperature at which they are
stored and operated. Ideally, VRLA batteries should be used in a 25ºC (77ºF) environment. For every
8.3ºC (15ºF) increase in temperature, the life expectancy of a battery will be halved. Exposure to
temperatures in excess of 32ºC (90ºF) should be limited to no more than 30 days per year. Under no
circumstances should the VRLA battery be exposed to temperatures over 40ºC (104ºF) which can lead to
thermal runaway, a condition that damages the battery. Thermal runaway can cause batteries to swell.
If the battery cases burst, the hazardous contents may be exposed.
Maintaining appropriate ambient temperature typically requires installing the UPS in a temperature
controlled space. Areas without AC do not generally maintain the proper conditions for good battery life.
