1. Safety
1.1 Important Safety Instructions
This UPS contains LETHAL VOLTAGES. All repairs and service must be performed by AUTHORIZED
SERVICE PERSONNEL ONLY. There are NO USER SERVICEABLE PARTS inside the UPS.
WARNING:
The UPS is designed for commercial and industrial purpose. It is forbidden to apply for any life
sustainment and support.
The UPS system contains its own energy source. The output terminals may carry live voltage
even when UPS is disconnected to an AC source.
To reduce the risk of fire or electrical shock, UPS installation has to be in a controlled room
where temperature and humidity are monitored. Ambient temperature must not exceed 40°C.
The system is only for indoor use.
Ensure all power is disconnected before installation or service.
Service and maintenance should be performed by qualified personnel only.
1.2 EMC
WARNING:
This is a product for commercial and industrial application in the second environment - installation
restrictions or additional measures may be needed to prevent disturbances.
1.3 Installation information
WARNING:
Installation must be performed by qualified personnel only.
The cabinets must be installed on a level floor suitable for computer or electronic equipment.
The UPS cabinet is heavy. If unloading instructions are not closely followed, cabinet may
cause serious injury.
Do not tilt the cabinets more than 10 degree.
Before applying electrical power to the UPS, make sure the Ground conductor is properly
installed.
Installation and Wiring must be performed in accordance with the local electrical laws and
regulations.
The disconnection device should be chosen based on the input current and should break line
and neutral conductors - four poles for three phases.
Before working on this circuit
- Isolate Uninterruptible Power System (UPS)
- Then check for Hazardous Voltage between all terminals
including the protective earth.
Risk of Voltage Backfeed
The isolation device must be able to carry the UPS input current.

1.4 Maintenance
WARNING:
Only qualified service personnel should perform the battery installation.
The following PRECAUTIONS should be observed
(1.) Remove watches, rings, or other metal objects.
(2.) Use tools with insulated handles.
(3.) Wear rubber gloves and boots.
(4.) Do not lay tools or metal parts on top of batteries or battery cabinets.
(5.) Disconnect the charging source prior to connecting or disconnecting terminal.
(6.) Check if the battery is inadvertently grounded. If it is, remove the source of grounding.
Contacting with any part of the ground might result in electrical shock. The likelihood of
such shock can be prevented if such grounds are removed during installation and
maintenance.
UPS is designed to supply power even when disconnected from the utility power. After
disconnect the utility and DC power, authorized service personnel should attempt internal
access to the UPS.
Do not disconnect the batteries while the UPS is in Battery mode.
Disconnect the charging source prior to connecting or disconnecting terminals.
Batteries can result in a risk of electrical shock or burn from high short circuit current.
When replacing batteries, use the same number of sealed, lead-acid batteries.
Do not open or mutilate the battery. Release electrolyte is harmful to the skin and eyes, and
may be toxic.
1.5 Recycling the used battery
WARNING:
Do not dispose of the battery in a fire. Battery may explode. Proper disposal of battery is
required. Refer to your local codes for disposal requirements.
Do not open or mutilate the battery. Released electrolyte is harmful to the skin and eyes. It
may be toxic.
Do not discard the UPS or the UPS batteries in the trash. This product contains sealed,
lead-acid batteries and must be disposed properly. For more information, contact your local
recycling/reuse or hazardous waste center.
Do not discard waste electrical or electronic equipment (WEEE) in the trash. For proper
disposal, contact your local recycling/reuse or hazardous waste center.

2. Installation
2.1 Initial Inspection
1. Visually examine if there is any damage inside and outside of packages in the process of the
transportation. If any damage, report it to the carrier immediately.
2. Verify the product label and confirm the consistency of the equipment.
3. If the equipment needs to be returned, carefully repack the equipment by using the original
packing material that came with.
2.2 Installation Environment
1. The UPS is designed for indoor use only and should be located in a clean environment with
adequate ventilation to keep the environmental parameters within the required specification.
2. Make sure that transportation routes (e.g. corridor, door gate, elevator, etc.) and installation
area can accommodate and bear the weight of the UPS, the external battery cabinet and
handling equipment.
3. The UPS uses forced convection cooling by internal fans. Cooling air enters the module
through ventilation grills located at the front of the cabinet and exhausted through grills
located in the rear part of the cabinet. Please do not block the ventilation holes.
4. Ensure that the installation area is spacious for maintenance and ventilation.
5. Keep the temperature of installation area around 30°C and humidity within 90%. The highest
operating altitude is 1000 meters above sea level.
6. If necessary, install a system of room extractor fans to avoid formation of room temperature.
Air filters are necessary if the UPS is operated in a dusty environment.
7. It is recommended that you parallel the external battery cabinets to the UPS. The following
instructions of clearances are suggested:
 Keep a clearance of 100cm from the top of the UPS for maintenance, wiring and
ventilation.
 Keep a clearance of 100cm from the back of the UPS and the external battery cabinets for
ventilation.
 Keep a clearance of 150cm from the front of the UPS and the external battery cabinets
for maintenance and ventilation.
8. For safety concerns, we suggest that you shall:
 Equip with CO2 or dry powder fire extinguishers near the installation area.
 Install the UPS in an area where the walls, floors and ceilings were constructed by
fireproof materials.
9. Do not allow unauthorized personnel to enter the installation area. Assign specific personnel
to keep the UPS key.

2.3 Unpacking
1. Use a forklift to move the product to installed area. Refer to Figure 2-1. Please make sure the
bearing capacity of forklift is sufficient.
2. Please follow the order in Figure 2-2 to remove carton and foams.

2.4 Moving the Cabinet
The UPS is fixed on the pallet with 2 fixing cabinet plates. When removing it, pay attention to
the movement of the casters to avoid accidents.
The cabinet can be pushed forward or backward only. Pushing it sideward is not allowed.
When pushing the cabinet, pay attention not to overturn it as the gravity center is high.
1. If you need to move the UPS over a long distance, please use appropriate equipment like a
forklift. Do not use the UPS casters to move over a long distance.
2. After the UPS has been removed from the pallet to ground, we suggest that at least three
people move the UPS to the installation area. One person holds a lateral side of the UPS with
hands, another holds the other lateral side of the UPS with hands, and the other person pushes
the UPS either from the front side or from the back side to the installation area and avoid
tipping the UPS.
3. The casters are designed to move on level ground. Do not move the UPS on an uneven surface.
This might cause damage to the casters. Toppling the UPS could also damage the unit.
4. Ensure that the weight of UPS is within the designated bearing capacity of any handling
equipment.
5. At the bottom of the UPS, the two casters help you to move the UPS to a designated area.
Before you move the UPS, please turn the two leveling feet counterclockwise to raise them off
the ground. This protects the leveling feet from damage when moving the UPS. Refer to Figure
2-5.
