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 and must not be used 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 from an AC source.
⚫To reduce the risk of fire or electrical shock, UPS installation must be in an environmentally
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.

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 to the load even when disconnected from the utility power.
Only after disconnecting the utility and DC power should authorized service personnel 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 type and number of sealed, lead-acid batteries.
⚫Do not open or mutilate the battery. Released 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.
CAUTION：
RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE. DISPOSE OF USED
BATTERIES ACCORDING TO THE INSTRUCTION.

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 is found, report it to the carrier immediately.
2. Verify the product label is correct.
3. If the equipment needs to be returned, carefully repack the equipment using the original
packing material.
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 (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 through ventilation
holes on the cabinet front door and exits through the cabinet top cooling fans. 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 below 40°C and humidity within 90%. If necessary,
install a system of room extractor fans to keep temperature below 40C.
6. Air filters are necessary if the UPS operates in a dusty environment.
7. If an external battery cabinet is used, it is recommended that the external battery cabinet is
located right next to the UPS cabinet. We recommend the following clearances:
⚫Keep a clearance of 100cm from the top of the UPS for maintenance, wiring and
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:
⚫Keep CO2 or dry powder fire extinguishers near the installation area.
⚫Install the UPS in an area where walls, floors and ceilings were constructed with 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 installation area. Refer to Figure 2-1. Please make sure
the bearing capacity of forklift is sufficient.
2. Please follow the orders in Figure 2-2 to remove carton and foams.

Figure 2-2

3. Put the ramp in the front of the cabinet. Refer to Figure 2-3.
Figure 2-3
4. Remove 2 fixing cabinet plates and loosen leveling feet by rotating them counterclockwise.
Then, move the cabinet from the pallet. Refer to Figure 2-4.
5. To fix the cabinet in position, simply rotate leveling feet clockwise. Refer to Figure 2-5.

Ramp

2.4 Moving the Cabinet
The UPS is fixed on the pallet with 2 fixing cabinet plates. When removing them, 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 an 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 third 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 bearing capacity of any handling equipment.
5. At the bottom of the UPS, the four casters help you move the UPS to a designated area. Before
you move the UPS, please turn the four leveling feet counterclockwise to raise them off the
ground. This protects the leveling feet from being damaged.
6. To fix the cabinet in position, simply rotate leveling feet clockwise.
7. One can re-use the 2 fixing cabinet plates to fix the cabinet firmly to the ground. Refer to Figure
2-6.
