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 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.
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 Back feed
The isolation device must be able to carry the UPS input current.
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.

1.4 Maintenance
•Only qualified service personnel should perform the battery installation.
•The following PRECAUTIONS should be observed:
1. Remove watches, rings, or other metal objects. Use tools with insulated handles.
2. Wear rubber gloves and boots.
3. Do not lay tools or metal parts on top of batteries or battery cabinet
4. Disconnect the charging source prior to connecting or disconnecting terminal.
5. 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 util-
ity and DC power, authorized service personnel should attempt internal access to the UPS.
•Do not disconnect the batteries while the UPS is in Batterymode.
•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
•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 exhaustedthrough 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 5,200 ft 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 40” from the top of the UPS for maintenance, wiring and ventilation.
•Keep a clearance of 36" back clearance, or install flex-conduit to allow for moving of cabinet to access
switches. When pushed toward wall, leave 6" of clearance for ventilation.
•Front clearance should be per local and NEC code.
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 of fireproof materials.
9. Do not allow unauthorized personnel to enter the installation area. Assign specific personnel to keep the
UPS key.
