2. Installation
2.1 Initial Inspection
1. Visually examine if there is any damage inside and outside of packages from 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.
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 top rear 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 below 40°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 36”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 the space 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.

2.4 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 four casters help you to 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 damage when moving the UPS.
