3.4.1 Before Installation
Due to different installation environments, please read this user manual thoroughly before
installation and wiring. Only authorized engineers or service personnel can perform installation and
maintenance. If you want to install the UPS by yourself, installation must be under the supervision
of authorized engineers or service personnel.
If you use a forklift or other equipment to move the UPS, please make sure its load bearing is
sufficient.
3.4.2 Installation Environment
The UPS is designed for indoor use only. Do not install or place it in an outdoor area.
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.
Ensure that the installation area is big enough for maintenance and ventilation.
Keep the installation area’s temperature around 30°C and humidity within 90%. The highest
operating altitude is 2000 meters above sea level.
The UPS is intended for indoor installation and should be located in an environment with clean
air and with adequate ventilation to keep the ambient temperature within the specified
operating range. The UPS is air-cooled with the aid of internal fans. Cold air enters the UPS
through.
If necessary, install a system of room extractor fans to avoid room temperature build-up. Air
filters are necessary if the UPS is operated in a dusty environment.
Note: The UPS is suitable for mounting on concrete or other non-combustible surface only.
The UPS is air-cooled with the aid of internal fans. Cold air enters the UPS through the
ventilation grilles at the front of the cabinet and hot air is released through the grilles at the
back. Do not cover the ventilation openings.
Do not allow unauthorized personnel to enter the installation area. Assign specific personnel to
keep the UPS key.

13
For safety concerns, we suggest that you shall:
1. Surroundings of the installation area with CO2 or dry powder fire extinguishers.
2. Install the UPS in an area where the walls, floors and ceilings were constructed by fireproof
materials.
It is recommended that you parallel the external battery cabinets to the UPS. The following
clearances are suggested:
1. Keep a clearance of 100cm from the top of the UPS for maintenance, wiring and ventilation.
2. Keep a clearance of 100cm from the back of the UPS and the external battery cabinets for
ventilation.
3. Keep a clearance of a 150cm from the front of the UPS and the external battery cabinets for
maintenance and ventilation.
3.4.3 Transportation
Warning
The UPS is fixed on the pallet with four balance supports. 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, take care
not to overturn it as the gravity center is high.
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 the over a long distance.
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 use hands to hold a lateral side of
the UPS, one person hold the other lateral side of the UPS with hands, and one person use
hands to push the UPS either from the front side or from the backside to move the unit to the
installation area and avoid tipping the UPS.
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 or tip the UPS which could damage the unit.
Ensure that the UPS weight is within the designated surface weight loading of any handling
equipment.
At the bottom of the UPS, there are four casters to 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.
Please use sufficient manpower(at least six people) and equipment (e.g. forklift) to carefully
move the UPS from its pallet to ground. Please pay attention to the movement of the casters to
avoid accidents.
