Initial Inspection
Before installing the UPS, carry out the following inspections:
1. Ensure that the UPS equipment room meets the environmental requirements specified in the product technical
specifications, especially the ambient temperature, ventilation conditions, and the levels of dust.
2. Unpack the UPS and battery under the supervision of an authorized service engineer. Visually inspect the inside
and outside of the UPS and battery for any shipping damage. If there is any damage, report it to the carrier
immediately.
3. Verify the UPS label and confirm that the UPS model conforms to the information indicated on it. The UPS label is
attached to the rear of the door. The UPS model, capacity and the main parameters are marked on the label.

Environmental Requirements
Selecting the UPS Location
The UPS should be located in a cool, dry, clean-air indoor environment with adequate ventilation, and should be
located on concrete or other non-flammable, flat surfaces. The surrounding environment should be free from
conductive powders (such as metallic powder, sulphide, sulphur dioxide, graphite, carbon fibre, conductive fibre,
etc.), acid mist or other conductive media (strongly ionized substances). The environmental specifications should
comply with relevant international standard & specifications and the operating range (see Table 10-2) specified in
this manual.
The UPS uses forced cooling by internal fans. Cooling air enters the UPS through the ventilation grills at the front of
the cabinet and is expelled through the ventilation grills at the back of the cabinet. Do not obstruct the ventilation
holes (ventilation grills). The rear of the UPS should be kept a distance at least 200mm from the wall to avoid
blocking the UPS heat dissipation, thus reducing the UPS internal temperature and improving the UPS life.
If necessary, install indoor extractor fans to aid cooling-air flow and avoid temperature build-up in the installation
area.
Note
Note 1: When the battery cabinet is installed near the UPS, the maximum allowable ambient temperature is dependent on
the battery rather than the UPS.
Note 2: If the UPS is operating in ECO mode, the power consumption will be less than in Normal mode. A proper air
conditioning system shall be selected according to the normal operating mode.
Selection the Battery Location
Batteries generate a certain amount of hydrogen and oxygen at the end of the charging cycle, so the fresh air
volume of the battery installation environment must meet the EN50272-2001 requirements.
The ambient temperature is the main factor that affects the battery capacity and life. The normal operating
temperature of the battery is 20°C. If the ambient temperature is higher than 20°C, the battery life will be reduced. If
it is lower than 20°C, the battery capacity will be reduced. Under normal operating conditions, the acceptable
ambient temperature for the battery is 15°C to 25°C. The ambient temperature of the battery must be maintained
constant, and the battery must be kept away from heat sources and air outlets.
The battery may be installed inside the dedicated battery cabinet, which shall be positioned close to the UPS. If the
battery is placed on the raised floor, brackets shall be installed under the floor, just as for the UPS. In the case of
rack-mounted batteries or batteries that are installed remotely from the UPS, the battery circuit breaker shall be
installed close to the battery, and the cable lengths shall be kept to a minimum.
Storage
Should the UPS not be installed immediately, it must be stored in its original packaging in a location where it is
protected against excessive humidity and heat sources (see Table 10-2). The battery must be stored in a dry and
cool place with good ventilation. The most suitable storage temperature is between 20°C and 25°C.
