Chapter 1 Installation

1.3 Positioning

1.3.1 Distribution Room

The UPS is designed for indoor installation, which shall be located in a clean environment with

adequate ventilation to keep the environmental temperature within the required specification. The UPS

uses forced convection cooling by internal fans. Cooling air enters the module through ventilation grills

located at the front part of the cabinet and exhausted through grills located in the rear part of the cabinet.

Please do not block the ventilation holes.

If necessary, a system of extractor fans should be installed to aid cooling-air flow. An air filter should

be used when the UPS is to operate in a dirty environment and should be regularly cleaned to maintain

airflow.

Note: The UPS should be installed on a cement surface or other surface that is not

combustible.

1.3.2 Battery Room

The battery will generate some amount of hydrogen and oxygen at the end of charging, so the

fresh air volume of the battery installation environment must meet EN50272-2001 requirements. The

ambient temperature of the battery must be stable. Ambient temperature is a major factor in determining

the battery capacity and life. The nominal operating temperature of battery is 20°C. Operating above this

temperature will reduce the battery life, and operation below this temperature will reduce the battery

capacity. If the average operating temperature of battery is increased from 20ºC to 30ºC, then the

service life of the battery will be reduced by 50%. If the operating temperature of the battery is above

40ºC, then the battery service life will be decreased in exponent rate. In a normal installation, the battery

temperature is maintained between 15°C and 25°C. Keep batteries away from heat sources or air

outlets.

If external batteries are to be used, a battery protection device (a DC circuit breaker) must be

mounted as close as possible to the batteries, and the connecting cables should be as short as possible.

1.3.3 Storing

If the equipment is not installed immediately, it must be stored in a room so as to protect it against

excessive humidity and heat sources. The battery needs to be stored in dry and cool place with good

ventilation. The most suitable storage temperature is 20 ºC to 25ºC.

1.4 Disassembly, Initial Checking and Positioning

Check the packaging first upon the arrival of product to see if there is any damage; open the

packaging to check the equipment; report any such damage to the shipper immediately.

1.4.1 System Packaging:

Open the wooden case first, the open method is shown in fig 1-1:
