Chapter 2 Installation Guidance
2.1 Introduction
This
chapter introduces UPS installation, it provide normal installation steps and ideas. Please installation engineers
operate according to each place difference,
Warning-Installation can only be done by authorized engineers
1. Do not apply electrical power to the UPS equipment before the approval of commissioning
engineer.
2. The UPS should be installed by a qualified engineer in accordance with the information contained
in this chapter.
Note: 3-Phase 4-Wire Input Power is required
The standard UPS can be connected to TN, TT AC distribution system (IEC60364-3) of 3-phase
5-wire.For IT system please contact us.
WARNING: battery hazards
SPECIAL CARE SHOULD BE TAKEN WHEN WORKING WITH THE BATTERIES ASSOCIATED
WITH THIS EQUIPMENT. When connecting the battery, the battery terminal voltage will exceed
400Vdc and is potentially lethal.
l
Eye protection should be worn to prevent injury from accidental electrical arcs.
l
Remove rings, watches and all metal objects.
l
Only use tools with insulated handles.
l
Wear rubber gloves.
l
If a battery leaks electrolyte, or is otherwise physically damaged, it must be replaced, stored in a
container resistant to sulfuric acid and disposed of in accordance with local regulations.
l
If electrolyte comes into contact with the skin, the affected area should be washed immediately
with water.
2.2.1 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 or in front and botton
(NS3030) 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.

2.2.2 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 20
º
C to
30
º
C, then the service life of the battery will be reduced by 50%. If the operating temperature of the battery is above 40
º
C,
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.
2.2.3 Storing
If the equipment not be 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
º
C to 25
º
C.
2.3 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.
2.3.1 System Packing
Remove the carton box and the plastic film first, thensee.Durig the procedure under descript Be careful not
scratch the product.
