UNDERSTANDING UPS SYSTEMS AND BATTERIES
Because cabinets can have locked doors, the cabinets do not have to be in battery rooms; they can be installed directly adjacent to the UPS system and/or the information technology equipment.
As mentioned earlier, batteries should be as close as possible to the UPS. The reasons are twofold: Longer cable runs mean greater potential for damage and/or short circuit. Open-rack battery rooms must be adjacent to the UPS room. Battery cabinets must be adjacent to the UPS equipment.
Open-rack battery rooms must be adjacent to the UPS room. Battery cabinets must be adjacent to the UPS equipment. Cable lengths from multiple cabinets should be kept as nearly identical as possible to prevent voltage drop variations. One cabinet should be able to hold at least one complete string of cells.
Floor Space Requirements. Preferably the UPS has to be installed close to the loads. If the distance between the load and the UPS is higher, we must consider the voltage drop based on the distance of the cable and suitable action like oversizing the cable needs to be considered.
The UPS and/or battery cabinets might be configured to look like standard computer equipment racks. There are two primary hazards of concern: electrical and fire. Open rack batteries expose potentially lethal voltage to any person coming in contact with them.

Check the dimensional information on the appropriate data sheets from the manufacturers for the floor space requirements. A clear area in front of the unit of at least 1meter should be
Reserve a clearance of at least 500 mm from the top of the cabinet for operations. Reserve a clearance of at least 500 mm from the rear of the cabinets for ventilation. If the UPS will be operated from the
The UPS cabinets use forced air cooling to regulate internal component temperature. Air inlets are in the front of the cabinet and outlets are in the top. Allow clearance in front of and above
Battery locations and enclosures are to be considered as safe from explosions, when by natural or forced (artificial) ventilation the concentration of hydrogen is kept below this safe limit.
When the incoming supply is lost, the backfeed protection device must isolate the output of any permanently connected UPS from the supply by means of separation within 15 seconds, to
How to choose the right ups? Preferably the UPS has to be installed close to the loads. If the distance between the load and the UPS is higher, we must consider the voltage drop based on
If the distance between the load and the UPS is greater, we must take into account the voltage drop based on the length of the cable and take appropriate measures, such as oversizing the
NOTE: The distance between the modular battery cabinet (s) and the UPS must not exceed 100 m. Contact Schneider Electric for installations with a longer distance.
