If possible , the UPS and batteries should be housed in separate rooms so the running costs for cooling the equipment can be kept to a minimum .

its best . The UPS however will work without issue in a temperature of up to 35˚C . In this instance , the battery room would require mechanical cooling whereas the UPS room may be more suited to a more traditional forced air approach . The physical reduction in cubic meterage and emitted heat from the UPS would see a dramatic reduction in running costs of the air conditioning system .
6 : Consider Total Cost of Ownership ( TCO )
Research should be carried out into the cost of maintenance on an ongoing / yearly basis . Always request a price from the UPS supplier for a fixed price five year maintenance plan . Be aware that in some cases , the manufacturer ’ s maintenance plan pricing can rise sharply after the UPS warranty expires . These costs then need to be reviewed alongside the initial outlay / efficiency of the UPS in order to ensure that the package has a transparent TCO .
7 : Consider your supplier – and provision for spares
Reputation is important when choosing a supplier but it is also important to consider if they have good availability of spares and equipment . It ’ s a fact that a UPS will at some point in its working life require parts due to component failure / need for replacement . You should ensure that the supplier of choice has a complete spare parts store as well as an ex-stock holding of their current UPS .
UPS maintenance should be routine and carried out by the manufacturer or an approved third party provider .
buy an ‘ off-the-shelf ’ UPS to install themselves . But for large systems , the assistance of experts is vital as they can help in selecting the right location for the system and ensure it is installed correctly .
For bigger systems , as mentioned above , thought must be given to how the system will be expanded over time . Construction work is expensive but it is the one area in which oversizing to future proof requirements could be cost effective in the long run .
Consideration also needs to be given to the physical layout of the UPS and batteries . If possible , the UPS and batteries should be housed in separate rooms so the running costs for cooling the equipment can be kept to a minimum . For example , the battery room needs to be kept at an ambient temperature of 20 ° C to ensure the battery lifespan remains at
