Safety Considerations
To reduce accidents, Health and Safety rules must be observed. Walls, ceilings and floors and
everything surrounding the UPS are best not made of inflammable materials; furthermore, the area
around the machine should be kept particularly clean so that metal dusts, iron filings or miscellaneous
metals are not sucked up inside the UPS as these could cause short circuits.
It is advisable to keep a mobile powder fire extinguisher within easy reach.
For appliances with power above 100kVA, it is a good idea to fit an automatic smoke detection
system.
Access to the UPS room should be restricted to machine service and maintenance personnel; the doors
of the premises (equipped with handle and push opening from inside) and of the UPS must be kept
closed and the keys properly looked after.
All service and maintenance personnel must be trained in emergency procedures.
Periodic tests are advisable to keep technicians trained.
New personnel must be trained before being authorised to operate the UPS.
Batteries
Siel build and supply reliable battery cabinets that do not require maintenance. The use of air-
tight lead batteries rather than the "open-vented" batteries, which smell and need specific rooms,
makes it possible to install them in cabinets adjacent to the UPS that are aesthetically matched.
If a battery room is used, the installer shall be responsible for following all applicable regulations.
Please remember that battery life is halved following an increase in temperature of 10°C above 25°C.
The batteries must be periodically recharged (at least every 6 months). SIEL S.p.A. declines any
responsibility for damage to the batteries caused by failure to comply with the above warning.
