2.4 Environment
The external battery cabinet must be installed and operated according to
the recommendations in this document. Never install the battery cabinet
in an airtight room, in the presence of flammable gases, or in an
environment exceeding the specifications.
Ensure sufficient amount of ventilation air flow preferably by natural
ventilation. Otherwise, forced (artificial) ventilation must be
implemented. Where forced ventilation is used, the air extracted from
the battery room must be exhausted to the atmosphere outside the
building.
The air inlet and outlet must be located at the best possible location to
create ideal conditions for the exchange of air, i.e. with:
•Openings on the opposite walls
•A minimum separation distance of 2 meters when openings on the
same wall
•It is recommended to locate the air inlet at the floor level and the air
outlet close to the ceiling level.
Excessive amount of dust in the operating environment of the battery
cabinet may cause damage or lead to malfunction. Always protect the
battery cabinet from the outside weather and sunshine. In order to
maximize internal battery service life time, the recommended operating
temperature range is from +20 ºC to +25 ºC. A temperature increase of
10 degrees reduces the life approximately by 50%.
WARNING
During charge, float charge, heavy discharge, and overcharge,
hydrogen and oxygen gases are emitted from lead-acid and NiCd
batteries into the surrounding atmosphere. Explosive gas mixture may
be created if the hydrogen concentration exceeds 4% by volume in air.
Ensure the necessary air flow rate for the ventilation of the battery
cabinet location.
Ensure adequate air ventilation to locations where batteries or battery
cabinets are. For the EBC-S, the minimum ventilation air flow per battery
cabinet is 6.2 m3/hour and the minimum free area of opening for inlet
and outlet is 174 cm2when natural ventilation is used. For the EBC-L,
