2.4 Environment
The accessory cabinets must be installed and operated according to the
recommendations in this document. Never install the accessory cabinets in an
airtight room, in the presence of flammable gases, or in an environment
exceeding the specifications.
Make sure that the battery cabinet room has a sufficient amount of ventilation air
flow. If possible, use natural ventilation. Otherwise, use forced (artificial)
ventilation. If you use forced ventilation, release the air extracted from the
battery room into 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. The following conditions are
recommended:
• Openings on opposite walls
• A minimum separation distance of 2 meters when openings are on the same
wall
• If possible, 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 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.
Note: For more information about the battery room ventilation requirements,
including the calculation of the necessary air flow, see: IEC 62485-2: Safety
requirements for secondary batteries and battery installations.
