Eaton Small External Battery Cabinet (EBC-S)and Large External Battery Cabinet (EBC-L) User’s and Installation Guide© Eaton Corporation plc 2015. All rights reserved. Revision: 002 Document ID: P-164000504 12 (37)2.4 EnvironmentThe external battery cabinet must be installed and operated according tothe recommendations in this document. Never install the battery cabinetin an airtight room, in the presence of flammable gases, or in anenvironment exceeding the specifications.Ensure sufficient amount of ventilation air flow preferably by naturalventilation. Otherwise, forced (artificial) ventilation must beimplemented. Where forced ventilation is used, the air extracted fromthe battery room must be exhausted to the atmosphere outside thebuilding.The air inlet and outlet must be located at the best possible location tocreate 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 thesame wall• It is recommended to locate the air inlet at the floor level and the airoutlet close to the ceiling level.Excessive amount of dust in the operating environment of the batterycabinet may cause damage or lead to malfunction. Always protect thebattery cabinet from the outside weather and sunshine. In order tomaximize internal battery service life time, the recommended operatingtemperature range is from +20 ºC to +25 ºC. A temperature increase of10 degrees reduces the life approximately by 50%.WARNINGDuring charge, float charge, heavy discharge, and overcharge,hydrogen and oxygen gases are emitted from lead-acid and NiCdbatteries into the surrounding atmosphere. Explosive gas mixture maybe created if the hydrogen concentration exceeds 4% by volume in air.Ensure the necessary air flow rate for the ventilation of the batterycabinet location.Ensure adequate air ventilation to locations where batteries or batterycabinets are. For the EBC-S, the minimum ventilation air flow per batterycabinet is 6.2 m 3 /hour and the minimum free area of opening for inletand outlet is 174 cm2 when natural ventilation is used. For the EBC-L,
