RISK OF INJURY!Improper mounting and installation can cause serious per-sonal injury and / or material damage. This work must onlybe performed by authorised, skilled and adequate personnelwho have received instructions providing information on thedevice and in observance of the local safety regulations.• Ensure there is enough free moving space.• Ensure orderliness and cleanliness at the working place.Loose tools lying arround are dangerous!6.2 Battery rooms, Ventilation and General require-mentsGeneral: This is a guideline only and consists of abridgementsfrom national and international standards and guidelines.See EN 50272-2 for further information. Also, observe “Ope-rating Instructions” and “Installation Instructions”.6.2.1 Temperature• AGM-batteries are developed to be operated within a widetemperature range -15°C and +55°C.• The battery-room temperature should be between +10°Cand +30°C.• The optimum operating temperature is the nominal tem-perature of 20°C.• Higher temperatures reduce the lifetime. Above 40°Cthere is a risk of „thermal runaway effects“.• Lower temperatures reduce the available capacity andprolong the recharge time.• Below approx. -8°C there is a risk of freezing, dependingon the depth of discharge. On the other hand it is possibleto use the batteries at lower temperatures, under specificconditions.• The battery temperature effects the available capacity.• The difference of temperature between the cells / mono-blocs in one battery-line has to be under 5 °C (5 Kelvin).YearsYearsTemperature in °CTemperature in °C
