4. NOT expose lead acid batteries to a lit cigarette sparks or flames because they produce flammable gasses and could explode 2 Never try to charge a frozen battery There is the danger of explosion In this case place the battery at a frost resistant location and wait until the battery has adapted to the ambient temperature Only then is the charging process started 3 Store the smart battery charger in a dry and cool place 4 Maintenance and repair must only be carried out by a qualified specialist who is familiar with the dangers involved and aware of the relevant regulations 5 This charger is designed to charge rechargeable lead acid battery NEVER CHARGE OTHER TYPE BATTERY OR NON RECHARGEABLE BATTERY 2 2 Safety when handling electrical wires If cables have to be led through sharp edged walls use a cable duct or cable bushes Do not lay any loose or sharp bent cables against electric conducting materials metal Do not pull at the cables Do not carry the charger by cable and avoid any sharp object Fasten the wirings well and lay them in such a way that there is no risk of stumbling occurring and damage to the cable can be excluded Always use socket which are earthed and secured by earth leakage circuit breaker The electical connection may only be carried out by a specialist firm Keep to the indicated minimum cable cross section Do not lay the 230 V line and the 12 V direct current in the same cable conduit cable duct DWONO
5. ARON 2 3 Safety when operating the unit 1 Do not operate the smart battery charger if the hosing or cables are damaged 2 Dry location use only 3 Take care that there is a firm position 4 Keep away from fire when charging 5 The srnart charger as well as the battery to be charged rnust be securely position so that they cannot fall over or down 6 You should connect or disconnect the battery leads when the mains supply is disconnected 7 Ensure that the smart charger is kept out of the reach of children 8 Dangers may arise which children are not able to recognize 9 Do not wear loose clothing or jewellery as these may touch the battery charger when in use 10 Operate the unit only over a socket which is earthed and secured with an earth leakage breaker 2 4 Temperature control To reduce the risk of battery explosion the smart charger monitor the battery temperature during charging In case the battery temperature exeed our present temperature 40C the smart charger will stop charging In this case two led will flash together to remind you The smart charger will restart charging automatically after the battery temperature reduce to 35C In case of charging wet battery in tropical region of which the temperature will exceed 40C please do not use temperature sensor during charging but it is strongly reccomended to monitor the charging process to avoid battery over gassing 3 0 Technical Specification Use as intended sma
