2. 2 4 2 Precautions for using the batteries Lead acid or gel batteries produce a highly explosive gas with normal use No source of sparks or fire should be present in the immediate vicinity of the batteries The batteries must be kept in a well ventilated place and be installed in such a way as to avoid accidental short circuits when connecting Never try to charge frozen batteries When working with the batteries a second person must be present in order to lend assistance in the event of problems Sufficient fresh water and soap must be kept to hand to allow adequate and immediate washing of the skin or eyes affected by accidental contact with the acid In the event of accidental contact of the eyes with acid they must be washed carefully with cold water for 15 minutes Then immediately consult a doctor Battery acid can be neutralised with baking soda A sufficient quantity of baking soda must be available for this purpose Particular care is required when working close to the batteries with metal tools Tools such as screwdrivers open ended spanners etc may cause short circuits Consequently occurring sparks may cause the battery to explode When working with the batteries all metal jewellery such as rings bracelet watches earrings etc must be taken off The current output by the batteries during a short circuit is sufficiently powerful to melt the metal and cause severe burns In all cases the instructions of the battery manufa
3. The WPC will automatically distribute the available power to the charger and the user and supply the balance of power if the load demand exceeds the fixed limit thanks to the current assistance function so called smart boost Due to the current assistance feature the battery can be fully discharged despite the presence of f the grid or the generator The average power consumed by the user must not exceed the power of the source at the risk of discharging the battery This system proves to be a decisive advantage particularly in all mobile systems boats leisure vehicles and service vehicles that are frequently connected to sources with a limited value such as a portable or camping power supply Despite a limited source all the greater power applications downstream of the WPC remain functional Despite a limited source all loads connected downstream the WPC remain functional The system will reduce automatically the charging current from its target value 1138 to 0 according to the current used at the output and the the maximum current available at the input set by the parameter 1107 The greater the current at the output the more the part of the current at the input assigned to charging the battery is reduced If the current exceeds the limit 1107 the WPC will supply the balance current from the battery The wiring of the system cable gauge must take into account this particular function which allow to have the sum of the
