operation of the appliance under the following conditions:Battery chargers for charging lead- acid batteries, and other battery chargers having a rated DC output current not exceeding 20 A,are connected to the circuit of Figure 101. The variable resistor is adjusted so that the current in the circuit is the rated DC output current when the battery charger is supplied at rated voltage.
When the charging current is controlled by the state of charge of the battery, the variable resistor and the capacitor are replaced by a discharged battery of the type and having the largest capacity specified in the instructions.
Other battery chargers are connected to a discharged battery of the type and having the largest capacity specified in the instructions.transformer, the input winding of which is electrically separated from the output winding by an insulation at least equivalent to double insulation or reinforced insulation, that is intended to supply a battery charging circuit having an output voltage not exceeding 120 V ripple-free direct current
Note 1 to entry:Ripple-free means an r.m.s. ripple voltage not exceeding 10 % of the DC component.
The instructions shall
一specify the types, the number of batteries and the rated capacity of the batteries that can be charged;
一 include a warning against recharging non-rechargeable batteries;
一state that during charging, the battery must be placed in a well-ventilated area (for chargers for vented batteries);
一 state that the battery charger must only be plugged into an earthed socket-outlet (for portable class I battery chargers for outdoor use);
一explain the automatic function, stating any limitation (for automatic battery chargers).
The instructions for battery chargers for charging automobile batteries shall include the substance of the following:
一the battery terminal not connected to the chassis has to be connected first. The other connection is to be made to the chassis, remote from the battery and fuel line. The battery charger is then to be connected to the supply mains;
一after charging, disconnect the battery charger from the supply mains. Then remove the chassis connection and then the battery connection.AS NZS 60335.2.29 pdf free download.
