This clause of IEC Publication 1011 is applicable except as follows:
This standard applies to battery-operated electric fence energizers not designed for connection to the supply mains and having rated supply voltage not exceeding 36 V d.c.
Examples of electric fence energizers within the scope of this standard are.
- electric fence energizers operated by non-rechargeable batteries either incorporated or separate;
- electric fence energizers operated by separate accumulators only;
- electric fence energizers intended to be connected to a battery charger not designed for connection to the supply mains;
- electric fence energizers incorporating a dry battery or an accumulator which can only be recharged when removed from the energizer.
Electric fence energizers may incorporate electronic circuits or electronic components.
Requirements for battery-operated electric fence energizers suitable for connection to the supply mains, for example those incorporating batteries and facilities for charging these batteries from the supply mains, are given in IEC Publication 1011-1.
