Part 1 is general requirements, and the other parts are For products covered by special requirements, their safety requirements are general requirements used in combination with the special requirements. The requirements include supplements and modifications to the corresponding clauses in the general requirements to provide complete requirements for each product. This document is the protection requirements for electrical, mechanical, thermal, fire and radiation risks when the appliance is used normally in accordance with the instructions for use. This document also covers abnormal conditions that may occur during use and considers how electromagnetic interference may affect the safe operation of the equipment. This document has taken into account the requirements specified in GB/T 16895 "Low Voltage Electrical Installations". The appliance is connected to the power supply in accordance with the electrical wiring rules. requirements are coordinated. If multiple functions of an appliance involve other parts of GB/T 4706, the other parts shall apply to the appliance separately as long as it is reasonable. Each function. If applicable, consider the impact of one function on other functions. When no additional requirements are given in other parts for hazards already included in this document, GB/T 4706.1 applies. GB/T 4706 is a standard covering appliance safety and takes precedence over general standards/horizontal standards covering the same subject. This document is used in conjunction with GB/T 4706.1-2024 "Safety of Household and Similar Electrical Appliances Part 1.General Requirements". The part marked "applicable" in the document indicates that the corresponding clauses in GB/T 4706.1-2024 are applicable to this document; the part marked "replaces" in this document indicates that the corresponding clauses in GB/T 4706.1-2024 are applicable to this document.

Safety of household and similar electrical appliances Part 91.Particular requirements for electric fence actuators1 ScopeThis chapter of GB/T 4706.1-2024 is replaced by the following. This document specifies the safety requirements for electric fence actuators. This document is applicable to fences with a rated voltage not exceeding 250V, which are used for the protection of fences in agricultural, domestic or wildlife control fences and security fences. An electric fence activator that energizes or monitors the wire. NOTE 101 Examples of electric fence actuators within the scope of this document are. ---Grid drive exciter; --- As shown in Figures 101 and 102, a battery-driven exciter that can be connected to a mains power supply; ---Electric fence actuator driven by internal or external non-rechargeable batteries. This document does not generally consider the following. --- Dangers when unattended children and disabled people use the appliance; --- Condition of children's play equipment. Note 102.Attention should be paid to the following situations. --- For equipment intended for use in vehicles, ships or aircraft, additional requirements may be required; --- National management departments may impose additional requirements on equipment. Note 103.This document does not apply to. --- Animal training collars using electromagnetic coupling; --- Apparatus intended for use in special environments where there are often corrosive or explosive gases (e.g. dust, steam or methane); --- Separate battery charger (GB/T 4706.18); ---Electric fishing device (GB/T 4706.103); ---Equipment for electric shock of animals (GB/T 4706.97); --- Appliances for medical purposes [IEC 60601 (all parts)].2 Normative referencesExcept for the following contents, this chapter of GB/T 4706.1-2024 applies.
