Electric Fences Not Only Control Domestic Animals and Livestock, but Also Have Many Important Uses, Including Confining Wild Animals Type Groups of Animals, Allow Crop and Forage Rotation, Isolate Animals from Trees, Rivers, Roads and Damaged Land, Electric Fences Have Enabled Newer Grassland Management Techniques, Better Grassland Management is Better for Pastoralists , Fixed and Movable Electric Fences Are Used for Grassland Zoning to Ensure the Uniformity of Grassland Grazing and Animals on the Grassland; Only in This Way Can the Forage Keep Freshness and Good Palatability, As Well As Maintain the Appropriate Height of the Grass, and Ultimately Play a Role in Increase Milk and Meat Production in Grasslands. Function: (1) Dc12v: 12∨ Dc Input Socket, Need to Use 12v Power Supply of Not Less Than 2a, You Can Also Use the Battery Cable Provided with the Machine to Directly Use 12v Battery Power Supply, if You Use 220ν Ac Power, You Need to Use a Power Converter (the Machine is Already Equipped) , 220 Ac Power Must Be Equipped with a Leakage Protector, or a Small Current Leakage Protector Installed Separately for the Power Converter of the Machine. (2) Pulse Adjustment: the Pulse Cycle Adjustment Knob, Rotate This Knob to Adjust the Pulse to Form a Discharge Cycle Between 0.75 Seconds and 0.3 Seconds (3) Alarm: Alarm Output Socket, Output 12v when Alarming, Used to Connect Alarms with Power Less Than 10w, if You Need to Connect Alarms Larger Than 10w, You Need to Connect an External Relay Control Power Supply to Supply Power to the Alarm. Directly Connecting an Alarm with a Value Greater Than 10w Will Burn out the Circuit Inside. Package List 1 x Electric Fence Charger1 x Power Adapter 1 x Battery Clip (Pair) 1 x Alarm 1 x User Manual Note 1. This machine must use the power supply of the single‑phase leakage protector, or install the single‑phase leakage protector separately. 2. Do not let the elderly and children with limited mobility get close to the high‑voltage power grid. 3. The ground wire must be well connected. The ground wire is a discharge circuit and plays a role of safety protection, so it must be installed firmly. Open circuit or serious rust on the connector may easily cause damage to the machine or trip of the leakage protector. 4 This machine should not be used in a humid environment, it should be installed in a dry and ventilated place. Special Note: Anyone who does not use the ground wire and leakage protector will cause damage to the machine or electric shock to people and animals, and the consequences will be at their own risk. 5.
