Peak voltage: The device’s maximum voltage measured in volts.
Pulse energy: The energy (joule = watt x sec.) that is effectively available to the enclosure.
Charging energy: A theoretical measure of energy, measured inside the actual device.
Theoretical fence length: The load = number of km of fencing wire at which the device’s voltage output has fallen to 1,500 volts. This disregards any kind of leakage (vegetation, moisture, faulty insulators, etc.).
The values may vary with the mains voltage where mains-powered devices are concerned.
Safety. All ELEPHANT electric fence devices conform with the latest European safety requirements, the European standards EN 61011/EN60335-2-76.
Power consumption. Mains-powered devices are cheap to operate – from approx. 1 watt for the ELEPHANT Mini M1 to approx. 15 watts for the ELEPHANT M115/M115-D. For battery-powered devices, please refer to information about operating times for the individual models.
Installation. To make optimal use of the fence device, it is a precondition that the earth connection is in working order. The earth rod should be made of galvanised steel, and the connections to this and to the enclosure should be made of galvanised fencing wire or high voltage-insulated electric wire cable/earth cable Please note: the earth connection must never generate a shock. If it does, it must be rectified with a longer earth rod or more earth rods.
Fencing wire, etc. For permanent fences it is usually best to use ordinary galvanised fencing wire. The electrical resistance in this (ohms per metre) is small and of no practical significance, even in long enclosures. (You must, however, be careful when joining wires). Polywire and polytape, which are easy to install, are not as robust, and you should make sure that the electrical resistance (ohms per metre) here is as low as possible.
Choosing a device. Comparing the form shown with the fence lengths stated for each device will give you an overview of the relevant options.
