N.B.: If the return earth stake is not installed, you will not be able to test the quality of the earth connection, which is strongly
recommended before putting the system to use. You will therefore be unable guarantee that the energizer has a sufficiently effective
earth rod connection and is capable of delivering the maximum level of energy for which it has been designed when there is a large
amount of vegetation growth.
3 - Connecting the fence installation to the energizer :
Connect the fence line to the Live terminal
use FISOL GALVA designed for voltages up to 20,000 V, which can be buried as it has a protective sheath. For fencing that uses
FORCEFLEX, it is preferable to use FISALU dual cable.
Connect the main earth installation to the earth terminal
FISOL GALVA or FISALU type from LACME.
Likewise, connect the return earth rod to the earth check terminal
Ensure that all the connections make good electrical contact.
If you have to use different metals and need to connect them, regularly protect this potential weak spot of the installation against
oxidation by applying household grease.
4 - OPTIONAL - Installing loss simulation between the fence line and the earth:
It is necessary to simulate a significant loss to test the quality of the earth connection and that this operation is best repeated at least
once per year, for example in the dry season, it is advisable to set up such a simulator for use at any time.
To do this, drive a 1 metre earth stake into the soil at around one hundred metres from the energiser earth connections including the
return test earth stake. Connect it with FISOL GALVA or FISALU (high voltage cable with double insulation) to a LACME circuit breaker
connected to the fence line(as shown below). You will thus have a permanent installation allowing you to create a loss at any moment
and thus test the quality of the earth installation necessary for your energiser to operate correctly.

5 - Carrying out a earth quality test:
This test checks the correct working order of the installation of your fence system. It involves simulating a large (parallel) loss at a
distance from the fence. When this loss becomes big enough, the left-hand blue LED starts to flash strongly. At this point, if the earth
connection is not good enough, the right-hand red LED will light up. The aim is then to improve the quatity of the earth connection so that
the right-hand red LED finally goes out.
To achieve this, you must carry out the operations described in sections 2 and 4 above. You can then carry out the following steps :
- Disconnect the energiser from the mains power supply.
- Create a parallel loss (e.g. if you have fitted the simulator specified in section 4, set your circuit breaker so that it
creates a short circuit.
- Reconnect the energizer and wait for 2 minutes until the system stabilises.
- After 2 minutes, check that the blue LED is on (it shows a large loss on the fence).
- Follow the instructions given in A or B below, according to the case.
If A - The right-hand red LED is off :
- Well done ! Your earth stake installation is good
- Take off the parallel loss (e.g. if you have fitted the simulator specified in section 4, set your circuit breaker so that it
goes back top the fence line).
- Your installation is now in the best operating condition.
If B - The right-hand red LED remains on :
- Your earth stake installation needs to be improved.
- Disconnect the energizer.
- Add another earth rod to the installation (for difficult soil conditions, sometimes up to 10 earth stakes are required to achieve
the necessary earth quality).
- Reconnect the energizer and wait for 2 minutes until the system stabilises.
- Check that the right-hand red LED is off.
If this is the case, refer to paragraph A above. Otherwise :
- Repeat operation B as many times as necessary until the red LED switches off.
