Patriot PMX120, User Manual

5 

Connecting leads that are run inside buildings 
shall be effectively insulated from the grounded 
structural parts of the building. This may be 
achieved by using insulated high voltage cable. 
Connecting leads that are run underground 
shall be run in conduit of insulating material or 
else insulated high voltage cable shall be used. 
Care must be taken to avoid damage to the 
connecting leads due to the effects of animal 
hooves or vehicle wheels sinking into the 
ground. 
Connecting leads shall not be installed in the 
same conduit as the mains supply wiring, 
communication cables or data cables. 
Connecting leads and electric animal fence 
wires shall not cross above overhead power or 
communication lines. 
Crossings with overhead power lines shall be 
avoided wherever possible. If such a crossing 
cannot be avoided it shall be made underneath 
the power line and as nearly as possible at right 
angles to it. 
If connecting leads and electric animal fence 
wires are installed near an overhead power line, 
the clearances shall not be less than those 
shown in the table below. 

Minimum clearances from power lines for 

electric animal fences

1000 V to  

≤

33,000 V 

13’ (4 m)

If connecting leads and electric animal fence 
wires are installed near an overhead power line, 
their height above the ground shall not exceed 
10’ (3 m). This height applies to either side of 
the orthogonal projection of the outermost 
conductors of the power line on the ground 
surface, for a distance of: 

•

6’6” (2 m) for power lines operating at a 
nominal voltage not exceeding 1000 V. 

•

50’ (15 m) for power lines operating at a 
nominal voltage exceeding 1000 V. 

Electric animal fences intended for deterring 
birds, household pet containment or training 
animals such as cows need only be supplied 
from low output units to obtain satisfactory and 
safe performance. 
In electric animal fences intended for deterring 
birds from roosting on buildings, no electric 
fence wire shall be connected to the unit’s 
ground electrode.  
Ensure that all line-operated, ancillary 
equipment connected to the electric animal 
fence circuit provides a degree of isolation 
between the fence circuit and the supply mains 
equivalent to that provided by the unit. 
Protection from the weather shall be provided 
for the ancillary equipment unless this 
equipment is certified by the manufacturer as 
being suitable for use outdoors, and is of a type 
with a minimum degree of protection IPX4. 

Servicing 

This product cannot be serviced. Please refer to

Service of double insulated 

appliances 

In a double insulated electric fence 
charger/energizer, two systems of insulation are 
provided instead of grounding. This unit 
contains no serviceable parts.
