Perimeter Wire Setup 
1.0  Where To Start 
In  order  to  determine  the  best  location  to  begin  the  setup,  it  is  best  to  first  make  some  basic 
decisions  based  on your lawn. For each zone that is set up, allow  for placement of one 
Perimeter Switch for that zone.  Find a convenient spot outside the perimeter of each zone that 
is relatively easy for you to access. A spot sheltered from the elements is preferred
1.1 Using The RoboRuler 
There  are  two  basic  measurements  that  are  used  on  the  RoboRuler.    The  shorter  distance  is 
used along perimeter edges where the area outside the immediate perimeter (about 12 inches/30 
cm)  is  free  of  obstacles  and  is  the  same  relative  height  as  the  perimeter  edge.    The  longer 
distance  is  used  along  perimeter  edges  where  the  area  outside  the  immediate  perimeter  has 
obstacles or differences in the height along the perimeter edge. See Figure 1.1. 
1.2  Starting The Perimeter Wire 
Tear  out  the  perforated  center  piece  on  the perimeter  wire  box.    Puncture  the  plastic  covering 
with your finger and feel around inside the center of the wire spool for the end of the wire.  Pull 
the wire end out of the box.  The box is designed as a dispenser for the wire so do not remove 
the  wire  spool  from  the  box.    After  reviewing  the  illustrations  and  instructions  in  the  following 
pages you will be ready to lay out the perimeter wire and start pegging it to the ground.  Figure 
1.2 
Leave enough wire at the beginning, where the Perimeter Switch is going to be located.  Use the 
RoboRuler  to  help  guide  you  on  placement  of  the  wire  along  the  perimeter.    Use  a  minimum 
number  of  pegs  at  this  point, as  you will want to test  the wire position at the end of  the setup. 
See Section 2.5 for details on testing the setup.
