Edge Control Node 7000 Series Installation Guide 

       13 

For optimal antenna performance, you should place the ECN as high on the 

distribution transformer as possible.  However, most installations will require 
that the top of the ECN after installation extend no higher than the top of the 

transformer.  A typical residential transformer measures between 46 cm (18 

inches) and 74 cm (29 inches) in height.  If you place the ECN exactly even with 
the top of the transformer, you have between 15 cm (6 inches) and 43 cm (17 

inches) clearance from the transformer pad to the bottom of the ECN.  For most 

installations, this clearance is sufficient to connect the installed ECN to external 
power and the communication network. 
Installation rules also typically require that the top of the 1.9 cm or 3.2 cm (¾” or 
1-1/4”) flexible conduit should be at least 7.6 cm (3 inches) above grade level to 

prevent water ingress into the conduit.  That is, there must be at least 7.6 cm (3 

inches) of clearance from the bottom locking nut on the outside of the 1.9 cm or 
3.2 cm (¾” or 1-1/4”) flexible conduit. 

To prepare to connect the ECN to the power mains at the transformer, perform 

the following tasks: 

1.  Open the transformer cover to determine the location of an unused pre-

cored hole in the transformer pad.  This hole must be large enough to 

accommodate the 1.9 cm or 3.2 cm (¾” or 1-1/4”) flexible conduit for the 
ECN. 

2.  Use a shovel or similar tool to dig under the transformer pad to clear 

space for the conduit. 

3.  Fit the conduit up and into the hole. 
4.  Position the conduit as near to the lifting nut on the side of the 

transformer as possible.  Ideally, the conduit should be positioned 

vertically under the lifting nut.   

5.  Cut to the conduit to the approved length. 

6.  Replace the dirt below the transformer pad. 
7.  Close the transformer cover. 

After you prepare the transformer pad, you can complete installation preparation 
by performing the following steps: 

1.  Use a cable stripping tool to strip approximately 45 cm (18 inches) of the 

insulating jacket from all three conductors of the non-fitted end of the 
power cable.   

2.  Use a fiberglass or plastic cable puller tool to thread the power cable 

though the conduit that you prepared in the previous section, 

. 

3.  On the transformer side, attach the cables to the transformer so that they 

can provide power to the ECN.
