1027144–0001 Draft – Revision D.01 4–8 Installing IFL cables
RT installation
The IFL cable must be routed through a penetration sleeve before
it is connected to the lightning arrestor. The lightning arrestor is
attached to the penetration sleeve after cable installation.
1. Use twelve screws to attach the remote penetration sleeve
(sleeve and coupling) to the building surface at the building
penetration point. See figure 4-4.
The type of screw used depends on the roof thickness and
surface composition. The screws must hold the sleeve
assembly securely.
Note: The penetration sleeve location is site–specific and
dependent on the building penetration point. An optional
sweep, shown in figure 4-4, is available for use with the
penetration sleeve for locations where space is limited.

2. Weatherproof the penetration sleeve by applying silicone
caulk to the bolt hole areas and the surface of the sleeve
plate.
Note: Silicone caulk may not be suitable for certain types
of roofs. Choose a type of caulk that is appropriate for your
type of roof.
