Ideally the ground block should be bonded to the roof ground network, a metal cold
water pipe, structural steel, or metal electrical conduit. Use #10-AWG solid-copper wire
(minimum). Green insulation is preferred. Alternatively uninsulated #8-AWG aluminum
may be permitted. Be sure to check national and local code requirements.
Connect the ground wire to the cold water pipe or alternative using an appropriate
crimp-on ring or lug connector. Ground conductor and termination hardware are not
supplied.
Warning! Failure to properly ground the DU will leave the unit and building vulnerable to
damage from lightning strikes. Check local building and electrical code requirements and
comply with both local and national regulations.
Ideally the DU ground wire should be bonded to the roof ground network. For roofs
without such a network use a metal cold water pipe, structural steel, or metal conduit.

To mount the DU indoors:
1. Use the mounting bracket as a template and mark the hole locations.
2. If the mounting is in a solid wood surface, or a stud covered by drywall, drill a 5/32
inch diameter hole. Mount the unit with 2 inch wood screws.
or
If the mounting is in drywall, drill a ¼ diameter hole and insert an anchor. Mount the
unit with 1/2 inch pan head screws.
3. Attach cables to the wall using tie wraps and mount directly to the wall where
possible (using 1/2 inch pan head screws). If an anchor is required drill a 3/16 inch
diameter hole, insert the anchor, and fasten with 1/2 inch pan head screws.
