NOTE
Vertical mounting is propositional. Tilted mounting
is permitted, but will reduce heat dissipation and
result in self-derating.
4.4 Preparation
Below tools are needed before installation:
Installation tools:
Crimping plier for binding post, crimping plier for
RJ45 and RJ11, screwdriver, allen wrench and Ø8
driller.
4.5 Installation steps
1. Drill holes in the concrete wall with Ø8 driller
according to the size of bracket. The size is
shown in following figure. Keep drilling verti-
cal to the wall, and don’t shake when drilling
to avoid damage to the wall. The depth of the
holes should be about 45 mm and should be the
same. After removing the dust in the holes, mea-
sure the net depth of the holes. If the depth is
more than 50 mm or less than 40 mm, the expan-
sion tubes wouldn’t be installed and tightened.
NOTE
When the wall is made of a different material (other
than concrete), the installation should be done
using adequate mounting material. Sunways recom-
mends always using stainless steel screws.

2. Clean all dust outside/inside the hole and mea-
sure pitch-row before installation. It need repo-
sitioning and drilling holes if the hole with much
error. Then put wall plug into the hole vertically
(shown in the following figures), use rubber
hammer to tap the pipe into the wall completely.
After that, mount the metal bracket to a con-
crete wall. The screws should be mounted in the
4 holes present in the bracket (shown as pos A in
the following figures).
