b Installing the BTS3900C Cabinet on a Wall
1. Mark off four fixing points
according to the holes on the
backplane.
2. Use a percussion drill to drill holes at
the fixing points, and then install
expansion bolt assemblies.

3. Use expansion bolt assemblies to install the backplane onto the wall.
Wear safety goggles or take other measures during the drilling to protect your eyes from dust.
Ensure that the depth of the holes is between 52 mm and 60 mm. If the depth of the holes is out of the range
of 52 mm and 60 mm, the expansion bolt assemblies cannot be fastened. The requirements for the depth of
the holes that are drilled on the stand and on the wall are the same. Use a cleaner to clear the dust inside and
around the holes. Then, measure the inter-hole spacing. If the inter-hole spacing is too wide or too narrow,
locate and drill holes again.

to one of the lower brackets. 3. Fix the lower brackets and backplane to the metal pole, and then use bolts to fix
the backplane to the upper bracket.
There is one outer hole and one inner hole for
installing one tightening pole. The diameter of
the metal pole determines which one of the two
holes is to use.
