Dear Customer,
The eBoxx A-letterbox modular system facilitates a modular assembly. The assembly is carried out using the
BURG-WÄCHTER Terzo posts. The Terzo posts can be cast in concrete or xed to a concrete foundation by means
of the BURG-WÄCHTER Terzo base.
The assembly instructions are to be read thoroughly prior to assembly. These assembly instructions will guide you
through the following steps:
Step 1: Determination of the type of system required
Step 2: Selection of the appropriate crossbar
Step 3: Planning the slot height of the letterboxes in the system combination
Step 4: Drilling the boreholes specically for the system being assembled
Step 5: System assembly
Table 1: Type of assembly
Note:
These instructions describe the assembly of a system with several letterboxes. To assemble a system consisting of A-boxes
and parcel boxes, follow the instructions in the relevant instructions. The number of letterboxes must not be less than
six vertically mounted A-boxes when installing the A-boxes in the system combination. Please select another model for
systems with less than 6 letterboxes.

Pre-drilling the system elements is required for all types of system assembly. Depending on the system combination
intended, the next step is to drill the boreholes in the A-letterboxes. The following tools are required for drilling
theboreholes.
Table 6: Tool for drilling the eBoxx A-letterboxes
The elastic ring supplied serves as scratch protection and should be placed on the drill bit during all drilling work on
the system. Refer to Table 7 for the drilling positions required for your system combination. For this purpose, the outer
surfaces of the letterboxes are supplied with centre points so that you can position the drill directly without slipping.
Note: Boreholes are already pre-drilled in the bottom of the A-letterboxes at the factory. Use the rubber plugs supplied
toclose these holes if no other letterboxes are to be mounted below the A-letterboxes.

Tools
(Example: Assembly of two A-letterboxes
The system can be assembled once the individual system elements have been pre-drilled.
The assembly set supplied with the A-letterbox is required to assemble the system (see Table 8 and Appendix A)
Table8 illustrates the assembly set and the tools required. It provides an illustration of the assembly of an A-letterbox.
Allcombinations and connection points that have been pre-drilled in accordance with Step 4 or Table 7 are screwed
together in the same way.
Attention: First screw the letterboxes together vertically, i.e. one below the other. Then screw the letterboxes together
horizontally, i.e. sideways to each other.

The entire system must be pre-assembled for the installation of the system with Terzo posts, cast in concrete or screwed
on with Terzo bases. This assembly sequence must be observed.
Depending on the intended combination (Table 3 - 5) and after drilling the required boreholes in accordance with
Table7, the letterboxes must be screwed to a suitable underlay (cardboard or similar) using the mounting set supplied
(seeTable8). The underlay is to protect the system from scratches or other damage.
The following table illustrates how to pre-assemble a 24 A-box system.
Table 9: Pre-assembly of the system
The Terzo posts are pre-drilled for the use of self-tapping screws. For a system assembly with several A-boxes, some
boreholes must be enlarged so that the rivet nuts used for the system can be inserted. The following pages describe
which of the existing rows of boreholes R1-R24 on the Terzo post must be drilled out for the intended system using a
6.0mm drill. Table 11 provides an overview of the boreholes pre-drilled at the factory. Remember to slide the tube ring
onto your drill bit to prevent damage to the post when drilling.
Note: A 6.0 mm drill bit is required for drilling on the Terzo post and a 5.0 mm drill bit is required for drilling on the system
(A-letterbox).

The assembly set shown in Table 13 and the corresponding tools are required to assemble the system with the
Terzoposts.
Table 13: Assembly set for connecting the system to the Terzo post
Complete the following steps to connect the pre-assembled
system and the crossbar to the Terzo post:
1. Hand-tighten the cylinder screw and rivet nuts on the
system and the crossbar. For this purpose, use the holes
drilled on the system and the Terzo post in accordance
with Table 12 in Step 5.1.2. Optionally, a crossbar can be
attached to a system in accordance with Table 12. In this
case, repeat these steps for the crossbar as well.
2. Place the pre-assembled system carefully on its upper surface. We recommend covering the oor with board/
cardboard beforehand to protect the system from scratches and damage. Screw the Terzo posts and, if installed,
thecrossbar to the system as shown. Tighten screws, be careful not to over-tighten!
Over-tightening can damage parts and considerably impair the retention force.
Note: The assembly is carried out with a crossbar in the illustrations below. If you do not want to use a crossbar,
please skip the corresponding steps.
When assembling the system with Terzo posts, it is essential to rst screw the system together and then t the Terzo posts
to the system.
• Continue to Step 5.1.4 to install the system with the optionally available Terzo bases on a concrete foundation.
• Continue to Step 5.1.5 to assemble the system by casting the Terzo posts in concrete.
The following steps refer to the assembly of the system using the optionally available Terzo bases, which connect the
system to a concrete foundation.
Plan an area of at least 500 x 500 mm for the concrete foundation with a depth of at least 800 mm for each Terzo post,
depending on the local frost threshold. The foundation size is to be increased depending on the local condition of the soil.
It is recommended to spread a layer of crushed stone underneath the concrete foundation. Backll the excavated area
with concrete and compress. Note the minimum period of time for the hardening of the concrete before the foundation
and the system is fully loaded. Concrete with a minimum compressive strength class of C25/30 is recommended.
Assembly of the system on an insecure foundation is not permitted. When laying the foundation, ensure that it is
horizontally level. Check the evenness of the foundation with a spirit level before assembly. If the foundations are
separated, also ensure that the levels are aligned with each other.
1. Mount the Terzo bases using the three M8 countersunk screws supplied:
2. Set up the system with at least two people. Do not lift/carry using the Terzo posts when setting up!
Note: Align the system vertically and horizontally using a spirit level.
Then mark three boreholes per base on the concrete foundation and place the system to one side again. Ensure that
the system cannot fall over, otherwise lay the system on its back wall again (on cardboard or similar). Drill the marked
holes at least 10 mm deeper than the dowel length. Insert the dowels so that they are ush with the surface.
3. Use at least two people to align the system over the drilled holes. Ensure that the system cannot be tilted or twisted.
Tighten both bases rmly using three of the M8 cylinder screws supplied.
Tighten the screws alternately to prevent tilting.

Plan an area of at least 500 x 500 mm for the concrete foundation with a depth of at least 800 mm for each Terzo post,
depending on the local frost threshold. The foundation size is to be increased depending on the local condition of the soil.
The following tools are required:
According to step 5.1.3, the system must always
be cast in concrete after the entire system has
been pre-assembled. It is not permitted to rst
assemble the Terzo posts with the crossbar, set
them in concrete and then screw on the system.
It is recommended to spread a layer of crushed
stone underneath the concrete foundation.
Position the Terzo posts in the ground to a depth
of approx. 500 mm. Use stones if necessary and
align the system vertically and horizontally using
a spirit level as illustrated. Then provide sucient
support for the system. Backll the foundation
pit or hole with concrete and compress. Support
the system without clearance for the time the
concrete is hardening and safeguard it against
falling over. Note the minimum period of
time for the hardening of the concrete before
the system is fully loaded. Concrete with a
minimum compressive strength class of C25/30
isrecommended.
