System Overview - Hilti Solarpark Instructions De Montage

Assembly aids
For alignment of the longitudinal channels (MSP-AL-LC, 18) Hilti recommends use
of a distance gauge. The distance (spacing) between the longitudinal channels
depends on the type of panel used and the layout arrangement. The assembly instruc-
tions issued by the panel manufacturer must be observed.

System overview

The parts list shows all the necessary components of the system.

The distance between the support posts (MSP-HDG-RP, 1) and the depth of embed-
ment in the ground depends on the results of the structural analysis and the pro-
ject-specific subsoil assessment.

1. Position and align the drilling template or insulating plate (MSP-AL-BPI, 2) on
the foundation and mark the holes.
2. Drill the holes for Hilti M12 or M16 stainless steel anchors (4). The anchor to be
used depends on the results of the structural analysis.
3. Position the insulating plates (MSP-AL-BPI, 2) on the concrete foundation.
4. Place the baseplates (MSP-AL-BP, 3) on the insulating plates and anchor them
securely.
5. Place the front and rear support posts (MSP-AL-SP, 5) on the baseplates (MSPAL-
BP, 3).
6. Insert an (M12×100 A2-70, 6) hex. bolt in the outside hole in the rear support
post (MSP-AL-SP, 5) and two hex. bolts (M12×100 A2-70, 6) in the front sup-

1. Excavate the foundation holes or trenches: The dimensions of the foundations
depend on structural design criteria, the geological and climatic conditions and
must be specified individually by the structural engineer responsible for the pro-
ject. The minimum dimensions for foundation excavations are: diameter 40 cm,
depth 55 cm.
2. Prepare the cast-in profiles: Insert and secure a length of steel reinforcing bar
(10mm diameter) through the lower holes in the profile. The bar should be at
least 150 mm long or in accordance with the structural requirements specified
by the engineer responsible.

1. Align the adapter plate (MSP-AL-EAA 16, 27) on the earth anchor (not supplied
by Hilti) and use a suitable M16 bolt to fasten it in accordance with the specified
structural design requirements.
2. Place the base plate (MSP-AL-BP, 3) on the adapter plate (MSP-AL-EAA 16, 27)
and secure it at both sides with a bolt (M12×40 A2-70, 28), washer (A13/24 A4,
29) and nut (M12 A4-70, 7). Tighten to a torque of M
3. Fit the front and rear support posts (MSP-AL-SP, 5) on the base plates (MSPAL-
BP, 3).
4. Insert a hex. bolt (M12×100 A2-70, 6) through the rear support post (MSP-AL-
SP, 5) from the outside and two hex. bolts (M12×100 A2-70, 6) through the front

1. Slide two comfort connectors (MSP-AL-CC, 9) or two basic connectors (MSP-
AL-BC, 10) into the slots in each transversal channel (MSP-AL-TC, 11).

1. Preparation of the required cross connectors (MSP-AL-XC, 12): Two cross con-
nectors (MSP-AL-XC, 12) are required at each planned intersection of the longi-
tudinal channels (MSP-AL-LC, 18) and transversal channels (MSP-AL-TC, 11).
2. Insert the cross connector (MSP-AL-XC, 12) in the transversal channel (MSP-
AL-TC, 11) and turn it clockwise through 90°.

If the system is footed on concrete foundations, Hilti recommends use of a drilling
template for marking the positions of the holes to be drilled.
The insulating plate (MSP-AL-BPI, 2) is suitable for this purpose.
Use of a template ensures that the distance between the holes in the concrete foun-
dation is exactly right.
The items supplied may vary depending on the system ordered.
The ramming profile (MSP-HDG-RP, 1) may be used in non-corrosive or mildly cor-
rosive subsoils (subsoil class I as per DIN 50929).

7. Fit the support channel (MSP-AL-SC, 8) at the foot of the rear support post, insert
a hex. bolt (M12×100 A2-70, 6), screw on a nut (M12 A4-70, 7) and tighten to a
torque of M
8. Bring the support channel (MSP-AL-SC, 8) into position on the front support
post, insert hex. bolt (M12×100 A2-70, 6), screw on a nut (M12 A4-70, 7) and
tighten to a torque of M
3. Steel reinforcement must be incorporated in each foundation in accordance with
the specified structural requirements.
4. Pour the concrete for the foundations (concrete of at least the C20/25 grade or
in accordance with the specified structural requirements.
5. Place the profile (MSP-HDG-CI, 31) in the trench, pour the remaining concrete
and use a suitable means to compact it. While doing so, check the vertical, hor-
izontal and axial position and alignment of the cast-in profiles.
