1. Bring the longitudinal channel (MSP-AL-LC, 18) into place between two approx-
imately-positioned cross connectors (MSP-AL-XC, 12) and then align the parts
exactly. We recommend use of a distance gauge (not supplied as part of the sys-
tem) for this purpose.

1. As a general rule, the sleeve (MSP-AL-LS, 19) should be positioned close to a
support. The distance between the sleeve and the support should be l/4, (l = the
applicable span length).
2. Begin assembly by pushing half of the length of the sleeve (MSP-AL-LS, 19) into
the longitudinal channel (MSP-AL-LC, 18) (observe the mark on the sleeve) and
then secure it with a self-drilling screw (S-MD 43S 5.5×25, 20).

1. As a general rule, the sleeve (MSP-AL-LS, 19) should be positioned close to a
support. The distance between the sleeve and the support should be l/4, (l = the
applicable span length).
2. sliding connection between 2 longitudinal channels (MSP- L-LC,18) must
be made every 18 m (maximum) to allow for expansion.
3. Begin assembly by pushing the sleeve (MSP-AL-LS, 19) a distance of 14 cm into
the longitudinal channel (MSP-AL-LC, 18) and then secure it with a self-drilling
screw (S-MD 43S 5.5×25, 20). The distance between the end of the longitudinal
channel (MSP-AL-LC, 18) and the middle mark on the sleeve (MSP-AL-LS,19)
must be 10 mm.

1. The installation instructions issued by the panel manufacturer must be observed.
2. Position the first end clamps (MSP-EC, 21) at the ends of the longitudinal chan-
nels (MSP-AL-LC, 18) and tighten the screws slightly using a 6 mm bit or hex
key.
3. Place the PV panel on the longitudinal channel (MSP-AL-LC, 18) and slide it into
the end clamps (MSP-EC, 21).
4. Align the PV panel correctly and then tighten the screws in the end clamps (MSP-
EC, 21) securely to a torque of M
5. Fit the middle clamps (MSP-MC, 23) into the longitudinal channel (MSP-AL-LC,
18), slide them into position against the PV panel which is already in place and
tighten the screws slightly.

1. The Hilti solar park installation system is suitable for use with thin-film PV pan-
els. The installation instructions issued by the panel manufacturer must be
observed. The panels are laid out in horizontal format.
2. Fit the panel end clamps (MSP-TFL-EC, 22) into the longitudinal channel (MSP-
AL-LC, 18) and tighten the screws slightly using a 5 mm bit or hex key so that
the nut turns through 90°.
3. Position two middle clamps (MSP-TFL-MC, 24) on the upper horizontal edge of
the thin-film panel.
4. Guide the lower edge of this prepared thin-film panel into the panel end clamps
(MSP-TFLEC, 23) on the longitudinal channel (MSP-AL-LC, 18).
5. Fit the middle clamps (MSP-TFL-MC, 24) on the top edge of the panel into the
longitudinal channel (MSP-AL-LC, 18) and tighten the screws slightly using a 5
mm bit or hex key so that the nut turns through 90°.

2. The longitudinal channel must be fastened with two cross connectors (MSP-AL-
XC, 12) at each intersection. Use a 6 mm bit or hex key to tighten the screws to
a torque of M = 20 Nm.

3. Push the next longitudinal channel (MSP-AL-LC, 18) onto the previously-fitted
sleeve (MSPAL-LS, 19) until it butts against the adjoining longitudinal channel
and then secure it by driving a second self-drilling screw (S-MD 43S 5.5×25, 20).
4. Push the next longitudinal channel (MSP-AL-LC, 18) onto the previously-fitted
sleeve (MSPAL-LS, 19) but do not fasten it. An expansion gap of 25 mm must
designed to allow for temperature fluctuations of ∆T = 60 K. Please contact Hilti
remain between the ends of the longitudinal channels (MSP-AL-LC). This is
Service if greater temperature differences are to be expected during the service
life of the system.
5. Do not position the sliding expansion joint between two fastening points of the
same panel.
6. Place the next PV panel on the longitudinal channels and slide it into place under
the middle clamps (MSP-MC, 23).
7. Align the PV panel correctly and then tighten the screws to a torque of M
Nm using a 6 mm bit or hex key.
8. Subsequent panels are mounted in the same way.
9. The last PV panel in a row must be secured at its outside edge with end clamps
(MSP-EC, 21). Fit the end clamps (MSP-EC, 21) into the longitudinal channel
(MSP-AL-LC, 18), slide them into position against the PV panel, align the panel
correctly and then tighten the screws securely to a torque of M
a 6 mm bit or hex key.
6. Align the panel correctly in its final position. Tighten the middle and end clamps
to a torque of M = 15 Nm using a 5 mm bit or hex key.

7. Subsequent panels are mounted in the same way.
8. The outside edge of the panels at the end of a row must be secured with end
clamps (MSP-TFL-EC, 22).
* Certified by First Solar.
The clamps (MSP-TFL-MC, 24 and MSP-TFL-EC, 22) can thus be used with First
Solar thin-film panels (FS Series 2 laminate panels).
