Page 21: Ballast carrier
Note: The ballast stones are not a constituent part of the Hilti MSP-FR
installation system. Ordinary concrete blocks with widths of 20, 25,
40 and 45 cm can be used as ballast.
Note:
Before screwing in place, check the position of the ballast carriers
in the PROFIS Solar software.

Picture , , : Ballast rail (MSP-FR-BR)
1. Position the ballast rails (MSP-FR-BR) on the north side of the central
support (MSP-FR-SM).
Page 22: East-west cable ducts
Note: The cable ducts and guards are optional elements and are used
to guide string lines out of the panel array. To achieve the best
possible cable routing and protect the cables from the effects of
the weather, Hilti recommends that genuine Hilti cable ducts and
guards are used.
Page 23: North-south cable duct
Picture 1 , 2 , 3 , 4 : North-south cable duct (MSP-FR-CT)
1. Place the cable ducts (MSP-FR-CT) for the north-south connection in the
desired position, such that the ducts will be subsequently covered by PV
modules. Do not install ducts on the outside edge of an installation block.
Page 24/25: PV panels
Note:
Only fit the panels in a landscape format.
Picture 1 , 2 : PV panels
1. Check the installation instructions of the panel manufacturer.
2. Place the PV panels onto the supports (MSP-FR-SN).
3. Ensure that the following points are correctly observed:
– Connection between north support (MSP-FR-SN) and PV panel:
Tolerance 4–10 mm.
– The south connections lie up flat.
– Other sides of the connection: Tolerance 0–2 mm.
Page 26: Electrical potential equalization and wind protection
Note: In order to integrate the system into the electrical potential equali-
sation system of the PV installation, each block must be separately
connected with an earth clamp (not included in the delivery).
Note: each PV panel must be electrically connected.
Picture A1 , A2 : Earthing without wind protection
1. Turn screw (MSP-FR-GS 6x60) into the drill hole provided (see earth
symbol). Tightening torque: 10 Nm
✔ The panel frame is electrically connected to the mounting structure.
Page 27: lateral wind protection
Note: Under certain external conditions, additional wind protection (MSP-
FR-WDW or MSP-FR-WDE) is necessary along the short sides of
the panel. Information on the wind protection required can be found
from the report in the PROFIS Solar software.

2. Position the ballast rails so that the perforated side points towards the other
ballast rail.
3. Position the ballast rail according to the established dimensions.
4. Fix each ballast rail in place with 2 screws (MSP-FR-S M6x16).
Tightening torque 5 Nm.
5. If there are several panels, screw the ballast rails together so that they
overlap.
Note: Always lay the ballast on the centre edge.
6. As far as possible, position the ballast centrally.
Picture 1 , 2 : East-west cable duct (MSP-FR-CT)
1. Place the cable duct (MSP-FR-CT in the desired position.
2. Fix in place with 2 screws (MSP-FR-S M6x16). Tightening torque 5 Nm.
3. Hook a cable clamp (MSP-FR-CH) on the top and bottom of the cable duct.
2. Fit to the support with 2 screws (MSP-FR-S M6x16). Tightening torque 10 Nm.
3. Hook in the cover plate (MSP-FR-CTC) and press down until a click can be
heard.

Picture , : End clamps (MSP-FR-EC)
4. Attach the end clamps (MSP-FR-EC) to the outer supports.
Tightening torque: 10 Nm
Picture B1 , B2 : Centre clamps (MSP-FR-MC)
5. Use centre clamps (MSP-FR-MC) for connections between 2 PV panels.
Tightening torque 10 Nm.
Picture 3 : Ensure that the following points are correctly observed:
– Depth of coverage of clamp and panel frame: at least 7 mm
– Contact surface width of the support on panel frame: at least 20 mm
Picture B1 , B2 : Electrical potential equalization with wind protection
Note: Information about which panels require wind protection along the
long sides of the panel (north side) can be found from the report in
the PROFIS Solar software.
2. Attach the wind protector in the correct position on the north carriers and
hook in at the bottom so that it cannot be moved.
3. Fix in place with 2 screws (MSP-FR-S 6x60). Use the drill hole with the earth
symbol. Tightening torque: 10 Nm
✔ The panel frame is electrically connected to the mounting structure.
Picture 1 , 2 : lateral wind protection
1. Position the wind protector correctly on the east and/or west sides.
2. Fix in place with 3 screws (MSP-FR-S M6x16). Tightening torque: 10 Nm
