Basic safety instructions

The following basic safety instructions and warnings form an essential part
of these instructions and are of fundamental importance when handling this
product.
en
• Working clothing which complies with national regulations must be worn.
• Applicable industrial safety provisions must be observed.
fr
• Ensure that all electrical work is only carried out by an electrically qualified
it
specialist. Observe all relevant regulations.
es
• The presence of a second person who can provide help in the event of an
accident is obligatory during the entire installation procedure.

Operating conditions

The MSP-FR installation system is designed to withstand all prevailing wind and
snow load scenarios.
The Hilti MSP-FR installation system is designed for the following panel formats:
• Length 1450–1515 mm and 1550–1680 mm and 1945–2005 mm
• Width 790–840 mm and 950–1010 mm and 1040–1095 mm
The Hilti MSP-FR installation system is suitable for environmental conditions
within the range of normal environmental corrosivity (distance of at least 1
km from sea coasts). The system may also be installed in a C4 environment
if specific maintenance tasks are adhered to (guidelines/instructions available
from Hilti on request).
Substrate
The Hilti MSP-FR installation system is exclusively suitable for foil roofs with a max.
inclination of 5°. The MSP-FR installation system is not suitable for green roofs.

Installation preparations

Preparing the roof
1. Before planning the installation, an expert assessment of the roof must be obtained
in order to determine the suitability of the roof for supporting a PV system. The
roof must also be of an adequate design standard and constructed correctly.
2. Testing the suitability of the roof:
– Sufficient support for the additional loads arising from the installation frame
including panel, cable ducts, cables, ballast, snow and wind pressure
– Consideration of the permissible bearing pressure of the insulation
– Compatibility of the roof skin with the load distributor
– If determined necessary, use the MSP-FR-AP
– Adequate drainage and the avoidance of water pooling.
3. Check the roof for damage. Clarify possible damage and its repair with the
building owner before commencing with the installation.
4. The foil roof must be thoroughly clean as well as free from snow and ice.
5. Check that the plans are compatible with the structural findings before
starting the installation.
If deviations are found from the proposed operating conditions, contact the Hilti
service department.
Installation
Page 19: Supports and load distributor plates
Note: There are 2 different load distributor plates (MSP-FR-LDP).
You can find the load distributor plates required for installation from
the report in the PROFIS Solar software.
Picture A1 : South support (MSP-FR-SS)
1. Slide the load distributor plates (MSP-FR-LDP) from below over the south
plate (MSP-FR-SS) until the plate is central and audibly snaps into place.
Page 20: Rails
Note: Before fastening the rails, check the required dimensions of the
scale setting in the report of the PROFIS Solar software.
Picture 1 , 2 : North-south rails (MSP-FR-CNS)
Note:
Use the short rails (MSP-FR-CNS) for the north-south connection.
1. Slide the rail into the groove at the side of the support (MSP-FR-SS).
2. Align the rail according the established dimensions.
3. Fix each rail in place with 2 screws (MSP-FR-S M6x16). Tightening
torque 10 Nm.

• Keep a copy of these installation instructions to hand in the immediate
vicinity of the system for use by the assembly personnel.
• The system is designed in such a way that it can only withstand the prevai-
ling location-specific wind conditions after installation has been completed.
During the entire installation procedure, secure the sections which have not
been completed as well as materials which have not yet been installed to the
roof in accordance with the prevailing regulations.
The Hilti MSP-FR installation system can only be used for framed photovoltaic
panels which allow a clamp in the corner area of the short sides.
▶ Check usability with the panel manufacturer in each case. Hilti can provide a
list of the approved panels on request.
▶ Dimensioning the flat roof installation system (MSP-FR), especially the
calculation of the additional ballast required, must be carried out for each
individual project.
Both the cables and the cable ducts are not taken into account when calculating
the total load of the roof.
▶ Loads arising from cables and cable ducting are added manually.
The MSP-FR-LDPs (230 and 380) are not considered stiff elements in the
design calculations. Permanent deformation may be observed over time and this
has no impact on the functionality of these items.
The general conditions and structural design assumptions must be examined
on site by the customer. For more detailed information, contact the Hilti service
department or a local structural engineer.
Material placement
1. Carefully plan how the materials are laid out on the roof in order to enable
easy installation.
2. Check that the materials are evenly distributed in order to guarantee a
balanced roof load.
3. Position the material so that the installation is not impeded.
Marking the rows
1. Familiarise yourself with the PROFIS Solar planning papers and, as can be
seen from these, how the roof is divided into blocks of PV panels.
2. Mark each of the first rows of the blocks on the roof and start arranging the
panels in a block pattern.
Tools required
• Torque wrench and battery-powered screwdriver, such as the Hilti SF 14-A
• Size 30 Torx attachment

2. Same procedure as with south support.
Picture C1 : North support (MSP-FR-SN)
3. Same procedure as with south support.
Place all supports with load distributor plates roughly according to the planned
position.
Picture 3 , 4 : East-west rails (MSP-FR-CEW)
Note:
Use the long rails (MSP-FR-CEW) for the east-west connection.
4. Slide the rail into the upper groove of the support (MSP-FR-SM).
5. Align the rail according the established dimensions.
6. Fix each rail in place with 2 screws (MSP-FR-S M6x16). Tightening
torque 10 Nm.
