KEY WARNINGS

Solar modules generate electricity as soon as they are exposed to sunlight. Hence, they
are constantly electrically ‘live’. Fully-insulated plug and socket contacts provide protection
in case of physical contact. However, the following rules must be observed in contact with
solar modules:

Do not place any electrically conductive items in the plugs or sockets.

Do not install solar modules or power cables if plugs or sockets are wet.

Be extremely careful when carrying out any work on power cables.

Do not conduct any electrical installation work where there is moisture.

Even when there is only a small amount of light available, serially-connected solar modules
may still use very high direct current voltages, and contact with these can be lethal. Please
be aware of the secondary injuries and damage caused by electric shocks.

Even when switched off inverters can still pass on powerful electrical charges on contact:

Take special care when working with the inverter and power conduits.

Before further work is conducted, it is essential to adhere to offline intervals recommen-
ded by the manufacturer once the inverter has been switched off to ensure the power in
high-voltage components has time to discharge.

Please adhere to all installation specifications provided by the manufacturer of the inverter.

Lethal arc flashes may be generated when disconnecting a power conduit, such as when
disconnecting an inverter from the DC power supply while still bearing a current:

Never disconnect the solar generator from the inverter while still connected to the mains.

NORMS AND GUIDELINES

All norms and guidelines presented here are published and intended for use in Germany. The
guidelines provided in each respective edition must be complied with. Please note that ins-
tallations outside Germany will also be subject to additional national norms and guidelines.

HOW TO INSTALL THE FRAMEWORK

All roof area installations must be carried out in accordance with currently valid technical
building standards, particularly those specified in the DIN norms and the requirements for-
mulated in the ‘German Roofers’ Rulebook’.

Check to ensure all screwed attachments are correctly tightened.

Adhere to the suggested torque values.

Regardless of the testability of the statics, prior to every installation it is essential to
ensure the product complies with DIN EN 1991 statics requirements on site.

DIN Norm EN 1991 ‘Forces Affecting Load-Bearing Structures’ – and all accompanying
national application documents.

Part 1-1: Weight, weight distribution, counterweighting and payloads in above-

ground construction

Part 1-3: Snow loads

Part 1-4: Wind loads

DIN Norm EN 1990: ‘The Fundaments of Support Structure Planning’ – and all accom-

panying national application documents.

The structure on which the system is mounted is evaluated for compliance under DIN

EN 1993 ‘Measurement and Construction of Steel Structures’, and DIN EN 1999 ‘Mea
surement and Construction of Aluminium Support Structures’.

Ensure suitability of the substructure for load-bearing purposes, like dimensions,

current conditions, relevant material properties, general load-bearing structures – and
of all individual layers affected such as layers of insulation.

Ensure the flow and drainage of rainwater is not obstructed.

Always take the physical effects on building work into account, such as the risk of dew

penetrating layers of insulation.
