Requirements specified by the power supply utility
When operating the photovoltaic unit as
a grid feed system, observe all current
requirements and regulations of your
local power supply utility.
The photovoltaic system must be suita-
ble for operation with the power grid of
your local power supply utility, and any
interference affecting the grid or third
parties must be reliably prevented.
Only approved contractors may connect
the system to the power grid and install
the earthing/surge protection. Agree all
necessary steps in connection with the
supply meter with the relevant power
supply utility.
The photovoltaic system must be accep-
ted by an electrical contractor who will be
responsible to the user and the power
supply utility for its correct installation.

In step 2, do not tighten the nuts until after step 3.
Note
Secure the centre clamps between the
last module and the one before it after
the last module has been positioned,
enabling that module to be pushed under
the end clamp.

Installation with mounting brackets
For example, installation on sheet steel
roofs.
Use on-site fixings to secure the brack-
ets (e.g. standing seams).
