Be sure to maintain the time intervals as
specified by the inverter manufacturer between
switching off the inverter and beginning any
further work.
Danger! Risk of fatal injury due to electric

(no DC current flow).
4.
Disconnect plugs by the use of appropriate
and qualified tools of the manufacturer.
5.
When connecting the modules proceed in
reverse order.
Danger! Risk of fatal injury due to electric

Ä
Electrical work may only be performed by
qualified and skilled personnel (see page 3).
Ä
Ensure correct polarity.
Ä
Use solar cables for the connection at the
junction box outlet.
Ä
Only interconnect connectors of the same type and
manufacturer.
Ä
Use minimum 4 mm
2
copper wires insulated for
a minimum of 90 °C for field connections.
Note! Module damage may occur!
Ä
Ensure that the cabling is not under mechanical
stress (Comply with bending radius of ≥ 60 mm).
Ä
Ensure that the cables do not run between module
and mounting rail or structure (danger of pinch).
Ä
Do not connect modules with different
orientations or angles of inclination in the same
string.
Ä
Ensure for a tight connection between the
plugs. Plugs click together audibly.

Ensure that all electrical components are in a
proper, dry, and safe condition.
Ä
To avoid complex cabling arrangements, it is
often advantageous to rotate some modules
180°.
Ä
Module orientation can clearly be identified
from the front side by the serial number and
barcode labelled behind the module glass on
the side with negative connection cable.
