Connecting the output cables
– Guide the cables through the cable entries and into the housing.
– Connect the conductors to terminals L+ and L-.
When doing so, refer to the figure and table below.
Figure 5-5 -X4: Terminals L+ and L- for output cables
Connecting the PV strings
– Guide the cables through the cable entries and into the housing.
– Connect the conductors to the corresponding terminals.
When doing so, refer to the following figures and tables.
Use copper or aluminum cables to connect the outlets.
Note the following when using aluminum conductors:
When connecting aluminum conductors, a non-conductive oxide film forms when the con-
ductors are stripped. Aluminum conductors are only suitable for installation locations that
are free from humidity or aggressive atmospheres where possible.
– Separate the stripped end of the aluminum conductor from the oxide film using a
blade and immediately dip it in non-acid and non-alkali Vaseline.
– When connecting aluminum conductors, the screws must be tightened with the max-
imum permissible tightening torque (see table “Connection terminal blocks” on
page 17).
