PV generator connection
· Preparation
Execute the DC cabling according to your
electrician's system dimensioning. Check
each PV string for correct functioning
by performing a no-load voltage current
and short-circuit current measurement.
To achieve the necessary protection
against hazardous contact voltage during
the installation of PV systems, the positi-
ve and negative conductors must be kept
separate from the ground potential (PE).
Contactable, conductive parts of the PV
generator (e.g. metal frame, supporting
structure etc.) must be earthed (connec-
ted to PE).
Check that the generator is free from
ground faults.
Make the electrical connection to the
solar inverter.

· Connection
The PV generator is connected via the
externally accessible, shock-proof TYCO
SOLARLOK connectors, which are enclosed
with the delivery. The TYCO SOLARLOK
connectors are designed for a cable cross-
section of 4 mm2 and must be crimped
(see data sheet and connector assembly
with TYCO crimping tool on page 144).
Connect the two right DC female connectors
with «+», the two left DC female connectors
with «-» of the PV generator (see figure
below).
