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

97 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).
