NOTE
In accordance with IEC 61730 Class A, connected PV modules must be dimensioned for the DC system
voltage provided, and at least for the value of the AC grid voltage.

Connecting the PV generator

The PV generator is connected on the right in the connection area (see Figure 18 and Figure 19 on page 18).
Risk of fatal injury due to contact voltages!
Under the action of light, solar modules can generate lethal voltages that cannot be discon-
nected.

CAUTION
Damage to the device in case of faulty configuration of the DC connector.
A faulty configuration of the DC connector (polarity +/-) causes equipment damages in the DC
connection if it is connected permanently.
Connecting the PV generator (S, M version)
PV generator is dimensioned according to the performance character-
istics of the unit.
1. Unscrew the cable fittings.
2. Remove the outer cladding of the DC cables.
3. Insert the DC cables through the cable fittings into the connection area
(see Figure 18 on page 18).
4. Strip the insulation from the DC cables.
5. Fit the DC cables with a ring cable lug.
6. Remove the protection against contact from the PV+ and PV- terminal.
7. Screw the cable ends onto the DC connections (PV+/PV-) according
to the polarity of the PV generator (tightening torque - see Table 5 on
page 19).
8. Check secure fit of all connected cables.
9. Remove the protection against contact from the PV+ and PV- terminal.
10. Tighten the cable fittings.
» The inverter is connected to the PV generator.

DANGER
During installation: Electrically disconnect the DC positive and DC negative from the protective
earth (PE).
The DC connection may only be made while power is switched off. Cover solar modules if necessary.
Only touch the PV generator cables on the insulation. Do not touch the exposed ends of the cables.
Avoid short circuits.
Please check polarity (+/-) of the DC connector before connecting the DC generator
Before using the solar modules, check the vendor's calculated voltage values against those actu-
ally measured. The DC voltage of the PV system must not exceed 1100V at any time.
