7.6.3 Designing the PV generator

CAUTION
Damage to components due to faulty configuration
In the expected temperature range of the PV generator, the values for the no-load-voltage and the short
circuit current must never exceed the values for U
› Observe limit values in accordance with the technical data.
NOTE
Type and configuration of the PV modules.
Connected PV modules must be dimensioned for the DC system voltage in accordance with IEC 61730 Class
A, but at least for the value of the AC grid voltage

7.6.4 Connecting the PV generator

DANGER
Risk of fatal injury due to electric shock!
Severe injury or death will result if the live connections are touched. When there is sunlight present on the
PV generator, there is DC voltage on the open ends of the DC cables.
› Only touch the PV generator cables on the insulation. Do not touch the exposed ends of the cables.
› Avoid short circuits.
› Do not connect any strings with a ground fault to the device.
Connecting the PV generator
↻ PV generator is dimensioned according to the performance characteristics of the unit.
1 Undo the cable fittings [ W_46].
2 Remove the outer cladding of the DC cables.
3 Pass the DC cables through the cable fittings into the connection compartment.
4 Strip the insulation from the DC cables.
5 Screw the cable ends of the PV generator onto the DC connection according to the polarity of the battery [ T_TX35 /
]
6 Check secure fit of all connected cables.
7 Remove the protection against contact from the PV+ and PV- terminal.
8 Tighten cable fittings [ W_46 /
» The device is connected to the PV generator.
7.7

Sealing the connection area

1 The requirements of protection class IP65 are met by closing the unused cable fittings with blind caps.
2 Close the housing door and lock it with a control cabinet key.
» The device has been mounted and installed.
