Manual
7.6.3 Connecting the PV generator
DANGER
Risk of fatal injury due to electric shock!
Severe injuries or death will result if the live connections are touched. When there is solar radiation on the PV
generator, DC voltage will be present at the open ends of the DC cables.
1. Activate the connection power at the switchbox or string combiner with the DC isolator switch.
2. The DC connection is intended exclusively for PV generators. Other sources fall within the scope of im-
proper operation (e.g. batteries).
3. Only touch the PV generator cables on the insulation. Do not touch the exposed ends of the cables.
4. Avoid short circuits.
5. Do not connect any strings with a ground fault to the device.
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
NOTE
Use of suitable cable lug sizes
Devices with DC switch have a limited connection space ( [See section 7.3} Page 24]) The maximum cable lug
length of 3,78 In extends into the cable gland to ensure proper function and use [See figure 27 [} Page 30].
1. For the UL market, a larger connection space is required by standard. For this purpose, the DC input plate
must be replaced by an external bending box (see chapter Accessories under Technical data).
