Designing The Pv Generator; Connecting The Pv Generator - Kaco blueplanet 87.0 TL3 Betriebsanleitung

Operating Instruction I
5. Measure the electrical resistance between the protective earth (PE) and the negative cable of the PV generator.
ð In addition, ensure that the PV generator has a total insulation resistance of more than 2.0 MOhm, since the
device will not feed in if the insulation resistance is too low.
6. Rectify any faults before connecting the DC generator.
6.6.2

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
1. 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
NOTE
Sizing of the PV generator
The device is designed with a reserve of DC short-circuit current withstand capability. This allows oversizing of
the connected PV generator. The absolute limit for the PV generator is the value of the maximum short circuit
current (lsc max) and maximum open circuit voltage (Uoc max).
6.6.3

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.
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.
