Connecting The Pv Generator - Kaco blueplanet 50.0TL3 Betriebsanleitung

Operating Instruction I
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).

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. Only touch the PV generator cables on the insulation. Do not touch the exposed ends of the cables.
2. Avoid short circuits.
3. Do not connect any strings with a ground fault to the device.
CAUTION
Damage to the PV generator in case of faulty configuration of the DC connector.
A faulty configuration of the DC connector (polarity +/-) causes equipment damage in the DC connection if it is connected
permanently.
1. Please check polarity (+/-) of the DC connector before connecting the DC generator.
2. Before using the solar modules, check the vendor's calculated voltage values against those actually measured. The DC
voltage of the PV system must not exceed the maximum no-load voltage at any time.
Connecting the PV generator
↻ PV generator is dimensioned according to the performance characteristics of
the unit.
1. Loosen the cable fittings [ W_36(M32 )].
2. Remove the outer cladding of the DC cables.
3. Pass the DC cables through the cable fittings into the connection compartment
[Ø 15 - 21 (M32) mm ].
4. Strip the insulation from the DC cables.
5. Fit DC lines with an ring cable lug [max. width b 20 mm].
6. Remove the protection against contact from the PV+ and PV- terminal.
7. Screw the cable ends of the PV generator onto the DC connection according to
the polarity of the battery [ T_TX35 /
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 [ W_36 /
ð The device is connected to the PV generator.
