4.1 Wiring

DO NOT do any change or adjustment on the cable of Junction Box.
DO NOT disconnect cable by yourself!
IMPORTANT IMPORTANT
IMPORTANT IMPORTANT
The cable must not be bent or crushed on the direct exit of the cable screw joint. A minimum
bending radius r≥4x (static steady), r≥5x (dynamic) cable diameter must be maintained. The
cable must be routed in a way that tensile stress on the conductor or connection(s) is
prevented.
Pay attention to the following when wiring:
1. 1. 1. 1. Correct wiring scheme Correct wiring scheme
Correct wiring scheme Correct wiring scheme
Check that the wiring is correct before commissioning the system. If the measured open
circuit voltage differs from the specifications, then there is a wiring fault. Ensure that the
polarity is correct.
2. 2. 2. 2. Correct DC plug connec Correct DC plug connec Correct DC plug connec Correct DC plug connection method
Make connections only in dry conditions. Ensure that connections are secure and tight.
3. 3. 3. 3. Use correctly rated materials Use correctly rated materials Use correctly rated materials Use correctly rated materials
Use PV rated solar cable for wiring and suitable connectors only. Ensure that they are in
perfect electrical and mechanical condition. Use only single wire cables. Select a suitable
conductor diameter to minimize voltage drop.
