Luxor eco line 60/225-235W, Installation Instructions Manual

equivalent plug connections for the wiring. 

Only use special, UV-resistant solar cables and suit-

able connectors. Do not bend the cables and observe 

the minimum bending radius. Please make sure that 

the cables are laid such that they cannot rub against 

sharp-edged objects or 

roof tiles. UV-resistant cable ties, for example, are 

suitable for fastening.  Some mounting systems also 

have special cable fastenings and guides. Make sure 

the the cables are not installed under tensile stress. 

Replace damaged cables.

If possible, ensure short cable lengths to minimise 

intrinsic losses.

Please check the open circuit voltage and the short 

circuit current for each installed strand (see also 

section 4.4).

4.4 tEst

Test all electric and electronic components of the sys-

tem before use. Follow the instructions in the manuals 

provided with the components and equipment. 

Perform a test of the open circuit voltage and short 

circuit current before connection of the system.

opEn CirCuit VoltagE

Check the open circuit voltage of each strand with a 

digital multimeter. The measured values should corre-

spond with the total of the open circuit voltage for the 

individual modules. You will find the nominal voltage in 

the datasheet of the module used*. If the measured 

value is substantially lower than the expected value, 

continue in accordance with the section "Trouble-

shooting at low voltage".

short CirCuit CurrEnt

Test the short circuit current of each series circuit. 

This can be measured directly with a digital multim-

eter, which is connected to two clamping plates of the 

series circuit or module, or with any load, such as e. g. 

PV lighting, in order to carry out a rough measure-

ment. Please make sure that the nominal scale of the 

ampere meter or the rated current of the load must 

amount to 1.25 times the rated short circuit current 

of the series module. You will find the rated current 

in the datasheet of the module used. The measured 

value can vary strongly depending on the weather, 

time of day and possibly the shade.

*  The electrical values of the provided individual measurements al-

located to the respective serial number are decisive.
