4.1 Wiring 

DO NOT do any change or adjustment on the cable of Junction Box.   
DO NOT disconnect cable by yourself!

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.

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.
