10�1 Notes on wiring the connections
The wiring of the inverters and accessories needs to be carried out with the greatest care and attention.
The most frequent source of errors when installing the Solar-Log™ is faulty wiring.
For this reason, we recommend:
•
Wiring with high quality cables
For example: LIYCY >=0.14mm or Cat 5/7 SSTP
•
Refer to the manufacturer's specifications in regard to UV resistance and mounting type when
wiring in outside areas.
•
A larger cable diameter is recommended for longer distances.
•
Use ferrules with flexible wires
•
Twist the corresponding wire pairs and shielding
•
Wire from left-to-right.
•
Wire from light to dark.
