10 Connector Assignments and Wiring
The following connecting cables, which may be needed for various purposes, are not included in the
package content.
•
To connect a router, you need a network cable with the appropriate length. If you want to connect
the Solar-Log™ directly to your PC or laptop, you need to use a crossover cable.
•
Cable to connect the Solar-Log™ to an inverter.
•
Sets of prefabricated cables are available as accessories suitable for the inverter concerned. The
length of these cable sets is 3 m.
•
If you want to connect several inverters to Solar-Log™, you need suitable cables and connectors to
connect the inverters to each other.
•
For each connection to the Solar-Log™ (RS485 - A and RS485/422 - B or - C) a separate cable
must be used.
•
When wiring with CAT cables, the twisted pair of wires should be used.
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
2
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.
