Fault 514: communication error between the meter and the
Fault 514 indicates that there is a communication error between the meter and the inverter.
1 Summary
It is best to call us as soon as possible when any fault is
1.
Is there another inverter on the same phase as the SH5K? If so, go to section 2 (click the number). If the other inverter is
the SH5K+, then check the wiring diagram in section 7 (again, click the number—all section numbers in this document
are links).
2.
Check section 3 to check the communication cable wiring.
3.
Is it a single-phase or three-phase property? Check the appropriate wiring diagrams in sections 4 and 5, respectively.
4.
Is there a long meter communication cable run, i.e. is the inverter far from the main switchboard and the meter? Put the
120 Ohm resistor switch 2 on as per section 6.
5.
Restart after correcting the wiring as per section 8.
6.
To check the installation and wiring is correct, check the power flows on the LCD.
7.
Replace the communication cable as discussed in section 11.
8.
Refer to section 11 for examples of how not to install the meter.
