28 Installation Instructions
4. Connect the other end of RS485 cable to crystal connector by repeating the
procedure 3 and 4.
5. The inverter can connect with a PMU by a RS485 cable at both ends with a
crystal connector. After the PMU connects with PC by Ethernet or USB, the
inverter can communicate with PC.
Notes:
The wires connection sequence of two ends of a RS485 cable is
the same.
5.6 Safety protection
5.6.1 Grid voltage and frequency protection
Eversol inverters monitor the voltage and frequency level of the grid. If the level is
outside the range permitted by state grid standard, the inverter stops feeding and restarts
only when the grid voltage and frequency return to normal.
5.6.2 Over temperature monitoring
