Installation and operating instructions V00 49
7.2 Mechanical checks
Carry out the main mechanical checks to ensure the IP protection level of the
inverter:
1.
Ensure that the lower cover has been securely screwed in place.
2.
Use sealing caps for tight sealing of unused DC input connectors.
3.
Make sure the RS485/RS422 connection has been connected securely.
4.
Ensure that the cable glands have been securely screwed in place.
7.3 Start-Up
After finishing the electrical and mechanical checks, switch on the AC circuit breaker
and DC-switch in turn. The inverter will start up automatically. Usually there are
three statuses during operation:
Waiting: When the initial voltage of the strings is greater than the minimum DC input
voltage but lower than the start-up DC input voltage, the inverter is waiting for
sufficient DC input voltage and cannot feed power into the grid.
Checking: When the initial voltage of the strings exceeds the start-up DC input
voltage, the inverter will check feeding conditions at once. If there is anything wrong
during checking, the inverter will switch to the “Fault” mode.
Normal: After checking, the inverter will switch to “Normal” state and feed power
into the grid.
During periods of little or no sunlight, the inverter may continuously start up and
shut down. This is due to insufficient power or input voltage generated by the PV
array. If this fault occurs often, please call service.
Quick Troubleshooting!
If the inverter is in "Fault" mode, refer to Section 11 "Troubleshooting" in
the manual.
