Check that all wires are connected and secured before proceeding to the converter start-
up.
If these steps are validated the converter is ready to be started.
4.5.1. Start-up
Switch on the thermal-magnetic circuit breaker of the grid side of the converter. After switching
it on, the converter will initiate the start-up sequence. This sequence will activate the cabinet
fans for one second.
At this point the converter will start the initialization process, as described previously. During
this time the embedded PC will load the operating system and the communications program.
The converter will ignore any command during this process.
The Initialization state can last up to 15 seconds. If every step is completed successfully the
converter will move automatically to Standby state.
Summarizing, to put the equipment in Run state the user should follow step by step the next
checklist:
1. Connect the mains.
2. Turn on the thermal-magnetic circuit breaker.
3. Activate the cabinet output by switching the disconnector.
4. Deactivate the emergency stop (pull out the button). (Initialization
Standby).
5. Send the Enable signal. (Standby
Precharge
Ready).
6. Select the connection mode between Independent or Parallel phases. This option
cannot be done while the converter is running.
7. Select the operation mode. Please keep in mind that not all EUTs are compatible with
all operation modes. For example, if the converter is acting like a current source, do not
connect any other current sources at the output. The connection mode cannot be
changed during Run operation.
8. Send the Run signal. (Ready
Run).
Please keep in mind that not all EUTs are compatible with all operation modes. If
the converter is operated as a current source, please do not connect any other
current sources at the output.
4.5.2. Stop
Once the equipment is running (Run state) it may be stopped in three ways:
4.5.2.1. Full stop
This type of stop is recommended if the electrical connections are to be modified or the
converter will be stopped for a long time.
When the converter is running, special care must be taken. It is strongly recommended to follow
the next steps:
