The grid side of the power supply is protected by a thermal-magnetic circuit breaker.
Be sure that this breaker is switched off:
Check that all wires are connected and secured before proceeding to the power supply
start-up.
If these steps are validated the power supply is ready to be started.
4.5.1.
Start-up
Switch on the thermal-magnetic circuit breaker of the grid side of the power supply. After
switching it on, the power supply will initiate the start-up sequence. This sequence will activate
the cabinet fans for one second and, if an internal isolation transformer is used, an internal
relay for the transformer precharge will also be activated.
At this point the power supply will start the initialization process, as described before. During
this time the embedded PC will load the operating system and the communications program.
The isolation detector will also perform a self-test before being operative. The power supply
will ignore any command during this process.
The Initialization state can last up to 15 seconds. If every step is completed successfully the
power supply 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 input thermal-magnetic circuit breaker.
3.
Activate the cabinet output by switching the disconnector.
4.
Deactivate the emergency stop (pull out the button). (

6.
Select the connection mode between independent or parallel. This option cannot be
undone while the power supply is running.
7.
Select the operation mode. Please keep in mind that not all loads are compatible with
all operation modes. For example, if the power supply is acting like a voltage source,
do not connect any other voltage sources at the output.
