Powering On The System - Huawei SmartACU2000B Quick Manual

8

Put on insulation gloves before powering on the system.

Ensure that the power voltage of the smart array controller is within the operating voltage range,

and the three-phase input voltage is within the PLC module operating voltage range.

1. Turn on the single-phase power switch that controls the power supply from the remote box-type

transformer to the smart array controller.

2. Turn on the three-phase power switch that controls the power supply from the remote box-type

transformer to the smart array controller.

If the smart array controller supports the access of one PLC route, turn on one three-phase



power switch.

If the smart array controller supports the access of two PLC routes, turn on two three-phase



power switches.

3. Check that the input voltages of all switches of the smart array controller are within appropriate

operating voltage ranges using a multimeter.

4. Turn on the QF01 single-phase input switch on the smart array controller.

5. Turn on the DC input and output switches on the smart array controller.

If 24 V DC input and output are not used, skip this step.



If 24 V DC input is used, turn on the QF07 DC input switch.





If 24 V DC output is used, turn on the QF06 DC output switch.

6. Turn on the three-phase input switch on the smart array controller.

If the smart array controller supports the access of one PLC route, turn on the QF02 (or FU01)



three-phase input switch.

If the smart array controller supports the access of two PLC routes, turn on the QF02 and



QF04 three-phase input switches.

For details about the status of the energized SmartLogger2000 and PLC CCO as well as the



commissioning procedure, see the SmartLogger2000 User Manual. When the smart array

controller communicates with the inverter over PLC, log in to the embedded WebUI of the

SmartLogger2000, choose Monitoring > PLC > Networking Settings, and set Networking to

Enable (default value). When the smart array controller communicates with the inverter only

over RS485, set Networking to Disable. (The WebUI screenshots for SmartLogger

V200R001C30SPC106 are used as an example.)

The LAN switch can be directly put into use without commissioning after power-on.
