APPENDIX Ⅸ SYSTEM POWER ON AND SHUTDOWN

POWER ON STEPS

These power on steps are applicable to SVG when it is at off-position. Operation steps are as follows:
Supply power to SVG by closing the breaker between the grid and SVG.
I.
Close the breaker in the cabinet. The HMI starts to work. If the green running indicator light of main
II.
cabinet flicks, it will indicate that SVG is normally energised. In case of any failure, the red alarm
indicator on the cabinet will be on.
When powered on and normal supply is established and if SVG has been set as 'Automatic power on'

mode, the system SVG will power on automatically.
If it is set as 'manual power on' and after the monitoring screen has started upon the energising process,
IV.
click 'power on' in the menu. After a normal soft power on, the system will switch on the power module.

POWER OFF STEPS

Click power off in the menu to stop system immediately and enter the 'stop' state.
Note: In a stop state, the internal system and terminal are still electrified (live). When the power is not
disconnected, any maintenance or opening the cabinet is strictly prohibited.

AUTO POWER ON

In case of abnormal grid voltage or frequency, SVG will automatically stop compensating current output and
enter standby state (standby mode will note operate in case of power outage).
When the following conditions are met, SVG will automatically re-run and recover output.
The utility power has recover to normal
I.
Auto-power on has been enabled in Settings-General-Start mode;
II.
Auto-power on delay is enabled (default: 10 sec)
III.
Note: If the auto power-on feature of SVG isn't enabled, the user needs to manually start SVG using the
touch/monitor screen.

EMERGENCY STOP

In the case of an abnormal function or output of SVG, press the EPO button on the front panel to turn off the
module (for cabinet solution). Immediately disconnect the circuit breaker or isolation switch between SVG and
the grid to cut off the system input power.
After pressing EPO and finishing troubleshooting, if all tests appear OK, re-press the EPO button and click on
the monitor screen, select 'Clear fault', and perform the startup operations if there is no alarm sounding.
WARNING
Only after SVG is installed and commissioned by an engineer correctly
and the external power switch has been closed, can the power on steps
be executed.
WARNING
To prevent personal injury and in case of cabinet maintenance or
opening after shutdown, disconnect all input switches. Conduct
relevant measurements using a multimeter to ensure personal safety.
