Electric connections: safety procedure
Before carrying out any kind of operation inside the inverter, always place the equipment in safety conditions.
To do this follow the instructions provided below:
•
Make sure that the inverter is NOT running.
•
Press the emergency stop button on the front door.
•
Disconnect the cabinet’s auxiliary power supply.
•
Wait at least 10 minutes before opening the doors.
•
Turn off any disconnector switches up- and downstream from the inverter.
WARNING
Before carrying out any operations inside the electrical cabinet make sure it is in safety
conditions by turning it off and opening the DC side and AC side switches.
DANGER
The SUNWAY TG TE is powered by two completely separate voltage generators: the grid
and the PV field. Make sure that both generators are disconnected before carrying out
any kind of work inside the inverter.
DANGER
Turning off the switches on the PV field side and the grid side inhibits operation of the
SUNWAY TG TE but hazardous stored residual energy may persist on the AC grid and PV
field connection terminals (X2 and X2B terminal boards), on the fuse holders and on the
conductors and components upstream from the DC disconnector and the AC circuit
breakers (please refer to the Electrical and Mechanical Diagram).
DANGER
After turning off the inverter wait at least 10 minutes before opening the cabinet doors to
give the DC-link capacitors time to discharge.
