5.4.10. Ground connections
The metal parts of the inverter (equipment ground) are electrically connected to the grounding bar on the front of the cabinet.
To ensure the safety of personnel, this terminal must be connected to the installation’s ground.

5.4.11. Connecting the auxiliary supply
In the case of Ingecon
®
Sun Power TL, the fans, contactors and auxiliary supplies for the electronics require an auxil-
iary supply in order to operate.
This power must be provided at the two-terminal terminal strip installed for this purpose and should be 230 V
50/60 Hz. Power required will be less than 1000 VA.
In these units, the auxiliary input is on the lower right of the cabinet.
5.4.12. Grid connection
The cables for connecting the unit to the grid enter through the glands at the base of the cabinet. They must withstand
at least the phase voltage and 1000 V between a phase and ground.
If the inverter and the grid connection point are far enough apart to require the use of longer cables, an external
distribution box must be used close to the investor to make this connection.
The cable gauge must be suitable in each case for the power rating of the unit and site conditions.
Protections for the connection of inverters to the electrical grid can withstand a short-circuit current of up to 70 kA.
