In these units, the auxiliary input is on the cubicle of the first inverter. In all multi-inverter units, the auxiliary connec-
tion is under the inverter no. 1 between the AC feed and the electromagnetic interference filter.
Location of grounding bars
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 dis-
tribution 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 inverters to the electrical grid (all versions which include them) can withstand a short-circuit cur-
rent of up to 70 kA. NAC models do not have this protection. It must be assembled outside the unit and coordinated
with the installation.
Before any handling, check that there is no electrical hazard in the voltage input from the grid.
When checking that there is no voltage, wearing dielectric gloves and safety goggles approved for
electrical hazards is required.
The autonomous three-phase outputs with no neutral of these units is as follows:

Sun Power Max units with AC cabinet have as many autonomous three-phase, non-grounded outputs with no
neutral as electronics blocks, i.e., 1, 2, 3 or 4. They should be connected using an IT scheme. Each three-phase feed
comprises three 275 V or 220 V bimetallic terminals, depending on the model, and up to 368 A. These comprise an
M16 stud ring terminal for cable up to 300 mm2 or double cable up to 240 mm2. They are in the far right cubicle.
