Note 2
: The cavity formed after the conductor has been crimped must completely wrap the conductor wires.
The core of the wire must be in close contact with the terminal.
Figure 20 – Preparing the ground cable (2)
3)
Install the crimped OT terminal and flat washer using the M6 screw in the hole located on the
inverter heatsink, as shown in the figure; tighten the screw to a torque of 5 Nm using an Allen key.
Note
:
To ensure the anti-corrosion performances of the ground terminals, apply silica gel on them after
connecting the ground cable.
4.3.
Connecting the DC input power cables
Connect the 3PH 50000TL-60000TL-V1 inverter to the photovoltaic strings using the DC input power cables.
Select the input mode: the 3PH 50000TL-60000TL-V1 inverter has three MPPTs, which can function either
independently or in parallel, depending on how the system was designed. The user can choose the
appropriate MPPT operating mode.
Independent mode (default):
If the strings are independent (e.g. installed on three separate flaps), the input model must be set to
“independent mode.”
The setting method is described in relative section.
Parallel mode:
If the strings are connected in parallel, the input mode must be set to “parallel mode.”
The setting method is described in relative section.
Note
Depending on the type of inverter, select the appropriate accessories (cables, fuse holder, fuse, switch, etc.).
The open-circuit voltage of the photovoltaic system must be lower than the maximum allowable DC input
voltage of the inverter.
