Units without a transformer (TL)
To avoid arcing, once the wires are connecting to the strips, check the safety clearances between live parts on each
strip or any other metal point on the unit. We recommend a clearance of 20 mm.
After working on the terminals the polycarbonate guard must be put back into place.
5.4.13. Connecting to the PV array
The cables for connecting the unit to the PV array enter through the conical glands in the base.
Before any handling, check that there is no electrical hazard in the voltage input from the PV array.
Never forget that whenever they receive solar radiation, the panels’ terminals generate voltage.
The inverter can therefore have voltages of up to 1000 volts inside even when not connected to the
grid.
When checking that there is no voltage, wearing dielectric gloves and safety goggles approved for
electrical hazards is required.
CAUTION
Connect the positive pole of the panel series to the terminals marked , and the negative pole to the
terminals marked .
If the distance between the inverter and the PV array connection point requires the use of longer cables, an external
distribution box must be used close to the inverter to make this connection.
The equipment has two copper strips with 2 13 mm diameter orifices for entering M12 size ring-terminated cables.
The maximum gauge recommended by Ingeteam for these wires is 4 times 240 mm². In each hole a cable can be
connected from each side of the plate. So up to four cables can be connected to each strip.
To avoid arcing, once the wires are connecting to the strips, check the safety clearances between live parts on each
strip or any other metal point on the unit. We recommend a clearance of 20 mm, with a minimum 10 mm.
To access these terminals the protective polycarbonate sheet must be removed.
