5.3.7. Connection to the PV array
The connection of the inverter to the PV array is made through a hole and are connected to a screw terminal dock.
Never forget that, whenever panels are exposed to solar radiation, voltage is generated at the terminals.
Therefore, the inverter interior may hold voltages of up to 550 volts even when not connected to the Grid.
The inverter has a maximum system voltage of 550 Vdc. Check that the PV array configuration will never be capable
of supplying this voltage to the inverter, not even in the most adverse situations such as at an ambient temperature
of 14 ºF (-10 ºC).
Ingeteam Inc will accept no liability for any damage caused by a DC voltage of more than 550 Vdc.
CAUTION
Connect the positive pole of the string of panels to the terminals marked "+" and the negative pole
to the terminals marked "-".
The inverter factory-supplied terminals can withstand a maximum current of 20 amps.
5.4. Electrical disconnection
To disconnect the inverter, follow the steps indicated in section "5.3. Electrical connection" hereof, but in reverse
order.
Pay particular heed to the following warning notice:
CAUTION
The inverter contains electric capacitors which can maintain high voltages even after disconnection
from the panels and grid.
And remember:
CAUTION
The Ingecon
During the equipment installation and maintenance operations, it is mandatory to use personal protective equipment
(PPE): safety helmet, gloves and footwear.
CAUTION
Do not touch the inverter sides and rear, which can reach high temperatures.
Any installation work requiring the unit to be opened must be performed in a dry atmosphere, to prevent the ingress
of moisture that could condense and damage the electronics.
Ingeteam Inc assumes no liability for damages caused by the improper use of its equipment.
5.5. Disassembling
To disassemble the inverter, follow the steps indicated in section "5.2. Wall mounting the equipment" hereof, but in
reverse order.
