ABQ2026IQE01_A - Installation and Operation Manual
8.2. Connection area
The metal parts of the inverter (equipment ground) are electrically connected to the grounding bar on the front of
the DCAC connections module. All ground connections must be done here.
8.3. Wiring requirements for the ground connection
•
The correct dimensioning of the grounding conductor is the installer’s responsibility, depending on the
plant specifications and inverter characteristics. The recommended minimum cable size is 16 mm
2
.
•
Copper and aluminum cables must be used, dimensioned based on inverter and PV plant characteristics.
•
The selected breaking capacity on the AC thermomagnetic circuit breaker AC is 65 kA.
•
Ingeteam accepts no responsibility for the installation of the inverter in installations with a higher than
specified short-circuit current.
•
The short-circuit current delivered by the inverter is considerably lower than the breaking capacity of the
AC thermomagnetic circuit breaker.
8.4. Ground connection via a terminal
8.4.1. Requirements for the ground connection via a terminal
•
For the ground connection, the terminals must be compression terminals.
•
Only use the bolts and washers provided by Ingeteam upon delivery of the unit.
•
Use copper or tinned copper terminals.
•
The torque should be 50 Nm.
