longer used, these open orifices must be closed with a sealing plug which maintains the unit’s hermetic seal.
5.3.5. Connection for communication via RS-485 serial port
All Ingecon
®
μWind units have communication facilities over an RS-485 serial line. As the RS-485 communication
board is already wired to the Harting HAN
®
4 A female connector, simply plug in a male connector of the same type.
Refer to “AAX2002IKI01 Installation Guide for Communications Devices” for how to wire correctly the male connec-
tors which need to be plugged into the connector on the inverter.
This connector can be supplied by Ingeteam if requested together with the unit.
5.3.6. Connection for communication by other means
At the request of the installer, inverters may optionally incorporate hardware for communicating via:
•
GSM/GPRS telephone
•
Ethernet
In all these units, the auxiliary signals connect directly to the corresponding communications card.
See the Communications Accessories Manual “AAX2002IKI01”.
5.3.7. Connection to ground and to the electricity grid
The inverter’s metal parts (unit ground) are electrically connected to the ground pin in the grid connection quick
connector.
To ensure the safety of personnel, this terminal must be connected to the installation’s ground.
The connection of the grid Neutral and Phase to the inverter is made by means of a three-terminal connector.
The maximum diameter of the cable pipe permissible for the connector is 14 mm.
If the inverter and the grid connection point are far enough apart to require the use of cables of a greater section, an
external junction box close to the inverter to make this section change is recommended.
Protection of the connection to the electricity grid
It is necessary to install protection elements in the connection between the inverter and the electricity grid.
Thermomagnetic circuit breaker
A thermomagnetic circuit breaker and/or fuse must be installed in the connection from the inverter to the electricity
grid.
The following table provides the necessary data for the selection of these devices by the installer. All data in Amperes.

When selecting the protection in an installation, it must be borne in mind that its circuit breaking capacity needs to
be higher than the grid connection point’s short-circuit current.
It must be taken into account for correct selection of the protection that the ambient working temperature influences
the maximum current permitted by these protections as indicated by the manufacturer.
