5.3.4 Multipurpose inlets
Some PV installations require the inverter to be connected to auxiliary equipment, such as solar radiation sensors,
heat sensors, etc.
The orifices provided for this function can be opened by breaking the knock-out in the unit's base. Once the orifices
have been opened, they must be fitted with M12 and/or M20 metric cable glands which accept pipes of a diameter
between 3.5 and 7 mm for PG 12 and between 7 and 13 mm for PG20.
Once the connection has been made, check that the cable glands used have been "closed" appropriately to guar-
antee sealing of the box.
A closure which is not sealed may allow moisture to enter and seriously damage the unit, invalidating the manufac-
turer's warranty in addition.
If a knock-out which is not to be used is opened accidentally or one which has been fitted with a cable gland is no
longer used, these open orifices must be closed with a sealing plug which maintains the unit's hermetic seal.
See the Section «Hermetic closure of the unit».
5.3.5 Connection for communication over RS485 serial line
All INGECON
SUN LITE units have communication over an RS485 serial line. As the RS485 communication
board is already wired to the Harting HAN
4A female connector, simply plug in a male connector of the same type.
Refer to "AAX2002IKH01 Installation Guide for Communications Devices" for how to wire correctly the male con-
nectors 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 "AAX2002IKH01 Installation Guide for Communications Devices".
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.
