Installation manual
The PV array is grounded via a thermomagnetic circuit breaker connecting one pole of the PV array, negative or
positive, to ground. The polarity of the connection depends on the type of panel technology.
This kit may only be installed in units with a transformer or TL units without a transformer connected to just one transformer.

Q10
The thermomagnetic circuit breaker protection will open the PV array connection to ground when an insulation fault in
the PV array generates a current through the connection which is greater than the protection's release current.
The current generated by the panels is closed by the lack of a positive pole, closing via the negative pole connection,
until it returns to the panel. When the current exceeds the thermal value of the protection (10 A), the circuit is opened
and current ceases to flow to ground.
