Consult section "Important safety instructions" and the following instructions before working on the unit.

9.1. Safety instructions for the DC connection

DANGER
Make sure there is no voltage present on the unit before starting the connection.
Do not switch on the power to the unit until you have successfully made the rest of the connections and the unit is
closed.
Use the Personal Protective Equipment specified in the section "Personal Protective Equipment (PPE)".
While connecting the inverter, make sure of the proper installation of the cables on the unit´s terminals so that
parts of accessible wires do not remain live.
CAUTION

9.2.1. INGECON SUN 3Play TL (10~24 kW)
Versions P and P+
For inverters with P and P+ finishes there are two types of DC input connections: with quick connectors or
terminals via packing glands (supplied by Ingeteam).
If using quick connectors, each string has two protection fuses (one at each pole) and current monitoring.
If the connection is made via a terminal and packing glands, the protection fuses and current monitoring are not
operative.
The maximum admissible currents are the following, relative to the type of connection and inverter model:
