4.4.2 Connecting the PV generator
Connecting the PV generator
↻ PV generator is dimensioned according to the performance characteristics of
the unit.
1 Remove protective caps from the required DC connection plugs on the under-
side of the device.
2 Connect the DC plug connectors to the DC positive and DC negative connectors
in pairs.
» The device is connected to the PV generator.

4.5 Inserting the overvoltage protection
Information on the overvoltage protection: See http://www.kaco-newenergy.com/de/downloads in the “string in-
verter/manual” category.
4.6 Creating equipotential bonding
↻ The device has been installed on the mount.
1 Undo the cable fitting for housing ground connection [ W_20]
2 Insert the cable for equipotential bonding through the cable fitting provided
into the connection area.
3 Strip the insulation from the equipotential bonding cable.
4 Furnish the stripped cable with an M4 ring cable lug.
5 Lay the equipotential bonding cable onto the grounding point and attach with
the M4 x 10 bolt and lock washer provided [ W_T30/ 2.2 Nm].
6 Check that the connected cable is fitted securely.
7 Tighten the cable fitting for the housing ground connection [ W_20 / 1.5
Nm].

4.7 Connecting the interfaces
4.7.1 Overview
DANGER
Risk of fatal injury due to electric shock!
Severe injury or death may result from improper use of the interface connections and failure to observe pro-
tection class III.
› The SELV circuits (SELV: safety extra low voltage) can only be connected to other SELV circuits with
protection class III.
All interfaces are located on the communication circuit board (HMI board) inside the housing.
