Creating Equipotential Bonding; Sealing The Connection Area - Kaco blueplanet 15.0 TL3 Mode D'emploi

CAUTION
Damage to the PV generator in case of faulty configuration of the DC connector.
A faulty configuration of the DC connector (polarity +/-) causes equipment damage in the DC connection if
it is connected permanently.
› Please check polarity (+/-) of the DC connector before connecting the DC generator.
› Before using the solar modules, check the vendor's calculated voltage values against those actually
measured. The DC voltage of the PV system must not exceed the maximum no-load voltage at any
time.
