Creating Equipotential Bonding - Kaco blueplanet 3.0TL3 Series Manual

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.
Connecting the PV generator
↻ DC plug connector configured and PV generator checked to ensure there is no
ground fault.
1 Remove protective caps from the required DC connection plugs on the under-
side of the device.
2 Connect the the DC plug connectors to the DC positive and DC negative connect-
ors in pairs.
» The device is connected to the PV generator.

NOTE
Depending on the local installation specifications, it may be necessary to earth the device with a second
ground connection. To this end, the threaded bolt on the underside of the device can be used.
↻ The device has been installed on the mount.
1 Strip the insulation from the equipotential bonding cable.
2 Furnish the stripped cable with an M4 ring cable lug.
3 Lay the equipotential bonding cable onto the grounding point and attach with
the M4 x 10 bolt and lock washer provided [ W_T30/
4 Check that the connected cable is fitted securely.
» The housing is included in the equipotential bonding.
