HYD 5/6/8/10/15/20KTL-3PH USER MANUAL
5.5 Electrical connection
The electrical connection is established as follows:
1. Connect PE cable
2. Connect DC input cable
3. Connect battery cable
4. Connect AC output power cable
5. Connect communication cable (optional)
5.6 Connecting the PE cables
Connect the inverter to the equipotential bonding bar by using
the protective earth cable (PE) for grounding.
Pole earthing not permissible!
As the inverter is transformerless, the plus and minus
poles of the PV generator must NOT be earthed.
Otherwise, the inverter will malfunction. In the PV
system, not all live metal parts (e.g. PV module frames,
PV frame, generator connection box housing, inverter
housing) require earthing.
The protective grounding of the chassis shell cannot
replace the PGND cable of the AC LOAD Port. Ensure
that the two PGND cables are reliably connected.
When multiple inverters are deployed, ensure that the
protection ground points of all inverters are
equipotential connected.
1. Remove the insulation of the cable. For outside use,
cables of ≥ 4mm² are recommended for earthing
（ ≥6mm², applicable to French installation standard
requirements）.
