6.3.3 Connecting Additional Earthing
You can carry out additional earthing of the inverter enclosure if local requirements stipulate
additional earthing or equipotential bonding. This will prevent touch current if the original protective
conductor fails.
Additional required material (not included in scope of delivery):
☐ Ring terminal lug M6
☐ 1 earthing cable
Cable requirement:
☐ Earthing cable cross-section: max. 16 mm²
Procedure:
1. Strip the earthing cable insulation.
2. Thread ring terminal lug onto earthing cable.
3. Align washer, earthing cable with ring terminal lug
and conical spring washer on the cheese-head
screw M6x12. The teeth of the conical spring
washer must be facing the metal shackle on the
inverter.
4. Insert the cheese-head screw through the metal
shackle on the inverter and screw onto the wall
mounting bracket (torque: 6 Nm).
6.4 DC Connection
6.4.1 Requirements for DC Connection
Requirements for the PV modules:
☐ All PV modules must be of the same type.
☐ The same number of series-connected PV modules must be connected to all strings.
☐ All PV modules must have the same alignment.
☐ All PV modules must have the same tilt angle.
☐ The maximum input current per string must be complied with and must not exceed the
through-fault current of the DC connectors (see Section 12 "Technical Data", page 60).
☐ The thresholds for the input voltage and the input current of the inverter must be observed
(see Section 12 "Technical Data", page 60).
☐ On the statistically proven coldest day of the year, the open-circuit voltage of the PV array
should never exceed the maximum input voltage of the inverter.
☐ The positive connection cables of the PV modules must be fitted with the positive DC connectors
(for information on assembling DC connectors, see the DC connector installation manual).
