Procedure:
1.
Danger to life due to electric shock
• Ensure that the inverter is disconnected from all voltage sources (see Section 10
"Disconnecting the Inverter from Voltage Sources", page 46).
2. Remove all screws from the enclosure lid and pull the enclosure lid forward smoothly.
3. Remove the grounding conductor from the bottom of the enclosure lid.
4. Prepare the cable:
• Dismantle the cable by no more than 15 mm.
• Strip off the conductor insulation by max. 8 mm.
5. Prepare the cable gland PG16 for connection to the fault indicator relay as follows:
• Remove the swivel nut from the cable gland and remove the filler plug.
• Remove the one-hole cable support sleeve from the cable gland and insert the cable into
the one-hole cable support sleeve.
• Press the one-hole cable support sleeve with the cable into the cable gland and lead the
cable into the inverter.
• Slide the swivel nut over the cable.
6. Connect the cable to the fault indicator relay in accordance with the circuit diagram.
7. Tighten the swivel nut of the cable gland.
8. Establish the grounding conductor connection
between the inverter and enclosure lid.
9. Position the enclosure lid on the enclosure and tighten it using the four screws (torque: 2 Nm).
6.5 DC Connection
6.5.1 Requirements for the DC Connection
Requirements for the PV modules:
☐ All PV modules must be of the same type.
☐ All PV modules must be aligned and tilted identically.
☐ On the coldest day based on statistical records, the open-circuit voltage of the PV array must
never exceed the maximum input voltage of the inverter.
☐ The same number of series-connected PV modules must be connected to each string.
☐ The maximum input current per string must be maintained and must not exceed the through-
fault current of the DC connectors (see Section 11 "Technical Data", page 48).
