Installing the Inverter<br />
Authorised electrician<br />
NOTICE<br />
When the lead impedance is high (i.e. long grid-side leads), the voltage at the grid terminals of the<br />
inverter will increase during feed-in to the grid. The inverter monitors this voltage. If it exceeds the<br />
country-specific line overvoltage limit value, the inverter switches off.<br />
› Ensure that the lead cross-sections are sufficiently large or that the lead lengths are sufficiently<br />
short.<br />
Making the grid connection<br />
↻ Drill a hole for the AC leads into the connection board.<br />
1. Remove the outer cladding of the AC leads.<br />
2. Insert the AC leads through the hole into the connection area through the conduit pipe.<br />
3. Strip the insulation from the AC leads.<br />
4. Open the locks of the PCB terminals.<br />
5. Connect the leads in accordance with the labelling of the PCB terminals.<br />
6. Close the locks of the PCB terminals.<br />
7. Check that all connected leads are tightly seated.<br />
» The inverter is now connected to the power grid.<br />
NOTICE<br />
An AC-side disconnection unit must be provided in the final installation. This disconnection unit<br />
must installed in such a manner that access to it is possible at any time without hindrance.<br />
If a residual current circuit breaker is necessary due to the installation specification, then a type A AFI<br />
(AC/DC-sensitive residual current circuit breaker) must be used.<br />
7.3.2 Connecting the PV generator<br />
Connect the PV generator to the 4 DC positive and the 4 DC negative connection terminals in the connection area<br />
of the inverter.<br />
DANGER<br />
Risk of fatal injury due to contact voltages.<br />
› During installation: Electrically disconnect the DC positive and DC negative from the protective<br />
earth (PE).<br />
Removing the connection without previously disconnecting the inverter from the DC generator can<br />
result in a hazard to health and damage to the inverter.<br />
WARNING<br />
No internal GFDI.<br />
This unit is not provided with a GFDI (ground-fault detector-interrupter). The inverter must be used<br />
with an external GFDI device as required by the article 690 of the national electrical code for the<br />
installation location.<br />
