6.1 Removing the Antenna
Required tools:
☐ Long-nosed pliers
Procedure:
1.
DANGER
Danger to life due to high voltages of the PV array
When exposed to sunlight, the PV array generates dangerous DC voltage, which is present
in the DC conductors and the live components of the inverter. Touching the DC conductors
or the live components can lead to lethal electric shocks.
• Prior to performing any work on the inverter, always disconnect the inverter from
voltage sources on the AC and DC sides as described in the inverter manual. When
doing so, note that even if the DC load-break is switched off, there will be dangerous
direct voltage present in the DC conductors of the inverter.
2. Pull the antenna cable plug out of pin connector
ANT. using long-nosed pliers. of the
communication assembly using long-nosed pliers.
Ensure that the antenna cable is pulled out at 90°
to the communication assembly so that the plug
does not get caught.
3. Unscrew the swivel nut from the cable gland.
4. Unscrew and remove the counter nut of the cable gland.
5. If necessary, remove the cable gland and antenna cable from the inverter.
6. If necessary, seal the enclosure opening of the inverter with the corresponding sealing plug.
7. Close the inverter and recommission it (see inverter manual).
8. At the antenna bracket, unscrew the antenna from the antenna cable plug.
9. Unscrew the counter nut from the plug of the antenna cable.
10. Remove the antenna cable from the antenna bracket.
11. Remove the screws of the antenna bracket.
12. Unscrew and remove the antenna bracket.
