6.1 Removing the Antenna
Required tools:
☐ Long-nosed pliers
Procedure:
1.
Danger to life due to high voltages of the PV array
When exposed to sunlight, the PV array generates dangerous direct voltage. Touching the DC conductors can
lead to lethal electric shocks. Even if the DC load-break switch of the inverter is in the O, position, there will be
dangerous direct voltage present in the DC conductors and on the DC-in connecting terminal plate in the
Connection Unit of the inverter.
• Prior to performing any work on the inverter, always disconnect the inverter from voltage sources on the AC
and DC sides and secure it against reconnection (see the inverter manual).
• Leave the DC-in connecting terminal plate plugged into the Connection Unit of the inverter and only touch it
on the black enclosure.
• Do not remove the DC cable from the connecting terminal plate.
2. Pull the antenna cable plug out of pin connector ANT. 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. Remove the cable gland and antenna cable from the inverter.
6. 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.
6.2 Disposing of the Product
• Dispose of the product in accordance with the locally applicable disposal regulations for electronic waste.
