2 Safety
After installation of the Rooftop Communication Kit, the secure power
supply operation is no longer supported.
The Rooftop Communication Kit supports the Rapid Shutdown function. A rapid shutdown is
triggered in the event of a grid failure or an interruption of the AC supply of the inverter. Thus
the supply of the outlet for secure power supply operation is no longer possible.
• If a switch and an outlet for secure power supply operation are connected to the inverter,
the connections for the secure power supply operation have to be removed from the
inverter before installation of the Rooftop Communication Kit:
– Disconnect the inverter from all voltage sources (see inverter manual).
– Remove the conductors of the outlet for secure power supply operation from the
terminal block SPS. To release the conductors from the terminals, open the terminals
with a flat-blade screwdriver (blade width: 3.5°mm (0.14°in)).
– Screw out the screws from the SPS terminal block using a flat-blade screwdriver
(blade width: 3.5 mm (0.14 in)) and pull the terminal block out of the slot.
– Remove the equipment grounding conductor of the outlet for secure power supply
operation from the equipment grounding terminal. To do this, remove the screw (TX
25) and remove the equipment grounding conductor from the inverter; screw each
screw back in (TX 25).
– For secure power supply operation, remove the plug with the switch conductors from
the SPS slot of the communication assembly.
– Pull all conductors for secure power supply operation out of the inverter and uninstall
the switch and outlet of secure power supply operation.
Electrical installations (only applies to North America)
All electrical installations must be carried out in accordance with the local standards and the
National Electrical Code
• Before connecting the inverter to the utility grid, contact your local grid operator. The
electrical connection of the inverter must be carried out by qualified persons only.
• Ensure that no cables used for electrical connection are damaged.
