11. Configure the energy meter for operation with the
inverter. When doing so, set the DIP switches 7 and
8 to ON (1) and the DIP switches 1 through 6 to 0.
This ensures that the energy meter data can be
transmitted to the inverter.
6.6 Connecting the Switch and Outlet for Secure Power
Supply Operation
Neutral and grounding conductor of output for secure power supply
permanently connected
The inverter's output for secure power supply includes a permanent connection between
neutral and grounding conductor, which cannot be disconnected.
Requirements:
☐ The technical requirements must be met for connecting the switch and outlet for secure power
supply operation (see Section10 "Technical Data", page69).
☐ All electrical installations must be carried out in accordance with the local standards and the
National Electrical Code
®
ANSI/NFPA 70 or the Canadian Electrical Code
®
CSA C22.1.
Residual-current device:
☐ SMA Solar Technology AG recommends to install a residual-current device (type A) between
the inverter's output for secure power supply and the outlet for secure power supply operation,
which trips at a residual current of 30mA. Observe all locally applicable standards and
directives when doing so.
Additionally required material (not included in the scope of delivery):
☐ One standard outlet
☐ One standard switch (e.g. light switch)
☐ Conduits (trade size: 21mm (0.75in) or smaller with suitable reducer bush)
☐ UL-listed raintight or liquidtight conduit fittings (trade size: 21mm (0.75in) or smaller with
suitable reducer bush)
Procedure:
• Connect the outlet for secure power supply operation.
• Connect the switch for secure power supply operation.
