Country data set for operation with external decoupling protection
When operating the PV system with external decoupling protection, the inverter has the
additional country data set Medium-Voltage Directive (Germany) or MVtgDirective. This
country data set allows you to extend the operating range of the inverter for voltage and
frequency. This country data set should only be selected if the PV system is disconnected via
external decoupling.
• If the country data set for operation is set with external decoupling protection, only
operate the inverter with an external three-phase decoupling protection. Without external
three‑phase decoupling protection, the inverter will not disconnect from the utility grid
when the country-specific standard requirement is exceeded.
Procedure:
1. Determine the rotary switch position for your country and purpose. Call up the Technical
Information "Overview of the Rotary Switch Settings" at www.SMA-Solar.com.
2.
Danger to life due to high voltages
• Ensure that the inverter is disconnected from all voltage sources and that the enclosure lid
is removed (see Section 9, page 40).
3. Set the rotary switches A and B to the required
position using a flat-blade screwdriver (blade
width: 2.5 mm).
☑ The inverter will adopt the setting after commissioning. This can take up to five minutes.
7.3 Commissioning the Inverter
Requirements:
☐ The inverter must be correctly mounted.
☐ The circuit breaker must be correctly rated and mounted.
☐ All cables must be correctly connected.
☐ Unused DC inputs must be sealed using the corresponding DC connectors and sealing plugs.
☐ The country data set must be set correctly for the country or the purpose.
☐ Unused enclosure openings must be sealed tightly. The factory-mounted filler plugs can be
used for that purpose.
