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 Section10, page43).
3. Set the rotary switches A and B to the required
position using a flat-blade screwdriver (blade
width: 2.5mm).
☑ 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.
Procedure:
1. Make sure that the AC cable is routed so that it cannot be damaged by the partition in the
lower enclosure lid.
2. Insert the lower enclosure lid from above and
flip it down. The screws must protrude from the
lower enclosure lid.
