2. Tighten all six screws with an Allen key (AF 3) in
the order 1 to 6 (torque: 2.0 Nm ± 0.3 Nm). By
tightening the screws in the prescribed order,
you avoid warping the enclosure lid, which
would keep it from sealing correctly.
Useful hint: If the screws fall out of the lower
enclosure lid, insert the long screw into the lower
middle hole and the five short screws into the
other holes.
3. Securely plug in the ESS. The ESS must be aligned parallel to and flush with the enclosure.
4. Switch on the circuit breaker of all three line conductors.
5. If the multifunction relay is used, connect the supply voltage to the load.
☑ All three LEDs start to glow and the start-up phase begins. The start-up phase may take several
minutes.
☑ The green LED is glowing and the display alternates automatically between the device type,
firmware version, the serial number or designation of the inverter, the NetID, the configured
country data set and the display language.
✖ The green LED is flashing?
Possible cause of error: the DC input voltage is still too low or the inverter is monitoring the
utility grid.
• Once the DC input voltage is sufficiently high and the grid connection conditions are met,
the inverter will start operation.
✖ The red LED is glowing and an error message and event number appear in the display?
• Rectify the error (see the service manual at ).
