8 Disconnecting the Inverter from Voltage Sources
Before performing any work on the inverter, disconnect it from all voltage sources as described in this
section. Always adhere strictly to the given sequence.
1. Disconnect the miniature circuit-breaker and secure against reconnection.
2. If an ESS is in use, carefully pull it out.
3. If an external DC switch-disconnector is in use, disconnect it.
4. Use a current clamp to ensure that no current is present in the DC cables.
5. Release and disconnect all DC connectors. To do
so, insert a flat-blade screwdriver or an angled
screwdriver (blade width: 3.5 mm) into one of the
side slots and pull the DC connectors straight out.
Do not pull on the cable.
6. Check that no voltage is present at the DC inputs on
the inverter.
7. Pull the AC coupling socket out of the AC female
connector on the inverter.
8. Wait until the all LEDs and the display have gone out.
