10 Disconnecting the Sunny Multigate from Voltage
Sources
Risk of electric shock due to contact with live components when opening the
Sunny Multigate
There are live components inside the Sunny Multigate. There is a risk of electric shock if you open
the Sunny Multigate.
• Never open the Sunny Multigate.
Before working on the Sunny Multigate, always disconnect it from all voltage sources as described
in this section.
Procedure:
1.
Danger to life due to electric shock
• Disconnect the circuit breaker and secure it against reconnection.
2. Ensure that no voltage is present between the conductors L and N at the AC terminal Grid
using a suitable measuring device.
3. Ensure that no voltage is present between the conductor L and the grounding conductor at the
AC terminal Grid using a suitable measuring device.
4. Ensure that no voltage is present between the conductors L and N at the AC terminal Inverter
using a suitable measuring device.
5. Ensure that no voltage is present between the conductor L and the grounding conductor at the
AC terminal Inverter using a suitable measuring device.
