De-energising the inverter
When working in the terminal compartment
When working in the inverter's terminal compartment, this area must be de-energised.
DANGER
Risk of death due to electrical shock and discharge!
De-energise device and secure against being switched on again. De-energising the inverter
It is imperative that these steps are carried out:
- Turn the DC switch on the inverter to OFF. DC switch on the inverter
- If used, switch off power supply for switched outputs Switched outputs
- Switch off the AC line circuit breaker.
- Secure the entire voltage supply against being restarted.
- The inverter’s terminal compartment is now voltage-free (high voltage). The Smart Communication Board (SCB) is still supplied with voltage by the PV string and can display values in the inverter’s display. The levels of voltage on the SCB are very low and not dangerous at all. Work can now be carried out in the inverter's terminal compartment or on the AC line.
DANGER
Risk of death due to electrical shock and discharge!
Further steps should be taken when working on the DC feed cables (PV or battery). These steps can be found on the following page.
