Disconnecting the Inverter from Voltage Sources

Prior to performing any work on the inverter, always disconnect it from all voltage sources as
described in this section. Always adhere to the prescribed sequence.
Damage to seals on the enclosure lids in subfreezing conditions
If you open the enclosure lids when temperatures are below freezing, the enclosure seals can be
damaged. This can lead to moisture entering the inverter.
• Only open the enclosure lids if the ambient temperature is not below -5°C (23°F)
• If a layer of ice has formed on the seal of the lid when temperatures are below freezing,
remove it prior to opening the enclosure lids (e.g. by melting the ice with warm air).
Observe the applicable safety regulations.
Destruction of the measuring device due to overvoltage
• Only use measuring devices with a DC input voltage range of 1000 V or higher.
Procedure:
1.
Danger to life due to electric shock
• Disconnect the inverter from the utility grid and ensure that it cannot be reconnected.
• Disconnect the inverter from the PV array and ensure that it cannot be reconnected.
2. Wait five minutes until the LEDs on the inverter switch off.
3. Release all screws of the lower enclosure lid using an Allen key (AF 3).
4. Lift and remove the lower enclosure lid from below.
