Damage to the seal of the enclosure lid in sub-zero conditions
If you open the enclosure lid in sub-zero conditions, the sealing of the enclosure lid can be
damaged. This can lead to moisture entering the inverter.
• Do not open the inverter at ambient temperatures lower than -5°C.
• If a layer of ice has formed on the seal of the enclosure lid in sub-zero conditions, remove it
prior to opening the inverter (e.g. by melting the ice with warm air). Observe the applicable
safety regulations.
Dust and water intrusion can damage the inverter.
If the inverter is equipped with an ESS, the inverter complies with degree of protection IP65 when
the ESS is plugged in and the inverter is closed.
If the ESS is not plugged in, moisture and dust can penetrate and damage the inverter. In order to
sufficiently protect the inverter during decommissioning, the DC inputs must be closed.
• Unlock and remove all DC connectors.
• Open all DC connectors.
• Close all DC inputs with the corresponding DC connectors and the supplied sealing plugs.
• Securely plug the ESS back in.
Damage to the display or the type label due to the use of cleaning agents
• If the inverter is dirty, clean the enclosure, the enclosure lid, the type label, the display and
the LEDs with a damp cloth only.
Damage to the inverter due to the use of cleaning agents
• If the inverter is dirty, clean the enclosure, the enclosure lid, the type label and the LEDs using
only clean water and a cloth.
2.2 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.
Destruction of the measuring device due to overvoltage
• Only use measuring devices with a DC input voltage range of 600 V or higher.
