2.1 Safety Information

This section contains safety information that must be observed at all times when working on or with the product.

To prevent personal injury and property damage and to ensure long-term operation of the product, read this section carefully and observe all safety information at all times.

Danger to life due to high voltages of the PV array

When exposed to sunlight, the PV array generates dangerous DC voltage which is present in the DC conductors and the live components of the inverter. Touching the DC conductors or the live components can lead to lethal electric shocks. If you disconnect the DC connectors from the inverter under load, an electric arc may occur leading to electric shock and burns.

• Do not touch uninsulated cable ends.

• Do not touch the DC conductors.

• Do not touch any live components of the inverter.

• Have the inverter mounted, installed and commissioned only by qualified persons with the appropriate skills.

• If an error occurs, have it rectified by qualified persons only.

• Prior to performing any work on the inverter, disconnect it from all voltage sources as described in this document (see Section2.2 "Disconnecting the Inverter from Voltage Sources", page7).

Danger to life due to electric shock

Touching an ungrounded PV module or array frame can cause a fatal electric shock.

• Connect and ground the PV modules, array frame and electrically conductive surfaces so that there is continuous conduction. Observe the applicable local regulations.

Risk of burns due to hot enclosure parts

Some parts of the enclosure can get hot during operation.

• During operation, do not touch any parts other than the enclosure lid of the inverter.

Risk of burns from hot heat sink

During operation, the heat sink at the top of the inverter can reach temperatures of over 70°C.

• Do not touch the heat sink.

• If the heat sink is soiled, clean it with a soft brush or a vacuum cleaner.

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.

2 Safety

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.

Procedure:

1. Disconnect the circuit breaker and secure it against reconnection.

2. If an external DC load-break switch is installed, disconnect it from all voltage sources.

3. If an ESS is installed, carefully remove the ESS.

4. If the fault indicator relay is used, switch off the load supply voltage, if necessary.

5. Wait until the LEDs and the display have gone out.

6. Use a current clamp to ensure that no current is present in the DC cables.

7. Release and remove all DC connectors. 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.

8. Ensure that no voltage is present at the DC inputs on the inverter.

9. Pull the AC connection socket out of the AC pin connector on the inverter. Turn the bush insert of the AC connection socket to the left until the AC connection socket releases.

10.

Danger to life due to high voltages

The capacitors in the inverter take tenminutes to discharge.

• Wait tenminutes before opening the inverter.

11.

Damage to the inverter due to electrostatic discharge

Touching electronic components can cause damage to or destroy the inverter through electrostatic discharge.

• Ground yourself before touching any component.
