DANGER

Danger to life due to electric shock when touching live system components in case of a ground fault
If a ground fault occurs, parts of the system may still be live. Touching live parts and cables results in death or lethal injuries due to electric shock.

Disconnect the product from voltage sources and ensure it cannot be reconnected before working on the device.
Only touch the cables of the PV modules on their insulation.
Do not touch any parts of the substructure or frame of the PV array.
Do not connect PV strings with ground faults to the inverter.
Ensure that no voltage is present and wait 5 minutes before touching any parts of the PV system or the product.

Danger to life due to electric shock when live components or DC cables are touched
When exposed to light, the PV modules generate high DC voltage which is present in the DC cables. Touching live DC cables results in death or lethal injuries due to electric shock.

Do not touch non-insulated parts or cables.
Install external DC load-break switch (e.g., a PV junction box including a load-break switch) between the inverter and PV array.
Disconnect the PV array from the inverter via an external DC load-break switch (e.g. via a PV junction including a load-break switch). Switch off and secure the DC load-break switch against reconnection.
Disconnect the product from voltage sources and ensure it cannot be reconnected before working on the device.
Wear suitable personal protective equipment for all work on the product.

Danger to life due to electric shock in case of overvoltages and if surge protection is missing
Overvoltages (e. g. in the event of a flash of lightning) can be further conducted into the building and to other connected devices in the same network via the network cables or other data cables if there is no surge protection. Touching live parts and cables results in death or lethal injuries due to electric shock.

Ensure that all devices in the same network are integrated in the existing overvoltage protection.
When laying the network cable outdoors, ensure that there is suitable surge protection at the network cable transition from the product outdoors to the network inside the building.
The Ethernet interface of the product is classified as “TNV-1” and offers protection against overvoltages of up to 1.5 kV.

WARNING

Danger to life due to fire when failing to observe torque specifications on live bolted connections
Failure to follow the specified torques reduces the ampacity of live bolted connections and the contact resistances increase. This can cause components to overheat and catch fire. Death or lethal injuries can result.

Ensure that live bolted connections are always tightened with the exact torque specified in this document.
Only use suitable tools when working on the device.
Avoid repeated tightening of live bolted connections as this may result in inadmissibly high torques.

WARNING

Danger to life due to fire and explosion
In rare cases, an explosive gas mixture can be generated inside the product under fault conditions. In this state, switching operations can cause a fire inside the product or explosion. Death or lethal injuries due to hot or flying debris can result.

In the event of a fault, do not perform any direct actions on the product.
Ensure that unauthorized persons have no access to the product.
Disconnect the PV array from the inverter via an external disconnection device. If there is no disconnecting device present, wait until no more DC power is applied to the inverter.
Disconnect the AC circuit breaker, or keep it disconnected in case it has already tripped, and secure it against reconnection.
Only perform work on the product (e.g., troubleshooting, repair work) when wearing personal protective equipment for handling of hazardous substances (e.g., safety gloves, eye and face protection, respiratory protection).

WARNING

Danger to life due to electric shock from destruction of the measuring device due to overvoltage
Overvoltage can damage a measuring device and result in voltage being present in the enclosure of the measuring device. Touching the live enclosure of the measuring device results in death or lethal injuries due to electric shock.

Only use measuring devices with a measurement ranges designed for the maximum AC and DC voltage of the inverter.

WARNING

Risk of injury due to toxic substances, gases and dusts.
In rare cases, damages to electronic components can result in the formation of toxic substances, gases or dusts inside the product. Touching toxic substances and inhaling toxic gases and dusts can cause skin irritation, burns or poisoning, trouble breathing and nausea.

Only perform work on the product (e.g., troubleshooting, repair work) when wearing personal protective equipment for handling of hazardous substances (e.g., safety gloves, eye and face protection, respiratory protection).
Ensure that unauthorized persons have no access to the product.

CAUTION

Risk of burns due to hot enclosure parts
Some parts of the enclosure can get hot during operation. Touching hot enclosure parts can result in burn injuries.

During operation, do not touch any parts other than the enclosure lid of the inverter.
Wait until the inverter has cooled down before touching the enclosure.

Risk of injury due to weight of product
Injuries may result if the product is lifted incorrectly or dropped while being transported or mounted.

Transport and lift the product carefully. Take the weight of the product into account.
Wear suitable personal protective equipment for all work on the product.
Transport the product using the carrying handles or hoist. Take the weight of the product into account.
Use all carrying handles provided during transport with carrying handles.
Do not use the carrying handles as attachment points for hoist equipment (e.g. straps, ropes, chains). Insert eye bolts into threads provided on top of the product to attach the hoist system.

NOTICE

Damage to the enclosure seal in subfreezing conditions
If you open the product when temperatures are below freezing, the enclosure seals can be damaged. Moisture can penetrate the product and damage it.

Only open the product if the ambient temperature is not below -5°C (23°F).
If a layer of ice has formed on the enclosure seal when temperatures are below freezing, remove it prior to opening the product (e.g. by melting the ice with warm air).

Damage to the product due to cleaning agents
The use of cleaning agents may cause damage to the product and its components.

Clean the product and all its components only with a cloth moistened with clear water.

Damage to the inverter due to switching operations on the transformer
If voltages are present in the inverter, switching operations on the transformer can lead to large fluctuations in the voltage in the inverter. Large fluctuations in voltage can damage components in the inverter.

Disconnect the inverter from voltage sources before performing any switching operations on the transformer.

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.

Damage to the product due to sand, dust and moisture ingress
Sand, dust and moisture penetration can damage the product and impair its functionality.

Only open the product if the humidity is within the thresholds and the environment is free of sand and dust.
Close tightly all enclosure openings.

The country data set must be set correctly.
If you select a country data set which is not valid for your country and purpose, it can cause a disturbance in the PV system and lead to problems with the grid operator. When selecting the country data set, you must always observe the locally applicable standards and directives as well as the properties of the PV system (e.g. PV system size, grid-connection point).

If you are not sure which standards and directives are valid for your country or purpose, contact the grid operator.
